摘要
选用体重9 kg左右的杜×长×大三元杂交断奶仔猪60头,根据体重大小性别比例随机分成两组,即对照组和试验组,每组30头,对照组喂基础日粮,试验组喂基础日粮+0.1%猪用复合酶制剂,试验期35 d。结论是在断奶仔猪的基础日粮中添加复合酶制剂,可以使断奶仔猪的平均日增重提高6%,且两者差异显著(P<0.05);饲料报酬比对照组提高了5.6%(P<0.05);每千克增重饲料成本降低0.14元,经济效益提高了4.4%。
60 early weaned and about 9kg piglets were selected which was from three way cross Duroc × Landraec × Large Yorkshire and divided to two groups which was control and experimental group by weight and sex. The number of every group was 30. The control and experimental group was feed with based diet and based diet ＋0. 1% compound enzymes for pig. The experimental time was 35 d. The result showed that compound enzymes in diet make the mean weight increment to increase 6% every day. And the difference between the group was significant （P〈0.05）. Compared with control, feed conversion efficiency of experimental group increased 5.6% （P〈0.05）, and the price of feed decreased 0. 14 yuan, the benefit increased 4.4%.
