抗菌肽对肉牛生长性能及经济效益的影响OA北大核心CSTPCD
Effects of antimicrobial peptides on growth performance and economic benefits of beef cattle
试验旨在研究不同水平的抗菌肽对西门塔尔杂交肉牛生长性能、瘤胃发酵参数、血清免疫力及养殖经济效益的影响.试验选择32头健康、体重相近的西门塔尔杂交肉牛,随机分成4组,每组8个重复,每个重复1头肉牛.对照组饲喂基础饲粮,试验A组、B组、C组分别饲喂含有2、4、8 g/(头·d)抗菌肽的饲粮.预试期7d,正式试验期150 d.结果表明:与对照组比较,试验B组和试验C组的末重和平均日增重显著升高(P＜0.05),料重比显著降低(P＜0.05);瘤胃液的p…查看全部>>
The aim of the experiment was to study the effects of different levels of antimicrobial peptides on the growth performance,rumen fermentation parameters,serum immunity,and breeding economic benefits of Simmental hybrid beef cattle.A total of 32 healthy Simmental crossbred beef cattle with similar body weight were randomly divided into four groups,with eight replicates per group and one beef cattle per replicate.Beef cattle in the control group were fed a bas…查看全部>>
