摘要
苹果发酵饲料是根据现代生物技术和营养理论生产的一种低成本、高效益绿色生物活性饲料。本试验选用38头荷斯坦奶牛,按年龄、胎次、泌乳月、产奶量相近的原则进行分组配对,分为试验组和对照组,试验组用苹果发酵饲料替代10%的精料,试验期为60d。结果表明,在不增加饲养成本的条件下,试验组奶牛平均产奶量要比对照组高0.58kg/d,这说明饲料中添加苹果发酵饲料,能提高产奶量,延长奶牛产奶高峰,相对降低饲料成本,经济效益显著。
Fermented apple byproducts(FAB)is a new production based on modem biotechnology and nutrient theory.The effects of FAB on dairy cows`milk yield was determined by38Holstein dairy cows which were separated to two groups,one was feed base diets,another was feed diets which was substitute10percent by FAB,After60days`feeding experiment,average daily milk yield of FAB group increased0.58kilogram compared to contrast.The result of this study demonstrated that,the FAB can increase milk yield and improve the performance of lactating dairy.
