寡糖和益生素对生长肥育猪生产性能的影响

摘要

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%o chlortetracycline and % probiotics+0. 1% Iso-malto oligosaccharides. The effect of additive on growth performance and ability of antioxidatian 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(P<0.05). Compared with the 0. 075%o 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(P>0. 05) . Compared with the 0. 075%o chlortetracycline group, there was no significant difference (JP>0. 05) too.
