Tryptophan is an essential amino acid, which is the building block of protein, therefore it cannot be synthesized by the body itself and must be obtained through food; it is important for many metabolic functions. A tryptophan deficiency could affect behavioral responses to stress in poultry.
Human-animal interaction is the mutual and dynamic relationship between a human and an animal where the animal perceives human interaction as degree of relatedness or distance and vice-versa. Human beings have domesticated poultry species for eggs and meat production. However, fearfulness as a trait still persists and domestic animals often perceive human encounters as fearful.
Steam or steam plus forced air heat may become an approved method to supplement ventilation shutdown during emergency depopulation of cage-free aviary laying operations, according to researchers at Michigan State University and the University of Arkansas.
On-farm hatching of broilers may be a viable option to increase efficiency by increasing hatchability and reducing total mortality during rearing, according to scientists in Denmark.

Transporting poultry from grow farms to processing plants can be stressful for birds, even more so in humid weather or during a brisk cold snap when stress levels can increase enough to contribute to weight loss and reduced meat quality.
The National Chicken Council recently developed a Q&A on vaccines to help veterinarians, producers and others involved in live production educate their families, friends and communities about their usage in poultry production.
Heat stress isn’t just for summer anymore. A 68-minute webinar with Vasil Stanev, DVM, discusses thermoregulation, heat-stress mechanisms and how to manage heat stress effectively in poultry flocks.
Sustainability associated with food-animal production encompasses environmental, economic, and social issues. Adding to the complexity is the fact that participants of the supply chain and consumers have growing influence on the food-animal sector.
Starting a conversation about a mental health challenge is a powerful way to help stop the stigma that often affects friends and colleagues struggling with a mental illness.
Commercial egg-laying operations can benefit from more effective and economical ways to depopulate flocks at the end-of-lay while improving worker performance and maintaining or improving animal welfare.
Sustainability issues demand significant attention today. And while it can be challenging to identify and implement strategies, sustainability will continue to drive decisions within the food-animal sector.
