Comparative study of the effects of several effective microorganisms on growth performance,serum biochemical indexes in growthing pigs

为了研究和比较几种不同微生态制剂对生长猪生产性能和血清生化指标的影响,试验选用60 kg左右的杜×长×大三元杂交生长猪150头,随机分为5组,每组设3个重复,每个重复10头,1组为对照组,饲喂基础日粮,2～5组分别在基础日粮中添加75 mg/kg赐美健、0.2%的枯草芽孢杆菌、0.2%金倍素和0.2%嗜酸乳杆菌,进行为期35 d的饲养试验。结果表明:与对照组相比,2～5组平均日增重分别提高0、2.78%、11.11%、9.72%,其中4(0.2%金倍素)组和5(0.2%嗜酸乳杆菌)组显著高于其他试验组(P<0.05);2～5组均有提高总蛋白、白蛋白含量,降低尿素氮含量和提高碱性磷酸酶活性的趋势,其中4(0.2%金倍素)组的总蛋白含量显著高于对照组(P<0.05)。说明在日粮中添加微生态制剂可以提高生长猪生长性能,改善血清生化指标,且以添加0.2%金倍素的效果最佳。

To compare the effects of several different effective microo/ganisms （EM） on growth performance , serum biochemical indexes in growthing pigs, 150 growing pigs （Duroc x Landrace x Big Shanyuan pig） with an average weight of 60 kg were used and randomly divided into five groups with three replicates in each group, each repeat had 10 pigs. Group I was fed the basal diet as the control group, the other four groups were supplemented with 75 mg/kg Cimeijian, 0.2% of Bacillus subtilis,O. 2% of Jinbeisu and 0.2% of Lactobacillus acidophilus in the diets respectively , the feeding trials lasted 35 d. The results showed that compared with the control group, the average daily gain（ADG） were increased 0, 2.78 %, I 1.11% and 9.72% in the other groups ,repecfively. In which the two groups of 0.2% jinbeisu and 0.2% Lactobacil- lus acidophilus were significantly higher than that of other experimental groups （P 〈 0.05 ）. The four treatment group had the trend to increase the content of total protein and albumin, decreasing the content of urea nitroge and ineresing activity of alkaline phosphatase. The results indi- cate that EM added to the diet can improve the growth performance of growing pigs, improving the serum biochemical indexes, with an optimum effect at the addition of O. 2% of Jinbeisu.
