Northeast China is one of the main production areas of food crops, and the crop species is relatively complete, so the northeast is particularly rich in straw resources. Turning straw resources into fodder can not only solve the problem of competition between human beings and livestock for food, but also reduce the pollution of straw combustion to the environment and improve the soil structure and fertility through overfeeding, so as to realize the recycling of resources. However, how to solve the restriction factors of straw raising livestock has always been a bottleneck problem hindering the rapid development of herbivorous livestock and ecological protection in northeast China.In order to provide reference for solving the core technical problems of straw raising and storage, this paper summarizes the restricting factors of straw feeding in northeast China, and puts forward the corresponding suggestions.
