Protein values of Omasum meal and blood-Omasun meal for broilers with maize milling waste as basal

Abstract

A total of one hundred and sixty-eight broilers of four weeks old were used to determine the protein value of omasum meal and blood-omasum meal. There were four experimental diets in which maize milling waste served as the basal diet. The broiler on the abattoir wastes (omasum meal and blood-omasum meal) had comparable (P>0.05) feed intake which were higher (P<0.05) than the intake on the milling waste diets. All the animals gained weight except for the birds fed on the omasum meal that lost 14.17g of weight. The net protein utilization of 44.69% for blood-omasum meal was comparable with those obtained on the maize milling waste diets, while those on omasum meal had a very low (P<0.05) protein utilization value of 7.65%.

Key words: Maize milling waste, omasum meal, blood-omasum meal, protein utilization.
