Abstract: This study aimed to investigate the effects of glucose oxidase on the production performance and nutrient metabolism in fast Yellow-feathered broilers.Selected six hundred,0-day-old chickens were randomly allocated to 4 groups, and respectively were fed basal diets with the addition of 0,250,350 and 380 g/t glucose oxidase preparations. Each group had 5 replicates,with 30 chickens per replicate. Parameters in this study included the production performance on days 35 and 70,and the nutrient metabolism on day 45.The results showed that adding glucose oxidase had no effect on the production performance on day 35,while had significant effects on daily gain and feed gain ratio on 36 days to 70 days(P<0.05). Meanwhile,the D group had more significant effects than the B,C groups on daily gain and feed gain ratio(P<0.05). The addition of glucose oxidase in the basal diets had significant effects on the digestion and metabolism of dry matter,organics,crude protein and crude fat on day 45(P<0.05).In conclusion,the addition of glucose oxidase had significant effects on daily gain,feed gain ratio and nutrient metabolic rate in Yellow-feathered broilers with the range of 36 to 70-day-old, and in this experiment conditions, the suitable supplementation was 380 g/t glucose oxidase.
