益生菌对保育猪生产性能和发病率影响的效果试验

Effect of probiotics on production performance and the incidence rate in nursery pigs

在保育猪日粮中添加益生菌,研究其对保育猪生产性能和发病率的影响。选择28 d断奶后健康仔猪100头,随机分成2组(对照组和试验组),每组设5个重复,每个重复10头猪,对照组和试验组分别饲喂不添加益生菌和添加了0.1%益生菌的日粮,试验期为42 d。结果表明:在保育猪饲料中添加益生菌显著增加保育猪的末重(P<0.05);添加益生菌后平均日增重比对照组提高20.6%,发病率降低2%。因此得出,添加益生菌后,显著提高保育猪的生产性能,增加经济效益。

This experiment was conducted to study the effect of probiotics on production performance ofand attack rate. in nursery pigs.One-hundred weaned pig of 28 d were randomly assigned to two dietarytreatments with 50 of each treatments. The groups received the same basal diet supplemented with 0, 0.1%probiotics respectively. The feeding trial lasted for 42 days. The results showed that:1Probiotics raisedthe final weight of the pig(P<0.05);2Average daily gain(ADG) of treatment group is 20.6% higher thanthe control group;3The incidence rate of treatment group is lower 2% than the control group. These re-sults indicated that probiotics could raise production performance of the pig and improve economic perfor-mance.
