[Studies on the use of wheat rich in crude proteins in the feeding of broilers. 2. Carcass yields and carcass composition].

Studies were made to investigate whether the the substitution of maize for high-protein wheat fed in combination with different protein in fattening rations to broilers would influence the carcass yields and chemical carcass composition of broilers. The described dietary regime was not found to have a significant influence on the different criteria of carcass composition (roaster carcass, flesh, abdominal fat, total proportion of utilizable parts) with the exception of the relative proportion of utilizable offals. The chemical composition of the total body and of all the utilizable parts showed little variation with the different types of feeding. The fat content of all the utilizable parts was much more dependent on the carcass weight of the birds at the end of the fattening period than on the composition of the rations (type of cereals used; supplementation of amino acids).
