The invention discloses a kind of crab getting fat feeds and preparation method thereof.It includes: 200-300 parts of maize flour, 60-80 parts of Hemiculter clupeoides, 40-50 parts of pig offal, 20-30 parts of shrimp shell meal, 20-30 parts of wheat stalk powder, 15-20 parts of rice bran, crack rice 25-30 parts, 8-10 parts of the dregs of fat, algae 10-15 parts black, 5-10 parts of Mai Huangcao, 5-7 parts of hawthorn powder, 0.3-0.5 parts of salt, appropriate amount of water by weight；Preparation method includes cleaning up, and is air-dried, crushing, spontaneous fermentation, mixing, extrusion make stick；The present invention can guarantee that its trophic structure is reasonable while reducing feed cost again, is conducive to crab and grows up healthy and sound, and palatability is strong；It is fast in when marquis's molding of extrusion sufficiently by stench fish mud and internal organ grease even into maize flour and mixture of cracking rice, air-dry indeformable, by test of many times and observation, crab is more suitable for import to rod type feed is made, and eating speed is accelerated.

Description

Crab getting fat feed and preparation method thereof

Technical field

The present invention relates to freshwater product cultural technique field, in particular to a kind of crab getting fat feed and preparation method thereof.

Background technique

River crab is full of nutrition, containing multivitamin, is loved by consumers, in order to meet a more and more person sponging on an aristocrats' Demand mostly uses greatly ecological cultivation method cultivating river crab at present, and especially southern breeding scale, during 6-8 month, crab is eaten Amount increases, and food consumption is also with increasing；Expensive with the feed price of fishes and shrimps spiral shell meat configuration currently on the market, aquaculture cost increases Add, be unfavorable for the increasing both production and income of raiser, in addition, the feed palatability of fishes and shrimps spiral shell meat configuration is not strong, influences the speed of getting fat.

Summary of the invention

It is an object of that present invention to provide a kind of 6-8 month crab feed, feed nutrition is structurally reasonable, palatability is strong, benefit In the crab getting fat feed and preparation method thereof that crab grows up healthy and sound and manufacturing cost is low.

What the purpose of the present invention was achieved through the following technical solutions: the crab getting fat feed crab getting fat feed is by weight Part includes: 200-300 parts of maize flour, 60-80 parts of Hemiculter clupeoides, 40-50 parts of pig offal, 20-30 parts of shrimp shell meal, wheat stalk powder 20-30 parts, 15-20 parts of rice bran, crack rice 25-30 parts, 8-10 parts of the dregs of fat, algae 10-15 parts black, 5-10 parts of Mai Huangcao, hawthorn powder 5-7 Part, 0.3-0.5 parts of salt, appropriate amount of water.

The crab getting fat feed preferably one includes: 250 parts of maize flour, 70 parts of Hemiculter clupeoides, pig offal by weight 40 parts, 28 parts of shrimp shell meal, 28 parts of wheat stalk powder, 18 parts of rice bran, crack rice 28 parts, 10 parts of the dregs of fat, 13 parts of black algae, 8 parts of Mai Huangcao, 6 parts of hawthorn powder, 0.4 part of salt, appropriate amount of water.

The crab getting fat feed preferably two includes: 280 parts of maize flour, 80 parts of Hemiculter clupeoides, pig offal by weight 48 parts, 25 parts of shrimp shell meal, 22 parts of wheat stalk powder, 16 parts of rice bran, crack rice 25 parts, 8 parts of the dregs of fat, 12 parts of black algae, 8 parts of Mai Huangcao, 7 parts of hawthorn powder, 0.4 part of salt, appropriate amount of water.

The preparation method of the crab getting fat feed includes the following steps:

Hemiculter clupeoides are removed internal organ, cleaned up by step 1, are air-dried surface layer moisture content, are then comminuted into fish mud, fish mud is placed on Temperature is spontaneous fermentation in the greenhouse of 28-30 degree, and standing time is 6-8 hours, and the control flesh of fish keeps pureed, no infiltration；It is formed Stench fish mud；

Step 2, pig offal are internal organ part (intestines, liver, lung), salt water immersion 0.3-0.6 hours are put into after cleaning up, then It boils 0.1-0.3 hours and takes out in being put into boiled water, it is cooling, it is useless to be broken into internal organ mud；

Step 3, cracks rice and rice bran, wheat stalk powder mix, according to 1:(1-1.3) mix and cooks with water, it is cooling after addition it is oily Slag, black algae, Mai Huangcao, hawthorn powder are ground into mud after stirring evenly, form mixture of cracking rice；

Step 4 forms getting fat feed after stirring maize flour, stench fish mud, internal organ mud, mixture of cracking rice and mixes Object, then closed preservation 24-36 hours, temperature is 23-25 degree；Make the grease of its internal organ and stench fish mud be sufficiently mixed crack rice it is mixed It closes in object and maize flour；

Step 5 takes out getting fat forage mixture, and extrusion makes stick, and a length of 1-2 centimetres of stick, diameter is 0.2-0.4 centimetres, then Natural air drying, pack, forms crab getting fat feed of the invention.

Getting fat forage mixture in the preparation method of the crab getting fat feed is in closed preservation 24-36 hours, often Interval will be stirred primary for 6-8 hours.

The invention has the advantages that: it can guarantee that its trophic structure is reasonable again while reducing feed cost, it is strong conducive to crab Kang Chengchang, and palatability is strong；Fermenting when smelling as of rotten fish fish mud, temperature and time is very crucial, it cannot be made to be fermented into water, protects It holds and smells as of rotten fish and at pureed；Pig offal (intestines, liver, lung) is impregnated by salt water, boiling, and crushing process is rapid at mud without drawing；Getting fat Forage mixture is during closed preservation, timing agitation, sufficiently by stench fish mud and internal organ grease even into maize flour It is fast in when marquis's molding of extrusion in mixture of cracking rice, air-dry indeformable, by test of many times and observation, crab is to being made stick Type feed is more suitable for import, and eating speed is accelerated.
