HPAI outbreaks tend to be self-limiting as few birds survive to act as carriers. Diagnosis involves hemagglutination inhibition and immunodiffusion tests. Prevention focuses on vaccination and treating flocks with antibiotics to control secondary infections.
This document discusses Newcastle disease, a highly contagious and destructive viral disease of birds. It is caused by a paramyxovirus that can infect all bird species and some mammals. The virus exists in lentogenic, mesogenic, and velogenic pathogenic forms. Clinical signs vary depending on the strain but often include respiratory signs such as coughing as well as nervous signs such as tremors. The disease is transmitted through direct contact or contaminated feces, equipment, feed, and wild birds. Young birds are generally more severely affected. Vaccination is important for control of this economically important disease of poultry.
Pseudorabies is an acute, frequently fatal disease with a worldwide distribution that affects swine primarily and other domestic and wild animals incidentally. The pseudorabies virus has emerged as a significant pathogen in the USA since the 1960s, probably because of the increase in confinement swine housing or perhaps because of the emergence of more virulent strains. Clinical signs in nonporcine animals are similar to those of rabies, hence the name “mad itch” (pigs do not display this sign). Pseudorabies is a reportable disease and has been successfully eradicated from the vast majority of the USA.

Malignant catarrhal fever (MCF) is an infectious systemic disease that presents as a variable complex of lesions affecting mainly ruminants and rarely swine. It is principally a disease of domestic cattle, water buffalo, Bali cattle (banteng), American bison, and deer. In addition to these farmed animals, MCF has been described in a variety of captive ruminants in mixed zoologic collections.MCF results from infection by one of several members of a group of closely related ruminant gammaherpesviruses of the Rhadinovirus genus.
Newcastle disease (ND) is a viral disease affecting wild and
domestic birds. It is characterized by a high variability in
morbidity, mortality,
ND primarily affects chickens and turkeys, but most poultry
and many wild and domestic birds are susceptible.
Infectious laryngotracheitis is a highly contagious respiratory disease of chickens caused by an alpha herpes virus. It results in severe breathing difficulties and coughing due to laryngitis and tracheitis. The virus can survive for weeks in the environment and is transmitted between flocks through contaminated equipment, litter and people. Clinical signs include eye discharge, coughing and the expectoration of blood from the trachea. Prevention relies on vaccination of chickens with modified live vaccines starting at 2-4 weeks of age.
Rinderpest, also known as cattle plague, is a highly contagious and deadly viral disease affecting cattle and other cloven-hooved ruminants. It is characterized by fever, sores in the mouth, diarrhea, and high mortality rates. The virus is transmitted between animals through direct or indirect contact with secretions from infected hosts. While rinderpest has been eradicated globally through vaccination and control programs, it was once a severe problem affecting livestock in Africa and Asia. Treatment is ineffective but the disease can be controlled through quarantine, vaccination, and hygiene measures.

Astroviruses are small, star-shaped RNA viruses that infect the intestinal tract of young birds. They are a common cause of runting-stunting syndrome in broilers and enteritis in guinea fowl. Six different types of avian astroviruses have been identified that infect chickens, turkeys, and ducks. Astroviruses are transmitted orally and cause mild intestinal signs but can also lead to more severe disease if other pathogens are present. Diagnosis is made through electron microscopy, ELISA, or PCR techniques. There is no vaccine or treatment available, so control relies on good hygiene and management practices.
Rinderpest virus is a Morbillivirus, closely related to the viruses causing peste des petits ruminants, canine distemper and measles.Rinderpest virus is shed in nasal and ocular secretions and can be transmitted during the incubation period (1–2 days before onset of fever). Transmission required direct or close indirect contact between susceptible animals and sick animals shedding the virus.
Common respiratory diseases that affect the airways and lungs of poultry include fowl pox, Newcastle disease, infectious bronchitis, avian influenza, infectious coryza, infectious laryngotracheitis, and chlamydiosis. Fowl pox causes wart-like lesions and can obstruct the airways, while Newcastle disease causes respiratory distress and high mortality. Infectious bronchitis primarily infects chickens and causes drops in egg production. Avian influenza and infectious coryza can cause respiratory distress in poultry. Infectious laryngotracheitis causes difficulty breathing and coughing in chickens. Chlamydiosis affects multiple bird species and can cause nasal discharge, weakness, and
Infectious laryngotracheitis (ILT) is a highly contagious herpesvirus infection of chickens and pheasants that causes respiratory signs such as coughing, gasping, and rales. The virus spreads through direct contact or contaminated equipment/litter and causes lesions in the trachea and conjunctivitis. Clinical signs range from mild to severe depending on the strain, and mortality can reach 50% in adults. Diagnosis involves identifying lesions and detecting viral DNA. Control is achieved through biosecurity measures and vaccination with live attenuated or recombinant viral vector vaccines.

Similar to Newcastle disease outbreak in region III by Dr E Lapuz (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

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.
Embracing Deep Variability For Reproducibility and Replicability
Abstract: Reproducibility (aka determinism in some cases) constitutes a fundamental aspect in various fields of computer science, such as floating-point computations in numerical analysis and simulation, concurrency models in parallelism, reproducible builds for third parties integration and packaging, and containerization for execution environments. These concepts, while pervasive across diverse concerns, often exhibit intricate inter-dependencies, making it challenging to achieve a comprehensive understanding. In this short and vision paper we delve into the application of software engineering techniques, specifically variability management, to systematically identify and explicit points of variability that may give rise to reproducibility issues (eg language, libraries, compiler, virtual machine, OS, environment variables, etc). The primary objectives are: i) gaining insights into the variability layers and their possible interactions, ii) capturing and documenting configurations for the sake of reproducibility, and iii) exploring diverse configurations to replicate, and hence validate and ensure the robustness of results. By adopting these methodologies, we aim to address the complexities associated with reproducibility and replicability in modern software systems and environments, facilitating a more comprehensive and nuanced perspective on these critical aspects.

Measuring gravitational attraction with a lattice atom interferometerSérgio Sacani
Despite being the dominant force of nature on large scales, gravity remains relatively
elusive to precision laboratory experiments. Atom interferometers are powerful tools
for investigating, for example, Earth’s gravity1
, the gravitational constant2
, deviations
from Newtonian gravity3–6
and general relativity7
. However, using atoms in free fall
limits measurement time to a few seconds8
, and much less when measuring
interactions with a small source mass2,5,6,9
. Recently, interferometers with atoms
suspended for 70 s in an optical-lattice mode fltered by an optical cavity have been
demonstrated10–14. However, the optical lattice must balance Earth’s gravity by
applying forces that are a billionfold stronger than the putative signals, so even tiny
imperfections may generate complex systematic efects. Thus, lattice interferometers
have yet to be used for precision tests of gravity. Here we optimize the gravitational
sensitivity of a lattice interferometer and use a system of signal inversions to suppress
and quantify systematic efects. We measure the attraction of a miniature source mass
to be amass = 33.3 ± 5.6stat ± 2.7syst nm s−2, consistent with Newtonian gravity, ruling out
‘screened ffth force’ theories3,15,16 over their natural parameter space. The overall
accuracy of 6.2 nm s−2 surpasses by more than a factor of four the best similar
measurements with atoms in free fall5,6
. Improved atom cooling and tilt-noise
suppression may further increase sensitivity for investigating forces at sub-millimetre
ranges17,18, compact gravimetry19–22, measuring the gravitational Aharonov–Bohm
efect9,23 and the gravitational constant2
, and testing whether the gravitational feld
has quantum properties24.
