Abstract

The aim of the present study was to evaluate the effect of a multi-component dietary protease complex on the growth performance and carcass yields of commercial broiler chickens. A total of 630 Indian River broiler DOCs were considered and assigned to five dietary treatments namely: 1) Positive control (PC), a standard diet with no supplemental protease, 2) Negative control (NC), a diet similar to PC but reduced in CP, digestible EAA, and ME based on supplier’s nutrient matrix recommendation, 3) PC+125 ppm protease (PC+125), 4) NC+125 ppm protease (NC+125), and 5) NC+200 ppm protease (NC+200). The birds were fed experimental diets for 28 days. Body weight (BW), body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR), and survival rate were recorded weekly. On day 28, three birds per treatment were sacrificed for carcass yield analysis. FI was similar among the treatment groups except in the 2nd week where broilers fed PC+125, NC+125, and NC+200 diets had significantly higher (P
