| 摘 要： | 选择健康、体重一致的1日龄商品代AA肉鸡960只随机分为4组,每组8个重复,每个重复30只,研究分别在玉米-豆粕型日粮和玉米-小麦-豆粕型日粮中添加粗酶制剂对肉鸡生产性能和食糜黏度的影响。结果表明,添加粗酶制剂显著降低了肉鸡的料重比(P<0.05),有提高肉鸡1~42日龄日增重和出栏体重的趋势(P<0.10);在玉米-小麦-豆粕型日粮中添加粗酶制剂可以显著降低肉鸡食糜的黏度(P<0.05)。结果揭示,添加粗酶制剂可以降低肉鸡肠道内食糜的黏度,改善肉鸡的生产性能。

| Abstract: | An experiment was conducted to study the effect of crude enzyme preparation on growth performance and digesta viscosity in broilers fed corn-soybean diets and corn-wheat-soybean diets.A total of 960 1-day-old broilers were randomly allocated in to four treatments.Each treatment had 8 replicates,with 30 birds per pen.Crude enzyme preparation reduced feed conversion rate(FCR)(P<0.05).Average daily gain(ADG) and body weight(BW) were numerically increased(P<0.10) for broilers fed the diet supplemented with crude enzyme preparation.The digesta viscosity of corn-wheat-soybean diets decreased with the addition of crude enzyme preparation(P<0.05).The results suggested that crude enzyme preparation can improve growth performance in broilers. |
