【摘要】 本文探讨了复合酶制剂 81 8A对幼龄蓝狐生长发育的影响。随机选取 50日龄左右蓝狐 80只 ,分成 5组 ,每组 1 6只。Ⅰ组为对照组 ,只饲喂基础日粮 ;Ⅱ、Ⅲ、Ⅳ、Ⅴ组为试验组 ,依次在基础日粮中添加 0 2 %、0 4 %、0 6%、0 8%的复合酶制剂 81 8A ,经 56d试验 ,结果表明 :各试验组狐平均日增重极显著高于对照组 (P <0 0 1 ) ,周体长增长值显著大于对照组 (P <0 0 5) ,同时料重比极显著低于对照组 (P <0 0 1 ) ,换毛时间也较对照组显著缩短 (P <0 0 5)。在各试验组中 ,Ⅲ、Ⅳ组生长较快 (P <0 0 5) ,Ⅳ、Ⅴ组病死率较低 (P <0 0 5)。更多还原

【Abstract】 The results showed that the average increasing weight per day of fox in experimental group was significantly greater than control,and the increasing length per week was significantly bigger than control.In the meantime,the ratio feed and body weight in experimental group was significantly lower than control,and the term of changing fur in experimental group was obviusly shorter than control.In experimental groups,the foxes in Ⅲ,Ⅳ groups grew faster than those in other groups and the foxes in Ⅳ,Ⅴ groups were better than those in other groups.更多还原
