Abstract: Since the 21st century,the economy of our country has developed rapidly,and the demand for meat products has increased year by year. As a result,the rapid development of livestock farming has been accompanied by the increasing shortage of forage supply,and leads to the high cost of traditional feed. Thus it is important to find an alternative feeding forage. Sweet sorghum,as a high quality forage crop,has high sugar content,large biomass,rich in nutrients,and in additional strong tolerance to stress,can be planted in marginal land. As forage,sweet sorghum can be fed to cattle,sheep,donkeys,fish,rabbits,geese,etc.,and as well as be a portion for pigs. Recently,more and more research on the application of sweet sorghum have been carried out,and the planting area has been expanded year by year in foreign countries and in many places in China,which has a very good prospect of development. It will play an important role in meeting the demand for meat products in our country and promoting the development of livestock farming in the future. This article summarize the advantage and disadvantage of sweet sorghum as forage and point out the future direction about how to breed it for widely usage.
