Composition of feather and offal meal and its value as a protein supplement in the diet of broilers

摘要: Two experiments are described in which feather and offal meal was included at levels of 0, 3.4, 6.8, 10.2, 13.6 17.0% the diet broilers. The used to replace Peruvian fishmeal as main protein source, highest level replacing all fishmeal. The poorer lysine methionine content but richer cystine than fishmeal. batches were relatively homogeneous when assessed by chemical analysis had metabolisable energy contents 3350 3340 kcal/kg, respectively. Feed intake depressed 17% inclusion first experiment 13.6% second experiment. The data from both showed an optimum efficiency feed utilisation about 10% broiler diets.
