复合微生态制剂对肉仔鸡血清生化指标和十二指肠组织形态的影响

本试验旨在研究由鼠李糖乳杆菌和啤酒酵母共生培养物制备的复合微生态制剂对肉仔鸡血清生化指标和十二指肠组织形态的影响。试验选用1日龄健康艾维茵肉仔鸡240只，随机分为6个组，每组4个重复，每个重复10只鸡。对照组饲喂基础日粮，抗生素组饲喂含600 mg/kg金霉素的基础日粮，4个试验组饲喂基础日粮，并在饮水中分别添加0.1%、0.5%、1.0%、1.5%复合微生态制剂。试验结果表明，复合微生态制剂能有效提高肉仔鸡血清钙、磷、总蛋白、球蛋白和白蛋白的含量(P＜0.05)，能降低胆固醇的含量和白球比(P＜0.05)，并使十二指肠肠绒毛密度增加，长度显著增长(P＜0.05)。复合微生态制剂对肉仔鸡血清中某些生化指标和十二指肠组织形态有一定的影响。

Effect of the Complex Probiotics on Serum Biochemical Parameters and Morphology of Duodenum for Broilers

In order to study the effect of the symbiotic ferment culture of Lactobacillus rhamnosus and Saccharomyces cerevisiae on serum biochemical parameters and morphology of duodenum of broilers, 240 one-day-old broilers for a experimental period of 42 days,were randomly allotted into six groups, each with four replicates,and each replicate contain ten broilers.The control group was provided with basic diet,the antibiotic group was fed with basic diet supplemented with aureomycin at the level of 600 mg/kg, and the four test groups were fed with basic diet by providing water containing the complex probiotics,at the level of 0.1%,0.5%,1.0%,1.5%,respectively. The results showed that the concentration of Ca,P,total albumen,albumin and alobulin were significantly increased in serum of broilers by the complex probiotics (P＜0.05),the concentration of total cholesterin and the proportion of albumin and globulin were decreased significantly (P＜0.05),and the length of the villus in duodenum of broilers was increased significantly (P＜0.05),the morphological characteristics of mucosal in duodenum was also improved. The results indicated that the complex probiotics had a certain impact on some biochemical in serum and duodenal morphology for broilers.
