Abstract

The invention discloses a method for preparing feed proteins by utilizing alcohol waste liquor and crop straws, aiming at the current situations that the feed availability of the crop straws is low and the alcohol waste liquor causes severe pollution. The requirements on straw integrated utilization and stock farming feed proteins and the objective needs on innocent treatment and utilization of the alcohol waste liquor are met. The feed protein product which is high in cellulose and xylan degradation degree and high in high-quality protein content is prepared by adopting a process for performing ammoniation, composite enzymatic hydrolysis and multi-strain three-step solid state fermentation, and the product is enriched in probiotics, vitamins, enzymes, amino acids, oligopeptides, high-quality proteins and other nutritional ingredients and has the advantages of promoting growth and development, improving the feed utilization rate, enhancing the immunity, improving the intestinal microecology and preventing diseases. Moreover, feed recycling high-value utilization of the crop straws and the innocent treatment and recycling of the alcohol waste liquor are realized, and the method has wide application prospects.

Description

technical field [0001] The invention relates to a method for preparing feed protein by using alcohol waste liquid and crop stalks, belonging to the field of feed processing. Background technique [0002] Protein raw materials are the foundation of the development of feed industry. The shortage and high price of protein raw materials in my country have become one of the bottlenecks restricting the development of animal husbandry. At present, with the improvement of people's living standards and the emphasis on the quality of life, the demand for meat, eggs, milk, and aquatic products is increasing day by day. The production of grain and feed is facing severe challenges, and feed protein resources will become increasingly scarce. It is imminent to expand feed resources and develop unconventional feed. The important strategy to alleviate the contradiction is to improve the utilization rate of the existing protein source, tap the available nutritional components of the feed as ...
