This study proposes to undertake participatory/action research to understand the challenges and limitations that constrain effective Newcastle disease (ND) control among village rural poultry in Uganda. Village poultry is one of those abundant assets for the rural poor in Uganda that could be utilized to eradicate poverty in the country addressing the needs of the underprivileged in society esp...
There is growing concern with regard to the continued emergence of antibiotic resistant bacteria, which pose a significant risk to both human and animal health. Antibiotics have been used as therapeutic agents in agriculture since the 1940 s and in subtherapeutic doses as food additives to improve feed conversion of livestock and domestic poultry since the 1950's. However, the use of antibiotic...
Understanding interactions between animals and humans is critical in preventing outbreaks of zoonotic disease. This is particularly important for avian influenza. Food animal production has been transformed since the 1918 influenza pandemic. Poultry and swine production have changed from small-scale methods to industrial-scale operations. There is substantial evidence of pathogen movement betwe...
The Canadian poultry production industry contributes nearly $10 billion to the Canadian economy and employs nearly 50,000 workers. However, modern poultry facilities are highly contaminated with airborne dust. Although there are many bioaerosols in the poultry barn environment, endotoxin is typically attributed with the negative respiratory symptoms observed in workers. These adverse respirator...

Furthermore, there are a number of consumer concerns regarding the use of antibiotics in food animals including residue contamination of poultry products and antibiotic resistant bacterial pathogens. These issues have resulted in recommendations...
Poultry industry has always been a dynamic and integral part of national economies in many countries. Economic losses incur especially in large-scale rearing facilities, often attributed to the deterioration of environmental conditions, poultry exposure to stressors and development of diseases. While antibiotics have been commonly used for prophylactic purposes and as growth stimulants, extensi...
Poultry litter is a valuable nutrient source for crop production. Successful management to reduce ammonia and its harmful side-effects on poultry and the environment can be aided by the use of litter amendments. In this study, three acidifiers, two biological treatments, one chemical urease inhibitor and two adsorber amendments were added to poultry litter. Chemical, physical and microbiologica...
