The document discusses animal disease ecology and transmission. It defines key terms like infection, disease, ecology, and transmission. It then discusses how environmental conditions, animal hosts, vectors, and pathogens interact to lead to disease transmission. Specifically, it explores how factors like climate change, land use changes, intensive farming practices, and globalization can influence disease emergence and spread among animal populations.
Animal Disease Ecology and Amp; TransmissionPerez Eric
1. Animal disease ecology and transmission involves the study of how diseases spread between animals and their environments. Key concepts include reservoirs, where pathogens live and multiply; ports of exit, how pathogens leave an infected host; and modes of transmission, how pathogens are passed between hosts.
2. Many factors can influence disease emergence and spread, including climate change, land use changes, increased animal densities, and globalization. Climate change can alter disease patterns by changing temperatures and rainfall in ways that increase vector populations. Changes in land use and encroachment on animal habitats can increase contact between wildlife and livestock.
3. Integrated policies are needed to address socioeconomic, institutional, and production factors that influence disease risks at the

Disease ecology is the study of interactions between pathogens, hosts, and their environment. It is an interdisciplinary field that combines epidemiology, ecology, and other disciplines to better understand how environmental changes can impact disease transmission and emergence. The challenges include predicting how human alteration of landscapes might lead to new diseases spreading from wildlife to humans, and developing surveillance methods to detect diseases early. Understanding disease ecology is important for preventing changes in pathogen virulence and managing diseases at the population level.

Global veterinary and medical perspectives on one healthJess Vergis
This document discusses the concepts of One Health and the interconnectedness of human, animal, and environmental health. It outlines how increased human population, urbanization, agricultural intensification, and encroachment into wildlife habitats have contributed to the emergence of zoonotic diseases. Over 60% of infectious diseases are zoonotic, with 71.8% originating from wildlife. The document then examines the historical foundations of comparative medicine and the development of veterinary science and its role in public health. It discusses how the One Health approach aims to address modern problems through cross-sectoral collaboration between medical, veterinary, and environmental professionals.
Social dimensions of zoonoses in interdisciplinary researchNaomi Marks
This document summarizes Dr. Hayley MacGregor's research on the social dimensions of zoonoses (diseases that can be transmitted between animals and humans) in emerging livestock systems. It discusses two key areas: 1) how cultural and social practices influence zoonotic risk, and 2) the relationship between humans and animals. For area 1, it describes how factors like intensification of production, supply chains, processing practices, markets and consumer demand can drive zoonotic risk. For area 2, it discusses how human-animal relations blur traditional categories, and how the health of humans and animals is interdependent.
1) The document discusses several zoonotic diseases including West Nile virus, rabies, and brucellosis. It describes the pathogens, transmission cycles between animals and humans, clinical manifestations in humans, and national surveillance efforts.
2) For diseases like rabies and brucellosis, the national surveillance involves mandatory reporting of human cases, monitoring of infected animals, and collaboration between human and veterinary agencies.
3) One health approaches discussed include integrating epidemiological data between human and veterinary fields to more rapidly detect and respond to zoonotic outbreaks.
The One Health Center aims to improve global health through an integrated approach addressing connections between human, animal, food, and environmental factors. Its mission is to assess and respond to health problems at this human-animal-environment interface through multidisciplinary and collaborative efforts. Key areas of research and intervention include improved water management, poultry immunization, disease surveillance, food safety, and combating malnutrition. A signature project will pilot interventions in these areas in Uganda to evaluate the added benefits of One Health approaches.

One World - One Health presentation Katinka de Balogh FAOHarm Kiezebrink
During the FVE conference in Brussels on April 7, 2014, Katinka de Balogh, leader the global Veterinary Public Health activities of the FAO, presented the One-Health approach to highlight the importance of prevention, ensuring health and welfare of people and animals in a globalized environment:
• The benefit coming from the implementation of good health management in practice, both in terms of health and welfare, as well as, of financial sustainability
• The importance of coordinating actions in both sectors via a One-Health approach, with a particular focus on zoonotic diseases
• The role of the medical and veterinary profession in assuring these matters and educating the society
Katinka de Balogh is of Dutch and Hungarian origins and grew up in Latin-America. She studied veterinary medicine in Berlin and Munich and graduated and obtained her doctorate in tropical parasitology from the Tropical Institute of the University of Munich in 1984. In the late 80’s she had spent two years as a young professional at the Veterinary Public Health Unit of the World Health Organization (WHO) in Geneva. In 2002 she started working at the Food and Agriculture Organization of the United Nations (FAO) in Rome.

International Threats of Zoonotic Diseases - International Conference on One ...Tata Naipospos
The document summarizes an international conference presentation on zoonotic diseases and their threats. It notes that emerging zoonotic diseases pose an increasing global threat due to factors like population growth, increased animal production and trade, and human encroachment on wildlife habitats. An interdisciplinary "One Health" approach integrating human, animal, and environmental health is needed to monitor and control zoonotic diseases, which account for over 60% of all known human pathogens. Collaboration across medical, veterinary and policy sectors can help achieve efficiencies and early detection of outbreaks.
Agricultural intensification and Nipah virus emergenceNaomi Marks
Presentation by Dr Jonathan Epstein, EcoHealth Alliance, at the One Health for the Real World: zoonoses, ecosystems and wellbeing symposium, London 17-18 March 2016
Antibiotic resistance is a complex public health issue that requires a One Health approach. The overuse and misuse of antibiotics in human medicine, agriculture, and the environment has contributed to the emergence and spread of antibiotic-resistant bacteria. A holistic, multisectoral response is needed that promotes prudent antibiotic use and prevents infection across human, animal, agricultural, and environmental domains.
This document discusses influenza pandemic preparedness. It notes that influenza A viruses can undergo major antigenic shifts, causing worldwide pandemics with high morbidity and mortality, such as in 1918, 1957, and 1968. Epidemics are primarily caused by influenza A and B viruses, while pandemics are caused by new influenza A viruses emerging from animal reservoirs. The goals of pandemic preparedness are to reduce morbidity and mortality from influenza, decrease social and economic impacts, and develop coordinated international, national, and local plans that strengthen surveillance, stockpile vaccines and antivirals, optimize health systems and resources, and educate the public and healthcare providers.
The One Health approach recognizes that human health, animal health, and environmental health are interconnected. It aims to attain optimal health for people, animals, and the environment through collaboration across multiple disciplines. Key agencies like FAO, OIE, and WHO have developed strategic frameworks to foster cooperation between sectors. Case studies demonstrate how delayed or lack of coordination between human and animal health sectors increased costs and impacted control of diseases like Nipah virus. Antimicrobial resistance is another issue that requires a One Health approach.
The document discusses World Health Day 2014 and the theme of vector-borne diseases. It notes that World Health Day is celebrated annually on April 7th to mark the founding of the WHO. The 2014 theme focused on diseases spread by vectors like mosquitoes, ticks, and flies. The document provides information on vectors, definitions, types of vector-borne disease transmission, how climate change can increase the spread and range of such diseases, and emphasizes the need for prevention through measures like bed nets and insect repellent to protect against vector-borne illnesses.
Infectious diseases pose a major risk to public health in Canada. There are several contributing factors, including rising antimicrobial resistance due to overprescription of antibiotics, increased risk of vector-borne and waterborne diseases due to climate change, and higher rates of sexually transmitted and healthcare-associated infections. Better surveillance systems, public health initiatives, and prevention programs are needed to address this growing threat.
Behaviouralism emerged after World War 2 as a challenge to existing international relations theories. It takes a positivist and scientific approach, emphasizing observable data over subjective interpretations. Behaviouralism views human behaviour as shaped by external environmental factors rather than innate drives, and aims to discover laws that can predict international relations. It uses scientific methods like hypothesis testing and focuses on quantifiable and measurable variables.
This document outlines three theoretical paradigms in political science: traditionalism, behavioralism, and post-behavioralism. Traditionalism examines the formal rules and institutions of politics through historical and normative analysis. Behavioralism stresses empirical observation and data collection over historical analysis. Post-behavioralism emerged as a reaction against behavioralism, arguing that political science should be both empirically reliable and relevant, and that the topics studied can have real-world ethical implications related to issues like war and human rights.

This document discusses different approaches to conceptualizing industrial relations. It begins by defining industrial relations and outlining its scope. It then summarizes John Dunlop's influential systems approach. Dunlop conceptualized an industrial relations system as having three main elements: actors (managers, workers, government agencies), contexts (technological, market, societal power structures) and an ideology that binds them. The contexts particularly shape the system, such as a industry's technology influencing management-labor relations. This systems approach was influential in establishing industrial relations as a discipline.
The document discusses various perspectives on the meaning and scope of international relations (IR). It addresses traditional narrow and broader views, as well as perspectives put forth by scholars like Holsti, Wright, Hoffmann, and Mathiesen. Key aspects of IR discussed include a wide variety of official and unofficial transnational relations. The document also examines different phases and approaches to studying IR, such as traditional, scientific, behavioral, and post-behavioral approaches. Finally, it outlines several models of international systems put forth by scholars like Kaplan.
Human ecology is an interdisciplinary field that studies the relationship between humans and their natural, social, and built environments. The postulate of human ecology states that on a limited area with limited resources, only a limited number of people with a certain behavior and culture can live to a certain standard while maintaining environmental quality. Overpopulation puts pressure on resources and can lead to issues like conflict over scarce resources, global migration, climate change, threats to political stability, and may even cause industrial civilization to collapse irreversibly. Recognizing the interdependence between humans and the environment, solutions need to be found through cooperation and changing perspectives on sustainability.
This PowerPoint illustrates the situation of the lower classes in Russia after the Emancipation through art and presents early Russian radicalism as background for discussion of Dostoevsky's Notes from the Underground.
The document discusses ecology and human ecology. It defines ecology as the study of relationships between organisms and their environment. It describes ecosystems as hierarchical systems composed of interacting species and abiotic factors. Human ecology examines practical applications of ecology in areas like conservation, resource management, urban planning, and disease transmission. The role of human behavior, ecology of vectors/hosts, and pathogen virulence are important factors in infectious disease transmission. Climate is often cited as influencing disease distribution but its impact depends on other complex ecological relationships.
Human ecology home work_society.18.3.2011Mauri Ahlberg
Professor Mauri Ahlberg gave a keynote lecture on human ecology, sustainable living, and the importance of nature. He discussed how home refers to relationships more than physical structures, and emphasized learning through inquiry and dialogue. Ahlberg believes cultivating gratitude, focusing on nature, and sharing knowledge openly can promote well-being and bring people together.
Epidemiology is the study of the distribution and determinants of health-related states in populations and the application of this study to disease prevention and control. The document traces the history of epidemiology from its early foundations in the work of Hippocrates and John Graunt to its modern applications in identifying risk factors for diseases and conditions. It discusses how epidemiology has evolved from a focus on infectious diseases to also study chronic diseases, injuries, behaviors, and genetic/molecular factors. The epidemiological transition framework describes stages in changing disease patterns as societies develop, from an early focus on famine/pandemics to modern burdens of noncommunicable diseases.
This document discusses the philosophies of materialism and pragmatism and their implications for education. It provides background on historical materialism and key materialist philosophers like Democritus, Feuerbach, and Marx. It also explains the basic concepts of materialism, which asserts that material reality is fundamental and ideas are determined by material conditions. The document then discusses pragmatism, tracing its origins and defining it as evaluating ideas based on their practical consequences. It outlines pragmatism's view of reality, knowledge, and values. Finally, the implications of materialism and pragmatism for education are summarized, including their views on curriculum, teaching methods, and the roles of teachers and students.
Green Revolution and Physical Geography of indiaaheathcock
This document provides information about the physical geography, climate, and cultural hearths of India. It discusses how the Indian subcontinent was formed by the collision of the Indian and Eurasian tectonic plates, which created the Himalayan mountain range. It describes India's summer and winter monsoon patterns and their effects. The document also notes some of India's natural resources, such as fertile soil and tea production. It provides background on subsistence and commercial farming before discussing the Green Revolution, which aimed to increase food production through new seeds, fertilizers, and irrigation techniques. While this solution boosted wheat yields, it also had disadvantages like increased pollution, high costs that only wealthy farmers could afford, and overreliance on specific seed
Trypanosomiasis is a vector-borne parasitic disease caused by Trypanosoma parasites. There are two main forms: African trypanosomiasis (sleeping sickness) transmitted by tsetse flies, and American trypanosomiasis (Chagas disease) transmitted by triatomine bugs. African trypanosomiasis is found in central and west Africa and causes a slow progression of symptoms, while American trypanosomiasis is found in Latin America and causes an initial acute phase followed by a chronic phase in some patients. Both forms require treatment with drugs to eliminate the parasites from the body.

Humanistic geography focuses on subjective human experience and the meanings that people associate with places. It studies how individuals structure their environment and experience space. Key aspects include idealism, phenomenology, and a focus on the individual as the unit of analysis. Humanistic geography emerged in the 1970s as an alternative to quantitative spatial science approaches. It emphasizes everyday life and the cultural meanings embedded in landscapes. Major figures like Tuan, Buttimer, and Relph explored concepts like the lifeworld, insideness/outsideness, and how space is understood through place. Humanistic geography brought more attention to place and symbolic meanings over objective spatial facts.
developments of human centered theoriesPooja Kumari
This document provides information about behaviouralism in geography. It discusses how behaviouralism developed due to dissatisfaction with positivist models based on economic rationality. The behavioural approach emphasizes subjective and decision-making variables that influence human-environment relationships. It lists the objectives and fundamental arguments of behavioural geography, including that people have environmental images that influence decision-making. The document also provides details about humanistic geography and its criticisms of quantitative models.
This document discusses key concepts in population ecology, including:
- Population is defined as all individuals of a species living in an area. Demography is the statistical study of populations.
- Population size, density, distribution, and changes over time are important to study. Populations can experience exponential or logistic growth depending on available resources.
- Survivorship curves (Type I, II, III) describe mortality patterns. Reproductive strategies also influence population growth.
- Human population growth has increased due to improved health and technology, though uncontrolled growth risks environmental damage.

This document discusses various types of ecosystems. It begins by defining ecology as the study of how living organisms interact with each other and their environment. It then explains that an ecosystem includes all organisms and non-living elements in a particular area. It discusses ecological succession, food chains, food webs, and ecological pyramids. It also describes several ecosystem types - forests, grasslands, deserts, and aquatic ecosystems - and provides examples of ecosystems within each type. It concludes by stating that after learning about ecosystems, we can infer that humans are part of nature and have an important responsibility to conserve and maintain ecosystems.
This document outlines the key principles of pragmatism and progressivism in education as espoused by John Dewey. It advocates that education should focus on how to think rather than what to think, and should be a process of living rather than preparation for life. Schools should foster habits of thought and initiative to help students reach their potential. Pragmatism emphasizes learning through experience and problem-solving. Progressivism criticizes traditional practices like rote memorization and advocates student-centered, experiential, and project-based learning.
The document defines One Health as a collaborative approach to attaining optimal health for humans, animals, and the environment. It outlines the components of the One Health approach, including the geographical, ecological, human activities, and food/agricultural components. Complex health problems that require a One Health approach are identified as emerging/re-emerging pandemics, zoonotic diseases, antimicrobial resistance, environmental hazards, food safety, and disasters. Key stakeholders in addressing these problems include patients, physicians, employers, insurance companies, pharmaceutical firms, and the government. Collaboration between these groups is important for promoting public health outcomes.
Ecohealth: Research to Policy Influence - Canada International Development Re...Tata Naipospos
The document discusses the ecosystem approaches to human health research framework. It provides two case examples of emerging infectious diseases - Nipah virus and H5N1 avian influenza - to illustrate how this framework works. For both cases, a transdisciplinary investigation considered social, ecological, economic, and behavioral factors and their interactions. This led to insights into disease emergence and spread. The research then influenced policies to regulate industries, improve sanitation, and stem wildlife trade - protecting both human and animal health.
This document discusses emerging and re-emerging infectious diseases. It begins with trends in infectious diseases, then defines emerging and re-emerging diseases. Factors that contribute to emergence include changes in the agent, host, and environment. Examples are provided of diseases that have emerged or re-emerged recently, including SARS, avian influenza, hepatitis C, and antibiotic resistance. The response from public health is also mentioned.
This document discusses zoonotic and vector borne diseases. It begins with an introduction to zoonotic diseases, which are diseases that can spread between animals and humans. These diseases are caused by viruses, bacteria, parasites or fungi. The document then discusses the main mechanisms of infection such as direct contact, indirect contact, vector-borne transmission, foodborne transmission, and waterborne transmission. It identifies populations that are at high risk of zoonotic diseases such as children, elderly adults, immunocompromised individuals, and pregnant women. The document also examines the environmental and anthropogenic factors that contribute to the emergence and spread of zoonotic diseases. Finally, it provides examples of major zoonotic diseases and discusses Malaysia's mult
Combating cummunicable diseases at the farm - wildlife interfaceH. (Harry) Rozendaal
This document discusses the risks of communicable diseases spreading between domesticated animals and wildlife. It provides examples of diseases that have spread in this way, such as avian influenza between poultry and wild birds, bovine tuberculosis between cattle and wildlife like possums and deer, and African swine fever between domestic pigs and wild boar. The author argues that minimizing contact between domestic and wild animals, quickly controlling outbreaks in domestic populations, and avoiding disturbing, gathering or feeding wild animals can help curb the cycle of infection at the wildlife-domestic animal interface.
Emerging and re emerging infectious diseasesShaharul Sohan
This document discusses emerging and re-emerging infectious diseases. It provides examples of diseases that have emerged in recent decades like Ebola, SARS, and HIV/AIDS. It also gives examples of diseases that were once under control but are re-emerging like tuberculosis, malaria, and cholera. The document explores factors that contribute to disease emergence such as ecological disruption, globalization, and breakdowns in public health infrastructure. It emphasizes that infectious diseases remain a major global health challenge.
This document discusses factors responsible for emerging and re-emerging infectious diseases. It argues that while pathogens, hosts, vectors, and environment have traditionally been seen as the main determinants of infectious disease emergence and transmission, human intervention through progress in science and technology should be considered a fifth key determinant. It provides examples of how various aspects of scientific and technological progress, such as intensive agriculture, antibiotic overuse, bioterrorism, and changes in food processing and transportation, have contributed to disease emergence and spread in recent decades.
This document discusses emerging and re-emerging infectious diseases. It begins by outlining the objectives and key terms. It then provides background on how human diseases have changed as humans migrated and civilization developed. The document identifies several potential contributing factors to new diseases emerging, such as population growth, poverty, human behavior changes, and technological advances. It also discusses challenges like antibiotic resistance and how diseases spread through increased population movement and globalization. Finally, it examines the development of global surveillance networks and international agreements to control infectious diseases.

What is an Emerging Infectious Disease
The term "emerging infectious diseases" refers to diseases of infectious origin whose incidence in humans has either increased within the past two decades or threatens to increase in the near future.
REASONS FOR THE EMERGENCE OF INFECTIOUS DISEASE
There are a number of specific explanations responsible for disease emergence that can be identified in most all cases (Table 7-1a-d).
Table 7-1a
Viral
Viral diseases that have been identified since 1973
1977 Ebola, Marburg
Origin undetermined. (Importation of monkeys associated with outbreaks in these primates in Europe and the United States)
1980 HTLV Influenza (pandemic)
Pig-duck agriculture thought to contribute to reassortment of avian and mammalian influenza viruses
1983 HIV
Transmission by intimate contact as in sexual transmission, contaminated hypodermic needles, transfusions, organ transplants. Contributing condition that spread the disease include war or civil conflict, urban decay, migration to cities and travel

Current and future challenges of the poultry industrymithu mehr
The document discusses current and future challenges facing the poultry industry. It identifies strong global competition, changes in social perceptions around food safety and animal welfare, and emerging diseases as major challenges. Controlling foodborne pathogens like Salmonella and Campylobacter in poultry products will be an ongoing public health issue. Developing antibiotic resistance in bacteria is another concern, as is ensuring high animal welfare standards as consumer expectations increase. Overall, the poultry industry will need to address these complex challenges through cooperation across the production chain.

This document discusses the importance of biodiversity for human health and society. It begins by outlining the objectives of the lesson, which are for students to understand the interrelatedness of society, environment and health, and to analyze how everyday tasks impact biodiversity and wellness. It then discusses how biodiversity loss is a global problem, with species declining worldwide due to human causes like habitat destruction. Loss of biodiversity harms ecosystems and can lead to health issues for humans. Later sections explore the nutritional and health impacts of biodiversity loss, how reduced diversity increases transmission of diseases, and the environmental illnesses linked to changes in ecosystems.
A Review on the Concept (Challenges and Opportunities) of One Health Approach...BRNSSPublicationHubI
This document discusses the challenges and opportunities of a One Health approach to controlling emerging and re-emerging zoonotic diseases. It outlines that zoonotic diseases are infectious diseases transmitted between animals and humans. While the One Health approach promotes cross-sectoral collaboration, challenges include difficulties in collaborative work across disciplines due to differences in approaches and a lack of standardized frameworks. Socio-political challenges also exist from public beliefs and rights issues. Ethical concerns regarding secure data distribution and wildlife management further impact One Health implementation. However, solving these challenges could make One Health a powerful tool for disease protection globally.
Global climate change is increasing the prevalence and severity of bacterial diseases by altering ecosystems in ways that benefit disease-carrying organisms. Rising temperatures expand suitable habitats for disease vectors like mosquitoes and ticks, allowing diseases to spread into new areas. Climate change also influences disease transmission cycles - for example, some parasites now complete their life cycles faster. These changes are having significant impacts, including the potential introduction of new parasites into freshwater ecosystems like the Great Lakes, posing health risks to both wildlife and humans. Effective monitoring and predictive modeling are needed to understand and address how climate change continues to influence infectious diseases worldwide.
The document discusses biodiversity and its impact on human health and society. It begins by stating that wildlife decline is projected to be 67% by 2020 due to human population growth and habitat destruction. Loss of biodiversity can harm ecosystems and their stability. Various threats to biodiversity are discussed such as habitat loss, overexploitation, and pollution. Consequences of biodiversity loss include negative impacts on nutrition, health, and increased environment-related illnesses as ecosystems become less able to regulate diseases. Maintaining biodiversity is important for human well-being and health.
Biodiversity refers to the variety of plant and animal life in a particular habitat. It is essential for healthy ecosystems and human well-being. Loss of biodiversity can negatively impact food/water security, medicine development, business/livelihoods, and protection from disasters. The main threats are habitat loss, pollution, overexploitation, invasive species, and climate change. Preserving biodiversity is crucial to ensure continued ecosystem services and human health.
This document discusses emerging and re-emerging infectious diseases. It defines emerging diseases as newly identified infectious agents and re-emerging diseases as previously known agents that are increasing in incidence after being controlled. Factors that contribute to emergence include evolution of pathogens, human behavior and demographics, environmental changes, and weaknesses in public health systems. Examples of emerging diseases discussed are hepatitis C, zoonoses, and pandemic H1N1 influenza. Examples of re-emerging diseases include diphtheria, cholera, plague and dengue fever. Public health responses outlined include surveillance, investigation and control measures, prevention efforts, and global networks like GOARN that facilitate international outbreak response.
Fungal diseases have a significant economic and health impact globally. Over 600 fungal species are associated with humans, some as commensals and others as pathogens causing lethal infectious diseases. Individuals with weakened immune systems are most at risk, but emerging fungal diseases also threaten healthy individuals. While few fungi can thrive in human bodies at normal temperatures, immunocompromised individuals are susceptible to opportunistic fungal infections. Fungal diseases also afflict animals and plants worldwide, threatening biodiversity, agriculture, and livestock. Rust and smut fungi in particular cause major economic losses in cereal crops. Effective control of fungal diseases requires more research and reporting of cases.
Foodborne diseases pose a significant threat to public health worldwide. They can be caused by bacteria, viruses, parasites or toxins entering the body through contaminated food. Major pathogens like Salmonella, E. coli and Campylobacter cause foodborne infections and intoxications with symptoms like diarrhea and vomiting. In developing countries, poor hygienic practices and lack of surveillance exacerbate the foodborne disease burden. Proper food safety practices and surveillance systems are needed to reduce illnesses and deaths from these preventable diseases.
Similar to Animal disease ecology and transmission by Dr. C Domingo (20)
- Native pigs have a higher digestive capacity and microbial activity in their hindgut compared to improved pigs, allowing them to utilize low-quality feed materials.
- General feeding practices for native pigs include feeding a combination of concentrate and forage twice daily. Feeding practices vary based on life stage from sows and boars getting 1-1.5kg of mixed feed and supplements, to suckling piglets getting ad-libitum starter mash and supplements, to weaners getting 0.3-1kg of mixed feed and supplements.
- Sample mixed feeds for native pigs contain ingredients like rice bran, corn, copra, and molasses. Establishing forage production areas can help minimize feed

This document discusses native pig farming in the Philippines. It begins by outlining the demand and consumption of pork in the country. It then provides details on marketing the native pig, including potential products (lechon), target markets (lechon consumers), and pricing. The document also analyzes the costs and returns of raising native pigs, including feed costs, sales projections, and estimated profits from selling weanlings and slaughter pigs (lechon-type). In summary, the document finds that native pig farming in the Philippines can be a profitable endeavor.
Health care in native pig production (dr. aleli a. collado)Perez Eric
This document discusses herd health programs for native pig production. It outlines the epidemiologic triad and describes key elements of a herd health program including biosecurity, vaccination against hog cholera, and control of internal and external parasites. Common diseases of pigs are also listed, along with signs of unhealthy animals and preventive measures. First aid recommendations for diarrhea, fever and colds in pigs are provided.
Breed development, production and commecial utilization of native pigsPerez Eric
- Native pigs are an important part of rural farming communities in the Philippines, providing food security, income, and cultural/social roles. However, native pig production typically remains a small-scale backyard activity without consistent profits.
- There is increasing demand for organically and naturally produced foods, as well as interest in conserving native genetic resources. Improved native pig breeds are desired that are adapted to local conditions but also provide uniform, predictable production and product quality.
- A strategy is proposed to develop homogeneous but genetically diverse native pig populations through organized breeding programs, improved production systems, and marketing of native pig products.

It outlines the value of native pigs in providing income and food for rural families as they are resilient to climate extremes. It describes strategies to establish more homogeneous native pig populations through selection while maintaining genetic diversity. This includes establishing true-to-type breeding populations to meet producer and consumer preferences for consistent quality and performance. Research demonstrates improvements in birth weight, 6-month weight and litter size through selection. Native pig production is shown to provide net income for farmers with the right management.
Science-based native pig production to meet quality requirements of native pi...Perez Eric
This document summarizes the presentation of Fabian Maximillan B. Cabriga on science-based native pig production in the Philippines. It discusses the current situation of small-scale native pig farmers, including issues like lack of training, standards, and market support. It then outlines how the Philippine Native Pig Owners Network Association was established in 2015 to address these issues. The association has helped organize farmers, establish stable prices, and promote native pork. It also describes Teofely Nature Farms, a model native pig farm started by Cabriga, and how it aims to produce high quality native pork and vegetables sustainably through good practices.
Benefits and Market Potential of Native Pig Lechon Processing and MarketingPerez Eric
Lechon, or roasted pig, is a Filipino delicacy traditionally made with native Philippine pigs. The document discusses lechon production in La Loma, Philippines, which is considered the lechon capital. Ping Ping Native Lechon & Restaurant is one of the established brands in La Loma that uses 100% native pigs for lechon. While there is steady demand, production is limited by the supply and high costs of quality native pigs. The lechon industry needs government support to address issues around native pig supply and transportation regulations.
Native Pig Trading and Lechon Processing and Marketing in CebuPerez Eric
Ms. Claire C. Silva owns Claire's Lechon de Cebu, which began in 1989 processing one pig per week and has since expanded to processing 10-15 pigs per week normally and up to 40 pigs on weekends during peak seasons. Native pigs from Negros and Bohol are used for their juicy and tasty meat. The pigs are slaughtered and seasoned in-house before being roasted over open wood charcoal. While lechon production has grown, challenges include fluctuating pig prices and quality as well as competition from other processors. Future plans include breeding their own pigs and expanding markets.
The document summarizes a FIESTA event held in Zamboanga City to promote the ZamPen native chicken breed. It discusses the 10 years of research that went into developing the ZamPen breed. The event featured exhibits, forums, and competitions to encourage local farmers and businesses to raise ZamPen chickens as a livelihood option. The goal was to connect producers with potential buyers and introduce technology that can help the native chicken industry. Samples of dishes made from ZamPen chicken were served to event attendees.
The FLS-GEM project trained over 2,500 goat farmers through 28-week courses focusing on improved feeding, breeding, health and waste management. This led to increases in productivity such as higher conception rates, shorter kidding intervals, and greater survival rates and kid weights. Farmers saw higher profits as a result, with income increasing by over 30% on average. The project had wide social impacts as well, with increased cooperation between farmers and new businesses developing around goat farming. The project was so successful that its training model was adopted as the national standard for goat production in the Philippines.
The document discusses an e-learning program on goat raising offered by the DOST-Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development (PCAARRD). The program offers free online certificate courses on topics related to goat production. As of November 2017, over 2,100 students have graduated from the program, consisting of farmers, extension workers, businessmen, and overseas Filipino workers. Students can enroll by creating an account on the e-extension website and selecting from the available goat raising course modules.
The document discusses the Test-Interval Method (TIM), a common practice for measuring total milk yield (TMY) in small ruminants. TIM uses a formula that calculates TMY based on milk measurements taken at intervals after birth and between subsequent milkings. It originated as a way for farmers and organizations to evaluate goat performance and rank animals for selective breeding programs to improve genetics. TIM can be used on individual farms or in government programs.
This document discusses standards for slaughtering and cutting goats. It outlines proper procedures for transporting goats to slaughter, ante-mortem and post-mortem inspection, and slaughter methods. Detailed cutting schemes for six prime cuts of chevon are also presented. Adopting these standards would help produce clean meat through proper hygiene, allow for higher carcass recovery, demand higher prices, and serve as a guideline for developing policies around goat slaughtering.
The document summarizes research on a herbal dewormer called MCM for goats. MCM is created from a mixture of three Philippine plants - makahiya, caimito, and makabuhay. Clinical trials showed MCM, administered as either a 500mg capsule or 500ul liquid twice at a 2 week interval, was effective at eliminating the parasitic roundworm Haemonchus contortus in goats. This led to increased health, milk and meat production in treated goats. The document provides details on the formulation, dosage, availability and pricing of the herbal MCM dewormer and encourages farmers to try and support this natural treatment option for healthier goats.

Animal disease ecology and transmission by Dr. C Domingo
1. Animal Disease Ecology and Transmission
Clarissa Yvonne J. Domingo, Dr.PH
For a start, there is a need to define important terms. There are two terms that
are always interchanged and these are “infection” and “disease”. To differentiate,
infection implies the presence of a pathogen in the body but does not necessarily
mean the presence of clinical signs whereas disease relates to the occurrence of cases
and outbreaks (with clinical signs) caused by the pathogen in a population. Other terms
are ecology which is defined as the branch of biology that deals with the relations of
organisms to one another and to their physical surroundings. On the other hand,
transmission is the passing of a communicable disease from an infected host
individual or group to a particular susceptible individual or group. The succeeding
information describe the interplay of environmental conditions, the animal, invertebrate
vectors and the pathogen that leads to disease transmission.
At a macro level, growing populations, income gains and urbanization have made
livestock one of the fastest growing subsectors of agriculture. Developed countries have
experienced impressive agricultural expansion which has been associated with a
widespread transformation of the livestock sector. However, as a result of globalization
and climate change the world is currently facing an unprecedented increase of
emerging and re-emerging animal diseases and zoonoses (animal diseases
transmissible to humans). Environmental conditions have profound influences on animal
productivity and production, distribution of many endemic animal diseases, especially
those transmitted by biological vectors (e.g. insects and snails), and up surge of
emerging diseases. Livestock is important in supporting the livelihoods of smallhold
farmers, traders and laborers throughout the developing world. Hence, diseases
affecting livestock can have a devastating impact on animal productivity and production,
on trade in live animals, meat and other animal products, on human health and,
consequently, on the overall process of economic development.
Ecological factors involved in or contributing to disease emergence and re-
emergence and spread include both biological and abiotic factors.
Biological factors
1. Environmental, climate, weather changes (temperature and humidity).
The environment, specifically climate, greatly affects agricultural and livestock
production. Climate influences the availability of pasture and forage crops as well as
the distribution of diseases and pests. The health resistance of animals is also
dependent on temperature and humidity. A climate-normal condition is the average
climate conditions during a period of 30 years in a given region. Evident effects of
climate change are flooding and drought, loss of habitats and ecological niches, and
1
2. change in livestock-agricultural production systems. Losses due to climate change in
the year 2000 were estimated to be USD 40 billion.
Climate change also has the following effects on disease occurrences:
• Increased parasitic zoonoses (helminthoses, tick-borne diseases).
• Increased spread of vectors and vector-borne diseases (e.g. Rift Valley fever, West
Nile virus).
- Increased humidity increases vector survival; increased rain may increase larval
habitat and vector population size by creating new habitat
• Increased incidence of tropical diseases in areas previously considered as having
temperate climate conditions (e.g. Old and New World screwworm).
• Alteration of disease eco-epidemiology, new disease patterns, and change in vector
capacity.
- Decreased rain can increase container-breeding mosquitoes by forcing increased
water storage
- Epic rainfall events can synchronize vector host-seeking and virus transmission
• Change in geographic range, host range and pathogen virulence.
- decreased extrinsic incubation period of pathogen in vector at higher
temperature changes during transmission season; at higher temperature
changes there is decreased extrinsic incubation period of pathogen inside the
vector during transmission season
2. Ecological and ecosystem changes.
Changes in the current conditions of the ecosystem affect many animals and
cause higher risk for emergence of diseases and the occurrence of pathogens and
parasites.
3. Animal density and biomass.
The optimal density of animals in a specific location is vital to animal health.
Overcrowding or high densities pose high risks and allow faster transfer of parasites
and pests.
4. Changes in host-pathogen interactions.
The emergence and re-emergence of diseases can be attributed to host-pathogen
interactions. When these interactions are interrupted or altered, the resistance of
animals can be weakened and places them in vulnerable states.
5. Microbial adaptation (genetic drift and shift) to new environmental conditions.
2
3. The emergence of some diseases is due to the natural evolution of micro-
organisms. Resistance to the effects of anti-microbial drugs also contributes to the re-
emergence of diseases.
Intrinsic properties of the pathogens that are associated with this are:
a. such as genetic drift and shift, as it occurs in avian influenza virus;
b. conjugation, transformation, and transduction in bacteria.
c. adaptation to new vectors and hosts
Severe acute respiratory syndrome (SARS) is a viral respiratory illness,
caused by SARS-associated coronavirus, is believed to have emerged in
Guangdong, China, in November 2002. The illness spread to a global epidemic
before it was contained. According to the World Health Organization, 8,098 cases,
including 774 fatalities, have occurred. The virus has an unknown reservoir, but
wildlife is a likely source of infection. Natural infection has been demonstrated in palm
civet cats in markets and also in raccoon dogs, rats, and other animals indigenous to
the area where SARS likely originated. The live market and Restaurants in china sold
small carnivores and several species of civet cat.
d. mutation and recombination/reassortment in humans and other animals
after exposure to multiple pathogens (e.g. foodborne viruses, influenza
viruses);
e. development of increased virulence or drug resistance
6. Changes in land use and use of natural resources.
Human economic activities cause major changes in land use. Encroachment into
natural animal habitat due to forest clearings and land conversions for various uses
such as industry, pasture, residential space and agriculture bring about changes in
animal and human density and distribution. It also alters local biodiversity through the
introduction of exotic and invasive species that could cause extinction of one or more
species.
An example of this is the outbreak of Nipah virus in peninsular Malaysia in 1999,
when intensive pig farming intruded into the natural habitat of fruit bats carrying the
virus. Unidentified spillover events caused infection of the pig population which acted
as an amplifier host, eventually transmitting the virus to farmers and resulting in 105
human deaths (Field ''et al.''., 2001).
7. Increased contacts between pathogens and host population (urbanization, rural
peri urban-urban continuum)
With continuous human population growth, land available for livestock and
agriculture decreases as a result of urbanization and industrial conversion. Animals
are kept in densely populated areas. This increases the contacts between pathogens
and hosts that lead to increased exposure and risk.
3
4. 8. Social and cultural practices
Social and cultural practices of man add to the risk of zoonotic transmission.
These are:
a. food habits

Abiotic factors
1. Globalization, international trade, and level of economic development.
Globalization is driven and constrained by economic forces, technological
developments, political, cultural, social and environmental factors that impact directly
and indirectly on health at a number of levels. As globalization spreads, animals and
products that could be infected or contaminated are transported and pose a wide
range of risks that affect the emergence of diseases.
Due to globalization, changes in the movements of human and animal populations
enhance transmission. For instance, distance and speed of travel have increased
1000 fold since 1800 and there are 1.4 billion air travelers/year. Likewise, movements
are attributed to:
f. extent of ownership and movement of pets
g. extent of air travel
h. extent of ecotourism, hunting, camping, etc.
i. Introduction of infected host in to new ecosystem. eg : Marburg Disease
j. natural movement of wild animals including migratory birds, and by
anthropogenic movement of animals.
2. Lack or inadequate policies for control and confinement measures.
Policies are important in managing and implementing movement restrictions of
animals and products from one place to another, especially across borders.
Collective efforts in crafting policies should be considered that would include
important stakeholders, specifically farmers. Policies and strategies should be
improved to safeguard animal health, public health, livelihoods and food systems.
3. Political and civil strife and instability.
There is disruption of health services in war-torn or impoverished countries. The
conditions in the war-torn Kosovo led to epizootic rodent tularemia.
4. Breakdown of public services in charge of disease control.
4
5. In case of natural disasters, health infrastructures are damaged and control of
diseases that emerged from the calamity cannot be mitigated efficiently and
effectively.
5. Management of animal waste.
Due to the popularity of organic farming and intensive tilapia inland farming,
poultry manure and other animal manure became a source of added income to
livestock farmers. Transporting manure to other places because of demand is a risk
for transmitting the pathogens. Wet manure is seeded with viable viral, bacterial,
fungal and protozoal pathogens that can be harmful to both man and susceptible
animals. Manure-related fish kills which are typical in many countries are a result of
poor manure management.
6. Poor public health management.
Poor management results in lack of integration with animal health surveillance,
funding in the public health sector and sustained funding on scientific studies to
answer public health questions and build expertise.
7. Animal welfare philosophies affecting animal production system.
Animal welfare societies have been loud in espousing practices that should not
hinder the natural behavior of animals. Due to increase practice of range farming
however, soil-borne parasites that have been controlled before occurred such as
Trichinella , Toxoplasma, cysticercosis, etc. have re-emerged.
8. Changes in production systems.
Production systems are shaped by prevailing biophysical and socio-cultural
environments. In many of these systems, the livestock element is interwoven with
crop production, as in rice-buffalo or cereal-cattle systems in Asia. Many of these
systems are currently under pressure to adjust to rapidly evolving socio-economic
conditions and large intensive livestock production units. Increasing demand for
animal protein has led to changes in:
a. farming practices (e.g. large “open” poultry production units in Asia)
b. animal markets
c. bush meat consumption
d. global trade
In particular, pig and poultry production have emerged over the last decades in
many developing regions in response to the rapidly growing demand for livestock
products. With the world human population constantly increasing since 1960,
especially in developing countries, it is expected that food demands will likewise
5
6. increase. Projections from 1961 to 2020 showed that demand will increase
dramatically to around 400 million tons of milk in developing countries. Likewise,
meat demands from both monogastric and ruminants from these areas will also
increase by 2020 to more than 160 million tons, with greater emphasis on
monogastric meat (Figures 1, 2 and 3).
A large shift in annual growth rates of production systems to industrial systems
is also seen in Asia at more than 15 percent as compared to Sub-saharan, West
Asia, North Africa, and Central and South America. Asia still leads, with mixed
systems at less than 5 percent. However, a decrease of 5 percent in grazing
systems in Asia is evident. West Asia and North Africa take the lead for grazing
systems (Figure 4).
The intensity of production poses risks to the emergence of zoonoses. As the
intensity of production increases, there is greater complexity and severity of
diseases.
6
7. One example of emerging zoonoses is bovine spongiform encephalopathy
(BSE), which rapidly evolved into an issue of major public concern in 1996. This
disease crossed the species barrier and infected humans in the UK. The European
Geographical BSE Risk Analysis (GBRA Figure 5).) basic assumption is that the BSE
agent is initially introduced into a country's domestic cattle production system through
the importation of contaminated feedstuffs or live cattle. The GBRA showed that a
majority of countries in Europe had a high risk of BSE, followed by North America
(Figure 6).
In the case of BSE, and looking at the trend of using cereals as feed in
different countries and regions, China is projected to dramatically increase its use
of cereals by 2020, reaching 178 million MT, which is more than double its usage
7
8. in 1993. Latin America is also seen to have increasing use of cereal feeds. These
increases could pose high risk of emergence of BSE that should be closely
monitored (Table 1).
Macro-environment and diseases
The macro-environment can influence the pattern of disease events. Extreme
conditions of the physical environment such as climate, topography, vegetation and soil
can directly cause illness or disease to animals. Factors affecting pathogen vectors,
endemicity, and pathogen vector diffusion include temperature, relative humidity,
vegetation cover and plant species and chemical composition of soils.
These macro-environment factors could be significant in determining distribution
of gastrointestinal parasites, as external temperature affects the transformation of eggs
of parasites in L1, L2 and L3. At temperatures of less than 10 C, the process is⁰
prolonged, while at greater than 25 C, process is rapid but with high L3 mortality. Acid⁰
or base soils can affect the survival of eggs and larvae of gastrointestinal parasites.
Retrospective analysis of meteorological data, including wind direction, explained the
spatial distribution of bluetongue transmitted by Culicoides in sheep in Turkey.
The distribution of tsetse flies in Africa is governed by macro-environment
factors. Temperature, humidity and vegetation cover were used to map the distribution
of tsetse fly vectors. The presence of the tsetse fly in each vegetation cover could be
determined and later combined for final mapping.
More detailed predictive parameters can be used in the analysis to determine
areas under disease risk. Aside from the macro-environment factors, epidemiological
and socioeconomic factors could be integrated for a more refined mapping output of
disease risk areas (Table 2).
8
9. Predicting the presence of disease using a set of parameters could accurately
model the observed disease situation in a certain area. Predictive mapping could be
useful for the management control planning in a large area (Figure 7).

10. Micro-environment and diseases
Micro-environment also plays an important role in the emergence of diseases.
Microenvironment involves the interaction between biological supports (host animal,
vector, and pathogen), which determine the establishment, multiplication, spread or
reduction, and even elimination of infections.
Capacity of a host to respond to infectious attack:
• Susceptibility. The ability to acquire a pathogen and to show a pathological status.
• Tolerance. The relative capacity to control the development of a pathogen and to
limit its pathological effects.
• Resistance. The ability to reduce the growth rate, fecundity, and persistence of a
population of pathogens.
• Resilience. The ability to grow and be productive despite the presence of a normal
pathogen charge.
• Refractoriness. The impossibility to acquire an infection because the biological
support inhibits the multiplication of the pathogen.
Micro-environmental interactions and competitions:
• Coccidia and helminths: There is equilibrium at the level of the gastrointestinal
track. Treatments against coccidia positively affect the multiplication of
gastrointestinal helminths and vice versa.
• Tsetse flies, intestinal symbionts and trypanosome infections: There are symbiotic
micro-organisms (Wigglesworthia glossinidia) that confer a degree of immunity to
the tsetse fly to acquire and transmit trypanosome infections.
Economic impact of main parasitic diseases
Many parasitic diseases worldwide have caused great economic losses. Ticks
and tickborne diseases (Amblyomma, Hyalomma, Rhipicephalus, Boophilus,
Anaplasmosis, Babesiosis, Theileriosis, heartwater) in cattle cost an estimated USD 15-
20 billion. Gastrointestinal parasites (Paramphistomum, Haemonchus, Ostertagia,
Trychstrongylus, Cooperia, Strongyloides, Oesophagostomum) put at risk 300 million
10
11. bovines and 250 million sheep; mortalities and decreased productivity amounted to an
estimated USD 3 billion.
Tsetse transmitted trypanosomosis (T. congolense, T. vivax, T. brucei ) in Africa
put at risk 60 million cattle with a mortality rate of 3 million cattle each year; 40 million
doses of trypanocides are used annually while livestock; agricultural production losses
are estimated at USD 4.5 billion. Non-tsetse transmitted trypanosomosis (T. evansi and
T. vivax) in Asia and Latin America caused losses in the range of hundreds millions of
US dollars.
Interventions to improve livestock and agriculture production systems require
policies that address many aspects. Successful control and management of a specific
disease includes interventions in socio-economic dimensions, institutional support,
training and information, land use, land tenure, and natural resource management, and
increasing agricultural production (Figure 8).
