复合微生态制剂对断奶仔猪生长及免疫功能的影响

Effects of Compound Probiotics Preparation on Growth and Immune Function of Weaned Piglets

为探讨复合微生态制剂对断奶仔猪生长及免功能的影响,选择体重相近、健康良好的杜×长×大三元断奶仔猪72头,随机分为3组。Ⅰ组饲喂基础日粮,Ⅱ组饲喂添加0.1%的复合微生态制剂试验日粮,Ⅲ组饲喂添加0.1%的抗生素试验日粮。预试期7 d,正式试验期30 d。结果表明:与Ⅰ组相比,Ⅱ组和Ⅲ组日增重分别提高24.46%和19.01%(P<0.05),料重比分别降低13.04%和12.50%(P<0.05),Ⅱ组血清中IgG含量比Ⅰ组和Ⅲ组分别提高34.96%和47.80%(P<0.05)。说明在断奶仔猪的饲粮中添加复合微生态制剂可提高断奶仔猪日增重,改善断奶仔猪免疫机能。

This study was to investigate the effects of compound probiotics on the growth and immune function of weaned piglets. We selected 72 Duroc × Landrace × Yorkshire weaned piglets with similar weight and good health, and randomly divided them into 3 groups. Group Ⅰ was fed with basal diet. Group Ⅱ was fed with 0.1% compound probiotics test diet. Group Ⅲ was fed with 0.1% antibiotic test diet. The pre-test period was 7 days, and the formal test period was 30 days. The results showed that compared with group Ⅰ, the daily gain of group Ⅱ and group Ⅲ increased by 24.46% and 19.01%(P< 0.05), respectively, and the ratio of feed to weight decreased by 13.04% and 12.50%(P< 0.05). The serum IgG content of group Ⅱ was 34.96% and 47.80% higher than that of group Ⅰ and group Ⅲ respectively(P< 0.05). This shows that adding compound microecological preparations to the diet of weaned piglets can increase the daily gain of weaned piglets and improve the immune function of weaned piglets.
