Protein Substitution Strategy for Ensuring National Food Security in China

Abstract

The most prominent contradiction in ensuring food security of China lies in feed grain and the effective supply of protein feed is the key to satisfy people’s demand for consumption of livestock and poultry products. This study focused on the strategic requirements of ensuring food security and achieving sustainable protein supply, and analyzed the utilization status of protein feed resources and summarized the major problems in protein feed supply. Based on the protein feed resources in China and the potential of protein supply in the international market, this article analyzed the potential for substituting soybean meal in our country. It is expected that by 2035 the soybean imports will have reduced 58.8 million tons compared with 2020 by expanding the planting, increasing the income of oil crops, developing new feed resources, utilizing conventional protein feed resources, efficiently, optimizing the planting structure of forage crops, as well as improving the efficiency of livestock and poultry protein conversion. It is suggested that future efforts should be focused on tapping potentials and expanding resources, strengthening scientific and technological support, also carrying out appropriate import by imptementing major projects such as increasing crop and forage production, improving quality 收稿日期:2023-06-12;修回日期:2023-07-13 通讯作者:姚斌,中国农业科学院北京畜牧兽医研究所研究员,中国工程院院士,研究方向为饲料用酶工程;E-mail: yaobin@caas.cn 资助项目:中国工程院咨询项目“双循环背景下国家粮食安全战略研究”(2022-XBZD-12) 本刊网址:www.engineering.org.cn/ch/journal/sscae
