The effect of serine protease on broiler growth and carcass quality
Original language description
The experiment was performed to compare the influence of commercial serine protease in broiler grower diets with standard crude protein (CP) and lower CP level on growth parameters and carcass quality. One thousand three hundred twenty 1-d-old Ross 308 broiler chicks of both sexes were randomly allocated into 4 dietary treatments each with three replicates (4 x 3 x 110). Diets with two levels of CP (21.1 and 20.4%) with and without protease were used. At the end of the experiment 36 chickens from each treatment were randomly chosen for carcass quality measurement. Results of the experiment showed that supplement of serine protease to the diets did not have (P >0.05) significant effect on growth performance, but in lower CP diets improved both final body weight (1837.8 g vs. 1854.9 g) and feed conversion ratio (1800.7 g kg vs. 1785.2 g kg). The supplement of protease to the diet with lower CP had positive significant effect (P <0.05) on carcass yield (71.9 vs. 73.0 %). Serine protease s
