Research Progress on Reducing and Replacing Nutritional Regulation with Corn and Soybean Meal in Pigs Feed
The proportion of energy feed raw materials and protein feed raw materials in typical pig and chicken feed formulations was about 70％and 25％,respectively,mainly derived from grain crops.The feed formula of China's animal husbandry industry mainly con-sists of corn and soybean meal,with a huge annual consumption of corn and soybean meal.However,the domestic corn had been in a tight balance for a long time,and the situation of high dependence on imports for soybeans was difficult to alleviate.With the deteriora-tion of the international environment,the price of protein raw materials had significantly increased,leading to an increase in feed pro-duction costs.In order to promote the development of animal husbandry,ensure the supply and quality safety of feed in China,the Min-istry of Agriculture and Rural Affairs had formulated the"Reduction and Replacement Plan for Corn and Soybean Meal in Feed".Through measures such as"efficiency improvement,open source,and structural adjustment",local feed raw material resources were fully ex-plored and utilized,and corn and soybean meal reduction and replacement technologies were promoted to reduce the import depen-dence of corn and soybean meal.This article mainly reviewed the nutritional characteristics of corn and soybean meal as alternative raw materials and their application in pig feed,provided a theoretical basis for reducing and replacing nutritional regulation of corn and soy-bean meal in pig breeding.
