Abstract

The invention discloses a method for preparing fattening feed for river crab in Taihu Lake, the feed comprises the following components by weight percentage: 3-5% of peanut meal, 15-20% of domestic fish meal, 35-40% of soybean meal, 18-20% of wheat, 4-5% of rice bran, 10-15% of rapeseed meal, 2% of soya-bean oil and 4% of premix. The method comprises the following steps: 1)performing superfine grinding on peanut meal, domestic fish meal, soybean meal, wheat, rice bran and rapeseed meal, sending to a mixing warehouse of a mixer in order; 2)directly adding soya-bean oil and the premix in the mixing warehouse of the mixer; 3)turning on a mixer for stirring for 8-10 minutes to prepare a mixture, sending the mixture into a pelleting bin; 4)preparing the slaking particles by the mixture in the pelleting bin through a granulator under high temperature steam effect, sending the slaking particles to a stabilizer and cooling to normal temperature in a stable mode; and 5)grading for processing the cooled particles by a grading sieve, then sealing and packaging according to required weight. According to the invention, the preparation cost is low, the feed nutrition is comprehensive and safe, anaphase growth of the crab is fast, and crab cream can be greatly grown.

Description

Technical field: [0001] The invention relates to the field of aquatic animal feed, in particular to a preparation method of Taihu hairy crab fattening feed. Background technique: [0002] In the Taihu Lake Basin, Taihu hairy crabs are generally fed more corn, small fish and shrimps in the early and middle stages of growth, mainly to ensure product quality and reduce costs. Meat, etc., will affect the yield and quality. If in the later stage of growth, especially from June to August, special fattening feed is used for feeding and fattening, the Taihu hairy crabs will be very plump after being listed in October to November. The yield is high and the quality is good. It is the breeding method that farmers should adopt at present. model. Invention content: [0003] The problem to be solved by the present invention is to provide a preparation method of fattening feed for hairy crabs in Taihu Lake, which has low preparation cost, comprehensive and safe feed nutrition, fast gro...
