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

The compound method of a kind of Taihu Lake steamed crab fattening feed

Technical field:

The present invention relates to aquatic animal feed field, particularly the compound method of a kind of Taihu Lake steamed crab fattening feed.

Background technology:

Taihu Lake basin Taihu Lake steamed crab generally growth early stage and mid-term many hello corn, small fish shrimp etc., mainly for ensureing product quality and reducing costs, if the later stage also with this pattern feed just there will be fertile greatly and not, do not get fat without situations such as meat, can seed output and quality be affected.If at later stages, particularly feed with special fattening feedstuff when June to August and fatten, be exactly very fertile Taihu Lake steamed crab in October to November after listing, output high-quality is good again, is the aquaculture model that current raiser should adopt.

Summary of the invention:

Problem to be solved by this invention is just to provide the compound method of a kind of Taihu Lake steamed crab fattening feed, and preparation cost is low, and comprehensively and safety, crab late growing stage is fast, long cream of putting on flesh for feed nutrition.

In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: the compound method of a kind of Taihu Lake steamed crab fattening feed, it is characterized in that: described fattening feed comprises the constituent of following weight percent meter: peanut meal 3-5%, domestic fish meal 15-20%, Soybean Meal 35-40%, wheat 18-20%, clear chaff 4-5%, dish dregs of rice 10-15%, soya-bean oil 2%, premix 4%, described compound method comprises the following steps:

(1) respectively peanut meal, domestic fish meal, Soybean Meal, wheat, clear chaff, the dish dregs of rice are carried out ultramicro grinding, then send into successively in the mixing bunker of mixer;

(2) directly soya-bean oil, premix are added in the mixing bunker of mixer;

(3) start mixer stirring and make compound in 8-10 minute, compound is sent into and treats in granulation storehouse;

(4) compound in granulation storehouse, by making slaking particle during granulator under high-temperature steam effect, is cooled to normal temperature by stable in slaking particle feeding stabilizer;

(5) the classified sieve classification process of cooled particle, then packs by required weight.

Further, the proportioning of described premix is by weight percentage: calcium dihydrogen phosphate 37.5%, stone flour 22%, Choline Chloride 5%, betaine 5%, shelling element 2.5%, aquatic products specific enzyme 2.5%, the many ore deposits 12.5% of fishes and shrimps, fishes and shrimps multidimensional 12.5%, allicin 0.5%.

Advantage of the present invention and effect: the fattening feed comprehensive nutrition of this method preparation, cost is lower, and crab grows fast quality better, and mass rate of production is secure; And the present invention takes full advantage of the abundant agricultural byproducts resource in this area as wheat, clear chaff, the dish dregs of rice etc., meets recycling economy development requirement.
