摘要:

本试验旨在研究丁酸梭菌和乳酸菌对青年鸽免疫性能、血清抗氧化指标、小肠消化酶活性和肠道形态的影响。选取80日龄左右的雌性青年鸽384只,将其随机分成4组,每组6个重复,每个重复16只。其中A组饲喂基础日粮,B、C和D组分别在基础日粮中添加1×108 CFU/kg丁酸梭菌、5×109 CFU/kg乳酸菌和5×109 CFU/kg乳酸菌+1×108 CFU/kg丁酸梭菌。预试期7 d,试验期28 d。结果表明:①与A组相比,B、C、D组脾脏指数和法氏囊指数均有所提高,但差异不显著(P>0.05)。②与A组相比,B、C、D组青年鸽血清超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、过氧化氢酶(CAT)活性及总抗氧能力(T-AOC)均显著提高(P<0.05),丙二醛(MDA)含量显著降低(P<0.05);与B、C组相比,D组血清T-AOC及CAT、GSH-Px活性均显著提高(P<0.05)。③与A组相比,B、D组十二指肠内胰蛋白酶活性显著提高(P<0.05),D组脂肪酶活性显著提高(P<0.05)。④与A组相比,D组十二指肠隐窝深度显著降低(P<0.05),B组十二指肠及D组十二指肠、回肠绒毛高度/隐窝深度比值均显著提高(P<0.05)。综上所述,在日粮中添加丁酸梭菌和乳酸菌有利于改善青年鸽肠道形态,提高小肠消化酶活性及血清抗氧化能力,从而增强青年鸽的免疫力。

Abstract:

The study was designed to investigate the effects of Clostridium butyrate and Lactobacillus on immune performance,serum antioxidant indexes and intestinal function in young pigeons.384 female young pigeons about 80 days old were randomly divided into 4 groups with 6 replicates per group and 16 young pigeons per replicate.Among them,group A was fed with basal diet,and groups B,C and D were added 1×108 CFU/kg Clostridium butyrate,5×109 CFU/kg Lactobacillus,5×109 CFU/kg Lactobacillus+1×108 CFU/kg Clostridium butyrate in the basal diet,respectively.The preliminary trial period was 7 d and the trial period was 28 d.The results showed that:①Compared with group A,the spleen index and bursa of Fabricius index in groups B,C,D were increased but the difference was not significant (P>0.05).②Compared with group A,the serum CAT,SOD,T-AOC and GSH-Px of young pigeons in groups B,C,D were significantly increased (P<0.05),the content of MDA were significantly decreased (P<0.05);Compared with groups B,C,the serum CAT,T-AOC and GSH-Px of group D were significantly increased (P<0.05).③Compared with group A,the activity of trypsin in duodenum of groups B and D were significantly increased (P<0.05),and the activity of lipase of group D was significantly increased (P<0.05).④Compared with group A,the duodenal crypt depth in group D was significantly decreased (P<0.05),The ratio of villus height to crypt depth of duodenum in groups B and D,and that of ileum in group D were significantly increased (P<0.05).In conclusion,adding Clostridium butyrate and Lactobacillus to diets could improve the intestinal morphology,increase the activity of intestinal digestive enzymes and enhance the serum antioxidation ability of young pigeons,thereby enhance the immunity of young pigeons.
