Characterisation of the response of male broiler chickens to diets of various protein and energy contents


, : Characterisation of the response of male broiler chickens to diets of various protein and energy contents. British Poultry Science 23(6): 527-537

The regression of bodyweight gain in chicks up to 3 weeks old on the linear and quadratic effects of dietary energy and protein contents accounted for about 50% of the observed variation. The same model accounted for only 18% of the variation in feed intake, but 68% of the variation in feed utilization (feed/gain ratio). Including initial bodyweight in the bodyweight gain model increased the explained variation from 50 to 65% of the observed variation.
