EM发酵精料饲喂奶牛的试验

Effects of Concentrate Fermented with EM on Dairy Cattle

用 EM(有效微生物群 )发酵精料代替 30 %的精料饲喂奶牛。结果试验组和对照组的平均日产奶量分别为 2 1 .71± 3.52 kg和 2 0 .45± 3.57kg,差异极显著 (P<0 .0 1 ) ;同时 ,试验组比对照组每头每日节约混合精料 1 .45kg。

In order to test the effects of concentrate fermented with effective microbes(EM) on dairy cattle, 26 Holsteins dairy cattle were selected and divided into two groups, one was the control group and the other is the test group. In the diet of test group, 30% of concentrate was replaced with EM concentrate. The results showed that average daily milk production of a cow in the control group and the test group was 20.45±3.57 kg/d and 21.71±3.52kg/d, respectively, and 1.45 kilograms concentrate per cattle a day was saved in test group.
