Appetite genes are key to better diets for poultry, study shows
Date:3/26/2013

lso affected the chicken's natural body weight.

Their findings back up the theory that, when poultry were domesticated thousands of years ago and bred for increased size, their appetite levels were changed. The study could also help inform research looking at appetite regulation in other animals.

Dr Dunn said: "All species regulate their appetites to make sure the amount of food taken in is just the right to maintain body weight and fat content. Our research has shown that there is genetic variation in the interpretation of biological signals sent relating to being full. This also affects what would be considered to be the natural body weight of chickens."
