溶菌酶对断奶仔猪生长性能的影响

Effect of lysozyme on growth performance of the weaned piglet

试验选取28日龄杜×长×大三元杂交断奶仔猪60头,始重差异不显著(P>0.05),随机分成3组,每组20头,分别为对照组(日粮中不添加溶菌酶)、试验Ⅰ组(每吨日粮添加溶菌酶300g)、试验Ⅱ组(每吨日粮添加溶菌酶500g),每组2个重复,每个重复组10头,试验期为4周。试验结果表明:与对照组相比,在断奶仔猪日粮中添加溶菌酶500g/t能够控制腹泻、提高日增重16.68%,差异显著(P<0.05);降低料重比12.00%,差异显著(P<0.05),可以替代抗生素。

The experiment used 60 heads Duroc×Landrace×Yerkshire piglet at the 28 days, the diversity of beginning body heavy was not significance （P〉0.05）, and they were divided into three groups randomly, each group has 20 heads, respectively, the control group does not add lysozyme , the experiment Ⅰ group adds lysozyme 300 g/t, the experiment Ⅱ group adds lysozyme 500 g/t. Each group has two repetitions and each repetitions group 10 heads, the experimental period was 4 weeks. The result indicated, adding lysozyme 500 g/t can control the diarrhea,increase the daily weight gain 16.68% and decrease the ratio of feed/grain 12.00%, the diversity was significane （P〈0.05）. The result indicated the lysozyme may substitute the antibiotic.
