微生态制剂对肉羊生长性能和血液生化指标的影响

Effects of Microbial Ecological Agent on Growth Performance and Blood Biochemical Indices of Meat Sheep

为探讨微生态制剂对肉羊生产性能和血液生化指标的影响,本研究将90只肉羊随机分成3组(对照组、微生态制剂I组、微生态制剂II组),对照组饲喂基础日粮,微生态制剂I组、II组分别在基础日粮中添加500 mg/kg和1000 mg/kg微生态制剂。试验结果显示,微生态制剂I组、II组与对照组相比,将平均日增重分别提高5.61%(P<0.05)和6.99%(P<0.05),料重比分别降低2.68%(P<0.05)和3.13%(P<0.05);将血液中葡萄糖含量分别提高5.30%(P<0.05)和5.08%(P<0.05),总蛋白含量分别提高3.48%(P<0.05)和4.98%(P<0.05),白蛋白含量分别提高3.78%(P<0.05)和4.30%(P<0.05),尿素氮含量分别降低5.12%(P<0.05)和5.65%(P<0.05)。试验结果表明,肉羊基础饲粮中添加500 mg/kg和1000 mg/kg微生态制剂均能显著提高肉羊的生长性能和增强蛋白质合成吸收作用。

The research aimed to study the effects of microbial ecological agent on growth performance and blood biochemical indices of meat sheep. 90 meat sheep were divided into three groups （control group, microbial ecological agent group Ⅰ, Ⅱ）. The control group was fed with basal diet, microbial ecological agent group Ⅰ,Ⅱ were fed with diets added 500 mg/kg and 1000 mg/kg microbial ecological agents. Compared to control, average daily weight gain of microbial ecological agent group Ⅰ, Ⅱ increased by 5.61% （P 〈0.05） and 6.99 % （P 〈0.05）, which feed conversion ratio decreased by 2.68 % （P 〈0.05） and 3.13 % （P 〈0.05）, glucose increased by 5.30 % （P 〈0.05） and 5.08 % （P 〈0.05）, total proteins increased by 3.48 % （P 〈0.05） and 4.98 % （P 〈0.05）, albumin increased by 3.78 % （P 〈0.05） and 4.30 % （P 〈0.05）, urea nitrogen decreased by 5.12 % （P 〈0.05） and 5.65 % （P 〈0.05）. The test results showed the addition of 500 mg/kg and 1000 mg/kg microbial ecological agents could significantly improved the growth performance and enhanced absorption function of protein synthesis.
