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)(P0.05) and decreased diarrhea ratio(P0.05) 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(P0.05),FOS increased high density lipoprotein(HDL)(P0.05),the concentration of glutamic pyruvic transaminase(GPT) and glutamic oxaloacetic transaminase(GOT) had no significant difference among all groups(P0.05).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.
