Abstract

Belonging to the technical field of feed processing, the invention discloses a preparation method for fermented soybean meal suitable for piglet feed. The method comprises the steps of: mixing an impurity removed soybean meal raw material with a small amount of corn flour and rice protein powder uniformly by a mixing machine, and then conducting high temperature sterilization to obtain a basic fermentation raw material; activating lactic acid bacteria, yeast and Bacillus respectively and then conducting mixing so as to obtain a mixed strain liquid; adding 40-50% of warm clean water and 10-15% of the mixed strain liquid into the basic fermentation raw material, and stirring the materials evenly; placing the inoculated basic fermentation raw material into a fermentation tank to carry out fermentation for 60h-72h at 35-42DEG C, thus forming fermented soybean meal; and subjecting the fermented soybean meal to low temperature drying treatment, then grinding the fermented soybean meal into powder, and performing packaging, thus obtaining the product. The method provided by the invention has a simple process, reduces most resistant protein in soybean meal, comprehensively retains the nutrition, can significantly improve the feed intake of weaned piglets, lowers the rate of diarrhea, and significantly increases the weight of piglets.

Description

technical field [0001] The invention relates to a method for preparing fermented soybean meal suitable for piglet feed, and belongs to the technical field of feed processing. Background technique [0002] Protein is the core of the nutrition of weaned piglets and plays a decisive role in the growth and development of piglets. Soybean meal is a plant-based protein feed with high nutritional value. The crude protein content is generally 40% to 50%, and it is rich in essential amino acids, multivitamins, phospholipids and mineral elements. The nutritional components are relatively complete and balanced. Widely used in the feed industry. However, soybean meal contains a variety of anti-nutritional factors and antigenic proteins, which can easily cause allergic reactions and cause problems such as intestinal damage, nutritional diarrhea, and decreased immunity in piglets; when used, it will also cause a decrease in protein utilization, waste of raw materials, and damage to the e...
