Embodiment 1

[0017] A process for preparing liquid protein feed using alcohol fermentation waste mash, the specific preparation steps are as follows:

[0018] (1) Activation of Aspergillus: Take fresh bran, use a 60-mesh sieve to remove fine powder, add water according to the ratio of bran: water = 1: 1.0-1.3, and mix well until there is no dry powder and no agglomeration. After mixing well, divide into 2000mL conical flasks, each 2000mL conical flask contains about 100g of wet bran, sterilize at 0.1MPa gauge pressure for 40-60min, cool to 35°C, put 1-2 Ring the activated spores of Aspergillus oryzae cv-8 and Aspergillus niger sp-1, and control the medium temperature at (35±1)℃. Shake the flask once every 12-24h, and stop preparing the spore suspension after the spores grow out;

[0019] (2) Activation of Candida utilis: Connect Candida utilis to YPD medium, shake the flask at 30°C and 180r / min for 24 hours; then transfer the seed solution to YPD at a ratio of 1:100 In the culture medium...

Abstract

The invention aims at the situations of low feeding utilization of crop straws and serious pollution of waste alcoholic liquid and provides a process for preparing a liquid protein feed by utilizing waste alcoholic fermentation liquor to meet feed protein requirements of the animal husbandry and objective requirements on innocent treatment and utilization of the waste alcoholic liquid. According to the process, an efficient liquid protein feed is directly prepared by utilizing the waste alcoholic fermentation liquor through microbial fermentation and is used for pig breeding, the protein feed contains a great number of nutritional ingredients such as probiotic living bacteria, multiple vitamins, enzymes, amino acid, oligopeptide and high-quality protein, and amino acid compositions are complete; the process has the advantages that the growth development is promoted, the utilization rate of the feed is improved, the immunity is boosted, the intestinal microecology is improved, the disease is prevented, and the environment pollution is reduced. Through the trans-utilization, a great amount of sewage brought by alcoholic production is avoided, the environment is protected favorably, water for pig breeding is saved, the secondary efficient utilization of water resources is achieved, and the process is of great significance in saving of precious water resources of China.

Description

technical field [0001] The invention relates to a process for preparing liquid protein feed by using alcohol fermentation waste mash, which belongs 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 f...
