摘  要：
饲用型甜高粱(青贮)具有抗旱、耐盐碱、耐瘠薄等特性,其生物产量高,水分利用效率好;将其加工成青贮饲料后品质与玉米青贮相当(或更优),可以搭配玉米青贮等其他草料饲喂奶牛,提高适口性,增加奶牛产奶量.培育甜高粱不仅可以解决饲草不足的问题,还能合理利用贫瘠土地资源,为农民带来经济效益.本文对饲用型甜高梁的生物学特性、饲喂价值进行了详细阐述,以期为甜高粱在我国不同地区的推广种植提供一定的依据和参考.

摘  要：
This topic deals with "silage": the effects of milk yield and quality of cows after feeding corn silage,sweet sorghum silage or mixed grain, combined with the rapidly development of dairy cow breeding industry in China,the application of silage feeding in dairy farming and the high cost of raising dairy cows, and so forth.It is concluded that:(1) Forage type sweet sorghum(silage) has high yield,WUE(water use efficiency),and has the characteristics of drought resistance, waterlogging resistance, salt-alkali resistance and barren resistance;(2)The quality of sweet sorghum silage feed, is equivalent to or better than corn(silage), and it can be used with other grasses such as corn silage to feed cows, improved the palatability and increased milk yield of Holstein cows.Cultivation of sweet sorghum can not only solve the problem of insufficient forage grass, but also rationally utilize barren land resources and bring economic benefits to farmers. Therefore, it is hoped for further silage feeding that provides the certain basis and reference for the promotion and planting of sweet sorghum in different regions of China.
