Piglet protein feed and production method thereof

The invention relates to a piglet protein feed and a production method thereof, which belong to the technical field of herding feed processing technology. In a method for removing anti-nutritional factors of soybean or soybean residue, hot-press puffing is adopted firstly, and then aerobic fermentation and anaerobic fermentation are carried out. The method can remove the anti-nutritional factors in low-temperature desolventized soybean residue and raw soybean, overcomes the serious defect that the anti-nutritional factors are used as the main protein nutrition sources for the piglets, and promotes the production of a large number of easily digestible functional nutrients and flavor components. The soybean residue material fermented grains and soybean meal material fermented grains of the obtained anti-nutritional factors are the piglet protein feed with good quality, and are used for preparing full-price daily ration for piglets with the ages of 7-70 days, the adding proportion is 15-30%, the feed replacing t
