There is still no absolutely feed grain circulating system , but the reform of grain circulating system accelerated the development of feed industry . china should promote the integration of feed market 目前中国尚未形成独立的饲料粮流通体系，但近年来粮食流通体制的改革对饲料工业的发展起到了促进作用，中国应加快饲料业市场的整合。
The shortage of protein feed is the mostly problem to hold up the development of feed industry in china . the supply of feed grain is imbalance among different regions , and then the transport cost from north area to south area is very high 另外，饲料粮的供应存在区域间的不平衡，作为主要的饲料加工地和养殖业地区的南方省份，饲料供应不足，而北方饲料粮主产区供过于求，饲料粮的南北调运成本高。
Different animal raising system has different feed grain conversion ratio , and the usage of feed grain in different raising system is also different . the development and change of animal raising pattern will influence the feed grain demand 不同的的畜牧业生产方式下饲料转化率不同，对饲料粮的使用情况也不同，农户散养方式下使用的饲料粮较少，对饲料粮市场依赖不大，而集约经营方式受饲料粮市场的影响较大，专业户养殖介于二者。
