摘要
高粱是世界上最重要的作物之一,但相对于青贮玉米,饲草高粱的籽实含量明显较低,可消化能量物质不高。此外,青贮高粱的利用方式尚不明确,奶牛日粮中青贮高粱替代玉米青贮的适宜比例以及青贮高粱在高产奶牛饲养中的利用价值等都需要给予研究。
Sorghum is one of the world’s important crops,there is a cost since corn silage,because of its high grain content,which is typically superior in digestible energy content to Sorghum forages.There is also a lack of information on the feeding value of Sorghum silages in high producing dairy cows as well as strategies that may be used for sorghum silage to replace a portion of the corn silage in dairy cattle diets.
