摘要
为了探究乳酸菌微生态制剂在提高奶牛产奶量方面的作用,本试验选择3个牧场进行试验。每个牧场选取胎次、泌乳天数、产奶量相近的奶牛并分为2组,对照组饲喂基础日粮,试验组在此基础上以奶牛精饲料的5%添加乳酸菌微生态制剂,试验周期30d,每天测定奶牛产奶量。结果表明,添加乳酸菌微生态制剂能够提高奶牛产奶量,并且随着乳酸菌微生态制剂使用时间的延长,奶牛产奶量不断增加,可大大提高奶牛饲养效益。
To study the function and application of probiotics lactic acid bacteria on improvement of milk production, the experiments performed in three pastures, the cows were randomly selected and divided into 2 groups. Probiotics lactic acid bacteria were added in the concentrated feed of the treatment group, and the adding amount is 5%of the concentrate feed. The milk production was measured everyday for 30 days. The results showed that the supplement probiotics lactic acid bacteria could improve the milk production and the dairy cattle breeding, effectively.
