摘 要:应用EM菌剂、“兴牧宝”复合微生物制剂和“赛诺”复合酶三种生物制剂对奶牛产奶性能影响的研究结果表明:4个处理组中,Ⅲ组比Ⅰ组、Ⅳ组平均产奶量提高差异极显著(P>0.01);Ⅲ组比Ⅱ组产奶量提高差异显著(P>0.05);Ⅱ组比Ⅳ组平均产奶量提高差异显著(P>0.05);Ⅱ组与Ⅰ组及Ⅰ组与Ⅳ组的平均产奶没有显著差异(P<0.05)。试验期内,Ⅰ、Ⅱ和Ⅲ组的头均产奶量分别比Ⅳ组提高37.8kg,70.8kg,129.0kg。分别增加经济效益49.32元、94.98元、174.30元。其经济效益显著。Three biological preparations including EM-flom."Xingmubao"complex microorganism and"Sainu"complex enzyme were used to study the effect of them on milking production of cows. The test cows were divided into 4 groups. The results were as follows; The average milking production of cows in Ⅲ group was significantly more than that in Ⅰ , Ⅳ ( P 〉 0.01 ) and Ⅱ groups ( P 〉 0.05 ), as well as Ⅱ group than Ⅳ group ( P 〉 0.05 ), but there was not significant difference in the average milking production between Ⅱ and Ⅰ groups,and Ⅰ and Ⅳ groups( P 〈0.05).In the period of experiment, the average milking production per cow of Ⅰ , Ⅱ and m groups were significantly increased 37.8,70.Sand 129.0kg than that of Ⅳ group in the period of test.The average net income was increased 49.32.94.98 and 174.30 Yuan per cow than that of Ⅳ group . It was significant economic profit.
