Data are presented to demonstrate the realistic genetic response expected per generation at both the broiler and parent stock level for the most economic important traits. The greatest economic gains are made at the broiler level as opposed to the parent level. It is also demonstrated that a positive response for egg numbers will negatively influence the more economic important broiler level traits, such as growth rate and a high degree of fleshing. Data presented show that a subjective score of body conformation (fleshing) can accurately be utilized for increasing the percentage dressed carcass weight (yield) of live broiler weight.
