| 摘 要： | 在饲喂大麦基础日粮条件下， 适量添喂粗酶制剂可使： ①雄雏鸡（７ ～２１ 日龄） 、肉用仔鸡（１ ～４２ 日龄） 、生长鹅（７ ～６０ 日龄） 及肉鸭（１ ～４２ 日龄） 均在不同程度上提高增重和饲料利用率。②食糜的粘度降低， 通过消化道的速度加快， 改善了消化机能。③血液ＩＧＦ Ⅰ、Ｔ３ 水平明显升高， 促进生长。④提高禽体细胞免疫力。

| Abstract: | A series of experiments in domestic birds fed barley based diet supplemented with crude enzyme were performed.The results showed that① growth rate and feed efficiency in chicks(7～21 days old),meat broiler chickens(1～42 days old),growing geese(7～60 days old)and meat ducks(1～42 days old)were increased to varying extent after the supplement;②viscosity of intestinal content was lowered and the passage rate was faster,which improved the digestive function;③blood levels of IGF Ⅰ,T 3 were elevated;and ④cellular immunity in chicks was enhanced. |
