膨化发酵玉米秸秆在泌乳奶牛上的大群饲喂效果研究
|
摘要
试验旨在研究膨化发酵玉米秸秆替代羊草、燕麦草在泌乳中期奶牛上的大群饲喂效果,以期实现玉米秸秆资源化利用,降低牧场饲养成本。试验结果表明,使用4.2%膨化发酵玉米秸秆替代羊草、5.2%膨化发酵玉米秸秆替代燕麦草饲喂泌乳中期奶牛,对干物质采食量、产奶量及乳脂率无显著影响,但有效降低了千克奶饲料成本,可望产生良好的经济、社会效益。
To evaluate the large group feeding effects of puffed and fermented corn straw partially replacing of wild rye and oat grass on mid-lactating cows,we carried out the experiment to realize the utilization of corn straw and reduce the feeding cost of pasture.The results showed that lactating cows fed 4.2% puffed and fermented corn straw instead of wild rye or 5.2%puffed and fermented corn straw instead of oat grass,both had no significant effect on the dry matter intake,milk yield and fat percentage,but the feed cost per kilogram milk decreased,which could produce good economic and social benefits.
