Dear Dr. Rose, in my opinion, the nutritional requirements reported by genetic companies are for healthy and stress-free animals and the ideal protein profile may vary in the order of limiting amino acids, for example, an animal challenged with enteritis may have a higher threonine requirement. For the main component of the intestinal mucosa and a viral disease can increase the needs of arginine, ...

A comprehensive study and an excellent research investigation.

Oscar Briceño these are excellent questions! I must admit these details are still largely unknown. As the immune response is specific to different stressors, (e.g. heat stress vs necrotic enteritis vs respiratory virus infections) the ideal nutrient requirements for a bird exposed to those stressors is likely also varied. To answer these questions we must focus research to understanding the spec ...

For Rose, my point is that your work has shown that reducing crude protein in feed is not as simple as it may seem. This is because factors such as immune challenge and environmental stress, such as high temperature, are factors that alter the relationships of some essential amino acids with lysine, highlighting the dynamic character of the ideal protein. This detail reveals that in order to obtai ...
