Abstract

The invention belongs to the technical field of biochemistry, and discloses a crayfish feed and a preparation method. Process parameters of the crayfish feed taking fermented cow dung as a main component are determined, and the process parameters are optimized by controlling important variables in the fermentation process so as to guide the actual production. According to the crayfish feed, following two-stage combined fermentation is carried out: step 1, mixed fermentation is carried out in a microbial ex-situ fermentation bed; and step 2, anaerobic fermentation is carried out by selecting lactobacillus casei, lactobacillus plantarum and lactobacillus acidophilus as fermentation strains. Agricultural waste cow dung and other ingredients are fermented to prepare the crayfish fermented feed, so that the problem of cow dung pollution is solved, rich nutrition can be provided for crayfishes, the breeding input cost is reduced, and the economic benefit is very high. Meanwhile, a crayfish fermented feed process taking the fermented cow dung as the main component is systematically researched, and therefore, the fermentation process and the production stability are determined and the product effect is ensured.

Description

technical field [0001] The invention belongs to the technical field of biochemistry, and in particular relates to a crayfish feed and a preparation method thereof. Background technique [0002] At present, crayfish has become an important aquaculture species in my country. In artificial breeding, crayfish feed has become an extremely important part, and scientific and efficient feed formula has gradually become a key factor to increase crayfish production. [0003] Microbial fermented feed is a feed obtained by fermenting feed materials with microbial agents. Nutrients such as small peptides, amino acids and digestive enzymes produced in the fermented feed can promote the growth and development of aquatic animals, improve the utilization rate of feed, save breeding costs, and can enhance the immunity of the body, reduce the occurrence of diseases, and increase the production of aquaculture . Moreover, the probiotics and other microorganisms contained in the microbial ferm...
