Effects of probiotic supplementation in rations containing leubiem fish waste (Chanthidermis maculatus) on the performance of local ducks

Abstract

Abstract The aim of this study is to determine the effect of probiotic supplementation in rations containing leubiem fish waste (Chanthidermis Maculatus) on the performance of local duck. The study used 192 female local ducks 8-20 weeks old grower phase. The ducks were allocated into 4 treatments and 4 replications (12 ducks/pen). The female local ducks was fed ration contained 18% crude protein and 2700 kcal/kg metabolizable energy. The experiment used completely randomized design with 4 treatment rations: P1 (basal diet/control); P2 (probiotic supplementation 0,5% in rations containing 10% leubiem fish skin flour); P3 (probiotic supplementation 1% in rations containing 10% leubiem fish head flour); P4 (probiotic supplementation 1,5% in rations containing 10% leubiem fish bone flour). The observed variables were: feed consumption, body weight gain, final body weight, feed conversion, and mortality of local duck. Data were analiyzed by one-way analysis of variance then continued with Duncan test. The results showed that of probiotic supplementation in rations containing leubiem fish waste gave a positive response to the performance of female local duck grower phase. Probiotic supplementation in rations containing leubiem fish waste (skin flour, head and bone) significantly affect (P<0,05) feed consumption, body weight gain, final body weight, and ration conversion, but no significant affect on mortality local duck grower phase. It was concluded that of probiotic supplementation 1% in rations containing leubiem fish waste (skin flour 10%) could to increase body weight gain, final body weight and be able to reduce local duck mortality.
