China is the largest forage consumption country in the world. Every year�� more than 2 billion herbivorous livestock need more than 350 million tons of forage but the supply each year is only 250 million tons at present. There is a huge gap in forage supply and great contradiction between grass and livestock. The domestic forage is low-quality and has safety problems�� resulting in poor animal production performance. The degree of localization of forage processing machinery and equipment is low and more than 80% protein feed relies on import; the market share of cultivated forage species is not high and independent innovation and transformation capabilities of scientific research achievements need to be further improved. Due to these factors�� the forage industry in China cannot be developed in a healthy way for a long time. The No.1 Documents released by the Central Government in 2015-2017 emphasized \"speeding up the development of grassland and animal husbandry and strengthening coordinated development of the ternary planting structure of grain�� cash crops and forage materials\" \"optimizing livestock and poultry breeding structure and developing herbivorous animal husbandry\" �� and \"vigorously fostering the modern forage industry system\" ; in 2018�� it also proposed to \"implement the rural revitalization strategy\" so as to improve the quality of agricultural supply. In addition�� for the purpose of accelerating agricultural supply-side structural reform�� the Ministry of Agriculture and Rural Affairs has carried out the conversion of grain to feed in the border area of Inner Mongolia Autonomous Region and the main maize production area beside the Yellow Sea and Huaihai Sea. At the same time�� whole plant silage maize has been promoted and a new agricultural relationship has been developed with the combination of planting and breeding and a balance between grain and grass�� which effectively strengthened the development of herbivorous animal husbandry and increased the income of farmers and herdsmen.
