Effects of Glutamine and Clostridium butyricum on Growth Performance,Immune Function, Small Intestinal Morphology and Microfiora in Weanling Piglets
摘要
Abstract
This experiment was conducted to investigate the effects of glutamine (Gln) and Clostridium butyricum (CB) on growth performance, immune function, small intestinal morphology and cecal microflora in weanling piglets. Two hundred and eighty-eight piglets weaned at the age of 21 d were randomly divided into four groups with three replicates in every group and twenty-four piglets in every replicate. The four groups were basal diet group ( CT), basal diet + 1％ glutamine group ( GT), basal diet + 500 mg/kg Clostridium butyricum group ( CBT), and basal diet + 1％ glutamine + 500 mg/kg Clostridium butyricum group ( GCT), respectively. The results were showed as follows: 1) during 14 to 21 d and 0 to 21 d after weaned, the average daily gain (ADG) of GT and GCT was significantly higher than that of CT, the ADG of GCT was significantly higher than that of CBT, and the feed to gain ratio of GCT was significantly lower than that of CT. 2 ) On the 7th day after weaned, the concentration of complement 4 (C4) in GCT and SOD activity in GT, CBT and GCT were significantly higher than those in CT, meanwhile, the T-AOC in CBT and GCT were significantly higher than that in CT. On the 14th day after weaned, the lysozyme activity, the concentration of complement 3 ( C3 ) and T-AOC in GT, CBT and GCT were significantly higher than those in CT; the concentration of C4 and SOD activity in GT and GCT were significantly higher than those in CT, respectively. 3 ) On the 7th day after weaned, the villus height of duodenum in GT, CBT and GCT were significantly increased compared with that in CT ( P ＜ 0.05); the villus height of ileum in CBT was increased significantly compared with that in CT ( P ＜ 0.05 ); the crypt depth of jejunum and ileum in GCT were significantly reduced compared with those in CT (P ＜0.05). On the 14th day after weaned, the villus height of duodenum and ileum in GCT were significantly increased compared with those in CT ( P ＜ 0.05 ), while the crypt depth of duodenum and ileum in GCT were significantly reduced compared with those in CT (P ＜ 0.05 ). 4 ) On the 14th day after weaned, the number of E. coli in GCT was significantly less than that in CT ( P ＜ 0.05 ), while the number of Bifidobacterium and Lactobacillus were significantly larger than those in CT ( P ＜ 0.05 ).
