A method for preparing feed protein by using alcohol waste liquid and crop stalks

Abstract

Aiming at the current situation that crop straws are not highly utilized as feed and the pollution of alcohol waste liquid is serious, the present invention discloses a method for preparing feed protein by using alcohol waste liquid and crop straws, so as to meet the comprehensive utilization of straws, animal husbandry feed protein demand, alcohol Objective requirements for harmless treatment and utilization of waste liquid. The invention adopts the process of "ammonification + compound enzymolysis + multi-strain three-step solid-state fermentation" to obtain a feed protein product with high degradation degree of cellulose and xylan and high content of feed protein. The product is rich in probiotics, vitamins, Nutrients such as enzymes, amino acids, short peptides, and high-quality protein have the advantages of promoting growth and development, improving feed utilization, enhancing immunity, improving intestinal microecology, and preventing diseases; the invention realizes high resource utilization of crop straw Value utilization and harmless treatment and resource utilization of alcohol waste liquid have broad 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 ...
