With improvement of the living standards, the domestic consumption and production of livestock products such as meat, poultry, eggs, and milk keep increasing, and thus the domestic demand for forage is raised. Based on the analysis of changes in the supply and demand of forage materials in China and the changes in the future demand for domestic livestock and poultry products, the future demand of forage materials is forecasted. The research results show that the gap of supply and demand of forage materials in China will continue expanding in the future, and for the safety of domestic forage supply, cultivation of silage corns should be appropriately expanded and the grass industry in agricultural areas should be developed. Additionally, agricultural resources should be fully and rationally utilized, and the cultivation of crops such as soybeans and rapeseeds should be appropriately expanded to improve the effective supply of domestic meals. Meanwhile, China should make full and reasonable use of overseas agricultural resources to ensure the safe supply of domestic forage materials.
