Effects of Radix pseudostellariae Stem and Leaf Polysaccharide on Growth Performance, Antioxidant Indexes, Immune Indexes and Biochemical Indexes in Serum of Weaned Piglets
摘要
Abstract
This study was conducted to investigate the effects of dietary Radix pseudostellariae stem and leaf polysaccharide ( RPSLP) on growth performance, antioxidant indexes, immune indexes and biochemical inde⁃xes in serum of weaned piglets. One hundred and twenty 25⁃day⁃old “Large White×Landrace” weaned piglets were selected and randomly allocated into four groups including control group, groups Ⅰ, Ⅱ and Ⅲ, with three replicates per group and ten piglets per replicate. The piglets were fed a basal diet supplemented with 0, 500, 1 000 and 1 500 mg/kg RPSLP, the experiment lasted for 30 days. The results showed as follows:com⁃pared with the control group, 1) average daily gain ( ADG) of weaned piglets in groupsⅠandⅡwas signifi⁃cantly increased (P<0.01), and the diarrhea rate in groups Ⅰ, Ⅱ and Ⅲ was significantly decreased (P<0.01). 2) The activity of superoxide dismutase (SOD) in serum in groups Ⅱ and Ⅲ was significantly in⁃creased ( P<0.01 or P<0.05) . 3) The contents of immunoglobulin A ( IgA) ( P<0.01) , complement 3 ( C3) (P<0.01), complement 4 (C4) (P<0.01) and immunoglobulin M (IgM) (P<0.05) in serum in groupsⅠ, Ⅱ and Ⅲ were significantly increased. The content of immunoglobulin G ( IgG) in serum in groups Ⅱand Ⅲ was significantly increased ( P<0.05) . 4) The content of triglycerides ( TG) in serum in groupsⅠ,Ⅱand Ⅲ was significantly decreased ( P<0.01) , and the content of urea nitrogen ( UN) in serum in groups Ⅱand Ⅲwas significantly decreased ( P<0.01) and the content of albumin ( ALB) in serum was significantly in⁃creased ( P<0.01) . It is concluded that dietary RPSLP can effectively increase ADG, decrease diarrhea rate, and improve immune function, antioxidant performance and biochemical indexes in serum of weaned piglets. The appropriate supplemental amount of RPSLP in diets of weaned piglets is 1 000 mg/kg under this experi⁃mental condition.关键词
