低聚糖对断奶仔猪生长性能及血清生化指标的影响

The Effect of Different Oligosaccharides on Performance and Serum Biochemical Parameters in the Weaned Piglets

为了研究低聚糖对断奶仔猪生长性能和血清生化指标的影响,试验选用(28±2)日龄荣昌断奶仔猪,在基础日粮相同的情况下进行分组试验,每组6个重复,每重复8头猪。各组日粮中除对照组外,分别添加低聚果糖(0.4%)、低聚木糖(0.02%)、低聚果糖+低聚木糖(分别为0.4%和0.02%),试验为期4周。结果表明:与对照组比较,日粮中添加0.4%低聚果糖、0.02%低聚木糖均显著提高了平均日增重(P<0.05),降低了腹泻率(P<0.05),添加低聚果糖还显著提高平均日采食量(P<0.05),添加低聚木糖显著降低了料肉比(P<0.05)。此外,与对照组比较,添加低聚木糖显著降低了总胆固醇和甘油三酯浓度(P<0.05),低聚果糖组高密度脂蛋白含量显著高于对照组(P<0.05),低聚果糖和低聚木糖对谷丙转氨酶和谷草转氨酶含量无显著影响(P>0.05)。通过对添加低聚糖饲养猪只各项指标的测试,低聚糖能显著改善断奶仔猪的生长性能。

28±2 day-old Rongchang weaned piglets were randomly divided into 4 groups（0.4% fructo oligosaccharide（FOS）,0.02% xylo-oligosaccharide（XOS）,0.4% FOS and 0.02% XOS and control） based on the same basic diet to study the effect of FOS and XOS on the growth performance and serum biochemical parameters of weaned piglets.The trial lasted 4 weeks and each group had suitable replications.Results showed that supplemented with 0.4% FOS or 0.02% XOS significantly increased average daily gain（ADG）（P〈0.05） and decreased diarrhea ratio（P〈0.05） as compared with the control,FOS increased average daily feed intake（ADFI） and XOS decreased feed/gain（F/D）.In addition,as compared with the control,XOS decreased serum total cholesterol（TC） and triglyceride（TG） significantly（P〈0.05）,FOS increased high density lipoprotein（HDL）（P〈0.05）,the concentration of glutamic pyruvic transaminase（GPT） and glutamic oxaloacetic transaminase（GOT） had no significant difference among all groups（P〉0.05）.Oligosaccharide can significantly improve performance in the weaned piglets by the test of different indexs on weaned piglet which is raised by feed with oligosaccharide.
