Biotechnology application of single enzyme and multienzyme in feed, and its effect on growth performance and carcass persentage in broiler

Bromelain as a single enzyme is widely used as a meat tenderizer; but it can damage meat cells. The effect of adding multienzyme Phyprozyme HP in feed is not yet known, so it needs to be researched. This study aims to evaluate the growth performance and carcass persentage of broilers with addition of single enzyme and multienzymes. Each enzymes use 72 Lohman MB 202 Grade Platinum broilers aged 21 to 35 days, 6 treatments and 4 replications with Completely Randomized Design (CRD). Each enzymes use 72 broilers with 6 treatments and 4 replications. P0 as the control feed. Bromelain was added at P1 (600), P2 (1200), P3(1800), P4 (2400), P5 (3000) GDU/kg. Phyprozyme HP was added at P1 (0.19), P2 (0.26), P3 (0.33), P4 (0.40), and P5 (0.47) g/kg. Parameters measured include body weight, body weight gain, and carcass percentage. The results are analyzed using One-Way ANOVA. The addition of bromelain in feed decreases body weight, while the addition of multienzyme significantly improves broiler performance up to a dose of 0.33 g/kg feed. The addition bromelain decreases carcass percentage to 11.07%, while the addition of multienzyme increases carcass percentage to 8.83%, but decreases it to 7.68% at the highest dose.
