Abstract: 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.
