摘　　要：近年来我国畜牧业发展迅速,奶牛存栏数量呈现逐年增加的趋势,与此同时,人们对各类奶制品需求量的逐渐增加,进一步带动了以奶牛业为核心的畜牧业发展。目前一些大型畜牧场将玉米(Zea mays)饲草作为畜禽的主要饲料,远不能解决畜牧业快速发展导致的饲草不足问题。甜高粱(Sorghum bicolor)是一种仅次于青贮玉米的优良饲草作物,耐干旱,耐贫瘠,生物产量高,籽粒可以用作配合饲料,茎叶和秸秆可进行青饲、青贮等。本文从甜高粱的刈割、甜高粱不同预处理方式及甜高粱的多功能用途等方面进行综述,对甜高粱饲喂奶牛的效果进行综合对比,并提出饲用应注意事项等,旨在为今后使用甜高粱饲喂奶牛提供一些技术参考。Animal husbandry in China has developed rapidly in recent years. The number of dairy herds has increased annually due to high demand for all types of dairy products, which further promotes the development of animal husbandry in the dairy industry. Large livestock farms use corn silage to feed livestock, the supply is in sufficient to meet the demand for forage caused by the rapid development of animal husbandry. Sweet sorghum （Sorghum bicolor） is a good forage crops after corn silage; it is a high-yielding, drought-resistant grain that can be used as feed. Additionally, the stems and leaves can be used as forage and silage, among other uses. This manuscript is a preliminary review on sweet sorghum mowing, pretreatment methods and multiple uses. To provide some technical reference for the future of animal husbandry in China using sweet sorghum-fed cows, we analysed the effect of feeding sweet sorghum to dairy cows and put forward matters needing attention.
