Cellulose Enzyme, Phytase And Wheat Enzymes On Broiler Performance And Nutrient Utilization

A 6-week experiment was conducted to determine the effects of 400mg/kg cellulase-preparation enzyme (VP: Bate-glucanase, pectinase, Endo- P -glucanase and Herri-cellulase) , 300mg/kg Phytase and 100mg/kg wheat enzyme (WX: fungal xylanase and glucanase) on growth performance of broilers and nutrient utilization based on corn-soybean-rapeseed meal diets. 1008 1-day-old Avian (504 Avian male and 504 Avian female) were distributed randomly into 8 treatments with 6 replicates of 21 birds. The results showed: (1) , VP supplemented in the normal diet decreased significantly ADG (P<0.0 1) at 1-21 day-old but increased significantly ADG (P<0.05) at 3 6-42 day-old. Feed Conversion rate (FCR) supplementation VP decreased significantly (P<0.0l) at 1-21 day-old, but increased significantly at 22-35 day-old (P<0.0l) and 36-42 day-old (P<0.05). Chicks fed VP had no significantly affect on the Ca concentration, but its P concentration in the tibia at 21-day-old was decreased (P<0.05) significantly. (2), In the normal diets, the combination of VP and Phytase had no significantly affect on ADG and FCR of broilers compared with Phytase only. (3) . Phytase supplemented in the normal diet increased ADG (P
