| 摘 要： | 为研究外源纤维酶对奶牛瘤胃纤维降解细菌的影响,试验选用安装有永久性瘤胃瘘管,年龄、体重相近的3头奶牛为试验动物,采用前后期自身对照试验方法,进行2期动物试验,第1期基础日粮中不加外源纤维酶(对照组),第2期(试验组)基础日粮中,将外源纤维酶组合按日粮的0.1%进行添加饲喂。结果显示,外源纤维酶显著提高了奶牛瘤胃中的白色瘤胃球菌、黄化瘤胃球菌、产琥珀酸丝状杆菌、溶纤维丁酸弧菌、反刍兽真细菌和栖瘤胃普雷沃氏菌(P<0.05～P<0.01)的数量。 |

| Abstract: | In order to study the effects of exogenous cellulase on the bacterial degradation by rumen fiber of dairy cow,three dairy cows with close ages and weight were selected as experimental animals to install permanent rumen fistula.The self-control test method that was consisted of two experimental periods was conducted.During the first period,no exogenous cellulase was supplemented to the basal diet (control group).During the second period,exogenous cellulase combination was supplemented to the basal diet at th... |
