In an experiment designed to test the effect of different protein and energy treatments on body mass restriction of broiler breeder pullets, carcass analyses were carried out on these birds at 3 different stages during the growing period. None of the dietary treatments was successful in limiting body mass at a desirable level. Body fat content was found also to be in excess of a desirable level. Although significant differences in body fat and water content were noted, body fat content was related to the energy intake of the diet, being lower in birds on low energy or high protein diets where the intake of energy was relatively limited, Further research is needed in order to ascertain to what extent body mass and percentage carcass fat should be limited in order to improve reproductivity.
