不同芽孢杆菌复合菌剂饲喂哺乳仔猪效果比较

COMPARISON OF DIFFERENT COMPOUND BACILLUS IN SUCKLING PIGS

将芽孢杆菌复合菌剂Ａ、Ｂ、Ｃ、Ｄ四种类型按０．ｌ％、０．１５％、０．２％三个剂量 添加到哺乳仔猪补饲料中，饲喂４０窝３４２头２０日龄的哺乳仔猪，至６０天断奶结束， 结果是：①芽孢杆菌复合菌剂作为饲料添加剂应用于哺乳仔猪，对哺乳仔猪生 长速度有显著的促进作用。②在ＡＢＣＤ四种芽孢杆菌复合菌剂中，以Ｃ种芽孢杆 菌添加０．１５％的剂量对哺乳仔猪增重效果最好，经饲喂４０天平均个体净增重达１４ 公斤，比对照组提高增重２３．９％（Ｐ＜０．０１）．试验结果证明，仔猪对芽孢菌类属 存在选择性，适宜芽孢菌类具有明显促生长效应。

342 suckling pigs, from 40 litters were used to study the effects of four kinds of Compound Bacillus in three levels (0. 1%, 0. 15% and 0.2% in diets) on performence, trial period of the age from 20 to 60 days. Tie results showed that compound Bacillus used as feed additive could improve the growth of suckling pigs. Among the four compound Bacillus, type C used 0. 15% in diet provided the best effect on weight gain. It was 23.9% higher than that of the contrast (P<0. 01). Bacillus can be further exploited. Fit Bacillus Can Significawtly Promote piglet growth.
