寡糖和益生素对生长肥育猪生产性能的影响

Effects of Oligosaccharides and Probiotics on Growth Performance of Fattening Pig

试验选择90头生长育肥猪完全随机设计分成5组,每组3个重复,每个重复6头。试验组在基础日粮中分别添加1%益生素,0.2%异麦芽低聚糖,0.075‰金霉素和1%益生素+0.1%异麦芽低聚糖,观察其对育肥猪生长性能和抗氧化能力的影响。结果表明,添加1%益生素,0.2%异麦芽低聚糖和1%益生素+0.1%异麦芽低聚糖组育肥猪平均日增重均显著高于未添加组(P<0.05),和金霉素组相比,无显著差异。添加1%益生素,0.2%异麦芽低聚糖和1%益生素+0.1%异麦芽低聚糖组血清总SOD均高于未添加组,但差异不显著(P>0.05),和金霉素组相比,也无显著差异(P>0.05)。

In this study,total 90 fattening pigs were randomly divided into 5 groups with 3 replicates（6 pigs per replicate）.The basic diet of these 5 groups was similar.Experiment groups were basal diet added： 1% probiotics,0.2% Iso-malto oligosaccharides,0.075‰ chlortetracycline and 1% probiotics＋0.1% Iso-malto oligosaccharides.The effect of additive on growth performance and ability of antioxidation in fattening pigs were observed.The results showed that the average daily gain of 1% probiotics groups,0.2% Iso-malto oligosaccharides groups and 1% probiotics＋0.1% Iso-malto oligosaccharides groups were obviously higher than control group（P0.05）.Compared with the 0.075‰ chlortetracycline group,there was no significant difference.The SOD contents of 1% probiotics groups,0.2% Iso-malto oligosaccharides groups and 1% probiotics＋0.1% Iso-malto oligosaccharides groups were also higher than control group,but was no significant difference（P0.05）.Compared with the 0.075‰ chlortetracycline group,there was no significant difference（P0.05） too.
