摘要: 本试验研究葡糖糖氧化酶对快大黄羽肉鸡生产性能和养分代谢的影响,选择600只0日龄雏鸡分为A、B、C、D 4个处理,每个处理5个重复,每个重复30只,分别在基础日粮中添加0、250、350、380 g/t葡萄糖氧化酶制剂,测定35、70日龄的生产性能和45日龄的养分代谢率。结果表明,35日龄时,黄羽肉鸡的生产性能不受葡萄糖氧化酶制剂添加的影响;葡萄糖氧化酶制剂对36~70日龄黄羽肉鸡的日增重和料重比有显著影响(P<0.05),D组与B、C组在日增重和料重比上有显著影响(P<0.05);添加葡萄糖氧化酶制剂对45日龄黄羽肉鸡的干物质、有机物质、粗蛋白质、粗脂肪的消化代谢有显著影响(P<0.05)。因此,葡萄糖氧化酶对36~70日龄黄羽肉鸡的日增重、料重比和养分代谢率有显著影响,且在本试验条件下,添加380 g/t葡萄糖氧化酶制剂最适宜。

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.

Key words: glucose oxidase; Yellow-feathered broilers; production performance; nutrient metabolism
