Feed capable of reducing ratio of soybean crude protein daily ration

The invention provides a feed capable of reducing the ratio of soybean crude protein daily ration. The feed capable of reducing the ratio of the soybean crude protein daily ration comprises modified rapeseed meal, and the modified rapeseed meal is prepared by carrying out enzymatic reaction on fermented rapeseed meal through three proteases. According to the invention, through a new technology of nutrition regulation and daily ration preparation, the modified rapeseed meal is used in the feed formula to effectively replace soybean meal, so that the use amount of the soybean meal is effectively reduced under the condition that the animal production performance is not reduced; the percentage of crude protein provided by soybeans and soybean meal in the daily ration to the total crude protein of the daily ration is reduced, and the percentage of crude protein provided by soybeans and soybean meal in the daily ration of growing pigs and broiler chickens to the total crude protein of the daily ration is 40% or bel
