ABSTRACT
Two experiments were conducted to determine the nutritional value of hominy feed and impact of an enzyme preparation in broiler chickens diets. In the first experiment, 480 one-day-old chickens were fed 6 experimental diets (treatments) from the day of hatching to 35 days of age with increasing quantities of hominy feed replacing 0, 50 and 100% of maize. The diets were fed with or without enzyme supplementation. Each treatment consisted of 10 replications, 8 birds per replication. During the entire period, chickens from the group receiving maize had a lower (P<0.05) feed conversion ratio (FCR) in comparison with other experimental groups. Body weight gains were also reduced (P<0.05) when maize was substituted by hominy feed. Addition of enzymes improved FCR (P<0.05). Experiment two was carried out using 120, 21-day-old Ross male chickens in 10 treatments, 12 birds per experimental group. Birds fed maize hominy diets had the lowest organic dry matter and N-free extractives apparent digestibility coefficient (P<0.05). Hominy diets also had a lower AMEN value (P<0.05). Enzyme addition improved the apparent digestibility of all nutrients (P<0.05) except crude fat.
