A preparation method of shrimp and crab biological feed added with rice distiller's grains

Abstract

The invention relates to a preparation method of a shrimp and crab biological feed added with yellow rice wine lees. The preparation method is characterized by comprising the following preparation steps of: preparing a shrimp and crab biological feed: preparing fermented trash fish meal, fermented shrimp shell meal, fermented soybean meal, fermented peanut meal, fermented cotton meal, fermented rapeseed meal, puffed corn flour, flour, yellow rice wine lees and calcium biphosphate; quenching and tempering the materials, and adding fish oil, Vc condensed phosphate portions and a fish premix compound for mixing; preparing the quenched and tempered mixture into a shrimp and crab biological feed with a molding machine; and molding the shrimp and crab biological feed, preserving heat, cooling at normal temperature and packaging. In the method, yellow rice wine lees are added into the biological feed, so that a nutrition implementing function is realized together with fermented dregs in the biological feed, the production cost is reduced, the food falling property of the biological feed is further enhanced, and the growth promotion and disease resistance of the biological feed are further enhanced; and meanwhile, the production cost of the biological feed can be reduced, and the economic benefit of shrimp and crab cultivation is more remarkable.

Description

Technical field [0001] The present invention involves a method of preparation of shrimp and crab feed, especially the preparation method of shrimp and crab feed that adds cotton grains. Background technique [0002] River crabs, South White Plaid Plays, Roche Nam Shrimp, Kesharachi Shi Shrimp, and Japanese Marsh shrimp have formed industrialized production in China.Soybean meal, peanut meal, cotton meal, cotton meal, vegetable meal, corn flour and wheat flour are the most commonly used feed raw materials. After the above raw materials are crushed, they are used as the main raw materials for shrimp and crab feed to produce granular feed.The protease inhibitory factors will hinder the absorption of protein in the feed, which is not conducive to the improvement of feed efficiency. The mustard glycoside in the cauliflower will produce a variety of toxic substances in the digestive tract under the action of mustard enzymes, which can easily cause shrimp, crab and fish.Poisoning react...

Problems solved by technology

[0002] River crab, Penaeus vannamei, Macrobrachium rosenbergii, Procambarus clarkii and Macrobrachium japonicus have formed industrialized production in China, and the matching feed The industry has also formed a large-scale production. Fish meal, shrimp shell meal, soybean meal, peanut meal, cotton meal, rapeseed meal, corn flour and wheat flour are the most commonly used feed raw materials. The above raw materials are used as shrimp and crab feed after crushing The main raw material of soybean meal is used for the production of pellet feed. The trypsin inhibitor in soybean meal will hinder the absorption of protein in feed, which is not conducive to the improvement of feed efficiency. The myrosinin in rapeseed meal will be produced in the digestive tract under the action of myrosinase A variety of toxic substances can easily cause poisoning reactions in shrimp, crab and fish. Anti-nutritional factors such as erucic acid, phytic acid and tannin in rapeseed meal have a greater impact on the absorption of nutrients in feed. In addition, soybean meal , rapeseed meal and cotton meal have problems such as poor food attraction and low digestion and absorption rate. Therefore, directly using cakes for feed production has a greater impact on the quality and feeding effect of feed, while feed with incomplete digestion and absorption Not only is it a waste, but also pollutes the water quality
