摘要
选用30日龄杜×长·大三元杂交商品仔猪40头,研究了硫酸粘杆菌素、活菌制剂及酶制剂在基础日粮中单独使用与配合使用对促进仔猪生长及防治腹泻的效果。结果表明,各试验组仔猪平均日增重比对照组有显著提高。其中以在基础日粮中添加硫酸粘杆菌素20mg/kg与添加活菌制剂200mg/kg配合使用效果最明显,比对照组提高了16.7%(P<0.05)。在饲料转化率方面,添加硫酸粘杆菌素20mg/kg不明显,添加硫酸粘杆菌素20mg/kg+活菌制剂200mg/kg和硫酸粘杆菌素20mg/kg+酶制剂1g/kg两组均比对照组有显著提高(P<0.05),从防治腹泻情况看,对照组仔猪腹泻率28%,添加硫酸粘杆菌素20mg/kg腹泻率8.5%,添加硫酸粘杆菌素20mg/kg+活菌制剂200mg/kg和添加硫酸粘杆菌素20mg/kg+酶制剂1g/kg两组未见腹泻。利用硫酸粘杆菌素,特别是将其分别与活菌制剂和酶制剂配合使用,对提高仔猪日增重和饲料转化率以及防止仔猪腹泻发生都有较好效果。
Effect of colistin sulfate,ecologics and enzyme preparations(added in basic diet)on growth and diarrhea prevention in40weanling pigs(Duroc×Landrace·Yorkshire)at30day age were observed.The result showed that:Daily gain of weanling pigs in experiment groups is higher than control group.Especially in group supplemented with20mg /kg colistin sulfate+200mg /kg ecologics got a16.7%significantly higher than control group(P<0.05).Feed conversion ratio in the2groups with20mg /kg colistin sulfate+200mg /kg ecologics and with20mg /kg colistin sulfate +enzyme preparations1g /kg was higher than control group(P <0.05).Diarrhea ratio in control group was28%and8.5%in group with20mg /kg colistin sulfate.Diarrhea was not found in group with20mg /kg colistin sulfate and+200mg /kg ecologics and with20mg/kg colistin sulfate+1g /kg enzyme preparations.It was concluded that adding colistin sulfate could improve daily gain,feed conversion ratio and prevent diarrhea in weanling pigs,especially accompanied with ecologics or enzyme preparations.
