Abstract

Crude protein needs of chickens have changed due to genetic line differences and selection of those lines for differing broiler traits. Standard commercial broiler strains have been selected to be used to meet multiple processing categories typically at live body weights less than 3.5 kg. In the last two decades high-yielding broiler strains were introduced into the commercial market. These breeds are known as the Cobb 700 and Ross 708. The works included within are focused on the Cobb 700 high-yielding broiler strain, and its response to crude protein, with emphasis on digestible lysine.
