A study on the use of Zinc bacitracin antibiotic (ZnB) and dried Morinda citrifolia waste as feed additive in broiler ration was conducted. Two hundred and sixteen day old chicks (DOC) was allocated into 4 treatments: control; control + 50 ppm ZnB, and control + M. citrifolia waste at 2 levels (5 and 10 g/kg ration) with 9 replications. Each replicatation consist of 6 birds. The treatments were allocated in a completely randomized design. Variables measured were feed intake, live weight, feed conversion ratio (FCR), percentages of carcass and internal organs (liver, gizard, abdominal fat, and thickness of intestine). The results showed that feed intake of M. citrifolia waste was significantly (P0.05) from that of control. The use of M. citrifolia waste (5 and 10 g/kg) gave significantly lower (P0.05), but was significantly lower (P0,05) than that of control, control + antibiotic ZnB and M. citrifolia waste 5g/kg. It is concluded that the supplementation of M. citrifolia waste (5 g/kg) could substitute ZnB to improve feed eficiency in broiler ration. |
