低聚糖对断奶仔猪生长性能及血清生化指标的影响

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。

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

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.
