Synergetic effect of enzymes and probiotic in improving sorghum (<i>Sorghum bicolor</i>) based diets for broiler chickens

Abstract

The study was carried out to assess the synergetic effect of the combination of enzymes and probiotic in sorghum based diet for broiler chickens. Three hundred and ninety-six (396) Ross broiler chicks were allotted to six (6) dietary treatments with three (3) replicates, each having twenty-two (22) birds in a completely randomized design. Treatment 1, maize based diet; T2, sorghum based diet; T3, Sorghum based diet with Ronozyme® ProAct and Enviva^® Pro 202 GT; T4, Sorghum based diet with Roxazyme^® G2G and Enviva^® Pro 202 GT; T5, Sorghum based diet with Axtra XAP^® 101 TPT and Enviva^® Pro 202 GT, and T6, Sorghum based diet with Enviva^® Pro 202 GT. Diets were formulated to meet standard requirements. Results showed significant (P < 0.05) difference in the growth performance of birds in starter and finisher phase. Results for digestibility and carcass values in some parameters showed significant (P < 0.05) difference across the different treatment diet, with birds fed sorghum based diet alone having the least values. The net profit (‎₦/bird) for birds fed sorghum based diet without feed additive was low compared with birds fed sorghum based diet with enzyme and probiotics in combination. It was concluded that the synergetic effect of exogenous enzymes and probiotics in sorghum based diets showed complementary effect on performance and increased net profit of broiler production.
