Effects Of Dietary Xylooligosaccharide On Growth Performance, Serum Biochemical Parameters, Antioxidant Function, And Immunological Function Of Nursery Piglets

Abstract

This study investigated the effects of dietary xylo-oligosaccharide(XOS) on growth performance, serum biochemical parameters, antioxidant function,and immunological function of nursery piglets. In total, three groups including 72nursery piglets were designed and fed one of three diets: a control basal diet, basaldiet supplemented with 0.2% ZnO, or basal diet supplemented with 0.04% XOS, for28 days. Compared with the control group, the XOS group significantly increased thefinal body weight and average daily weight gain. No significant differences were foundabout these parameters between the control and ZnO groups. Compared with thecontrol group, the ZnO group showed no changes in the serum content of total protein(TP), albumin (ALB), albumin:globulin (ALB:GLB), aspartate aminotransferase (AST),alanine aminotransferase (ALT), blood urea nitrogen (BUN), glucose, triglyceride,total cholesterol (TC), or in the serum activity of amylase and alkaline phosphatase.However, in the XOS group, serum glucose content increased and blood urea nitrogenand triglyceride content decreased significantly. Compared with the control group,dietary supplementation with XOS significantly increased the serum activity of totalantioxygenic capacity, superoxide dismutase, and catalase and decreased the serumactivity of malondialdehyde. At the same time, serum IgG content in XOS group wassignificantly higher than that in control group. From the current study, supplementationof 0.04% XOS in the diet could improve the antioxidant and immune function of piglets,promotes nitrogen deposition, and accelerates lipid and glucose metabolism, therebyimproving piglet growth performance
