Respon Broiler Terhadap Penambahan Probiotik EM4 Dalam Air Minum

Abstract

The aimed of this experiment to determine the effect of addition probiotic EM₄ in drinking water to performance and percentage of carcass weight broiler. The research method are experiments using completely randomized design (CRD), consisted 4 treatments R0 (drinking water + 0% probiotic EM₄), R1 (drinking water + 5% probiotic EM₄), R2 (drinking water + 10% probiotic EM₄), R3 (drinking water + 15% probiotic EM₄), with 6 replications. The parameters observed in this study were: feed consumption (g/tail), drinking water consumption (ml/tail), weight gain (g/tail), ration conversion and percentage of carcass weight (%).The results showed that the addition of probiotics EM₄ in drinking water up to 15% gave no significant effect (P>0.05) on feed consumption, weight gain, ration conversion and percentage of carcass weight. Based on the calculation of the total feed consumption of broiler during the experiment ranged from 2561.54 g/tail up to 2587.63 g/tail, the body weight gain during the experiment ranged from 927.33 g/tail up to 966.50 g/tail, the ration conversion during the experiment ranged from 2.61 up to 2.81 and the percentage of carcass weight obtained ranged from 63.03% up to 65.59%. While the addition of probiotics EM₄ in drinking water up to 15% gave a significantly different effect (P<0.01) on drinking water consumption of broiler. The highest drinking water consumption are on treatment R0 (drinking water + 0% probiotic EM₄) ie equal to 3355.38 ml/tail and the lowest drinking water consumption are on treatment R3 (drinking water + 15% probiotic EM₄) ie equal to 3062.38 ml/tail.
