Abstract

The invention discloses a compound feed for healthy aquaculture of grass carps in a large water area and a production method thereof. The compound feed is compounded from the following raw materials in parts by weight: 10-20 parts of bean cakes, 15-25 parts of rapeseed cakes, 10-20 parts of cotton cakes, 10-19 parts of wheat bran, 10-15 parts of wheat middling, 10-20 parts of rice bran, 3-6 parts of shell powder, 5-10 parts of wheat meal, 4-8 parts of straw powder, 0.1-0.2 part of southernwood powder, 0.01-0.05 part of dried medlar powder, 0.1-0.2 part of vitamin b complex, 10-20 parts of liquid lactobacillus, 20-40 parts of water, 0.1-0.5 part of salt and the like. The compound feed has the advantages that 1, the nutritional ingredients and mineral substances of the pellet feed are rich and replace the original fish meal, so that the cost is reduced, an animal albumen source is obtained, and the absorption utilization ratio is high; 2, the meat quality of the grass carps is improved, the growth rate of the grass carps after eating the feed can be improved by more than 8%, the production cost of a grass carp feed is reduced by more than 5%, and the culture cost of the grass carps is reduced by more than 10%; and 3, the immunologic function of the grass carps is improved, the capabilities of preventing diseases, curing diseases and resisting viruses of the grass carps are enhanced, and the recapture rate of the grass carps can be improved by 5%.

Description

A kind of large water surface healthy aquaculture grass carp compound feed and production method thereof

Technical field

The present invention relates to the breeding feed technical field, be specifically related to a kind of large water surface healthy aquaculture grass carp compound feed and production method thereof.

Background technology

Grass carp is that the master of China's maximum supports kind, accounts for 20% of fresh-water fishes output, is also the fresh-water fishes kind that people often eat and like.The grass carp fine and tender taste, spur is few, and is nutritious, in every hectogram grass carp meat, contains protein 17.9 grams, fatty 4.3 grams, and contain multivitamin, also contains abundant unrighted acid, favourable to blood circulation, is the good food of cardiovascular patient.But how sick grass carp is, also ranks the first, and the outburst of grass carp disease also brings destructive strike often can for the cultivation in some areas.

The competition of grass carp cultivation at present mainly is feed cost and the survival rate of putting in a suitable place to breed.Due to the raising of world food price, grass carp breeding feed cost also constantly increases on the one hand; That existing mixed feed is not mainly for the immunity that improves grass carp on the other hand, can not reduce to a great extent the loss of fish death, although a lot of raisers have used antibiosis usually to reduce the illness rate of grass carp, antibioticly residual people's cognition is caused very large harm.Therefore the health-care feed that develop that a kind of cost is relatively low, comprehensive nutrition and tool strengthens grass carp immunity is that this technical field is badly in need of solving.

Summary of the invention

The deficiency that exists in order to overcome above-mentioned prior art, the invention provides a kind ofly strengthen grass carp autoimmunity, comprehensive nutrition, absorptivity is high and the production method of lower-cost healthy aquaculture grass carp compound feed and this mixed feed.

Technical scheme of the present invention is: a kind of large water surface healthy aquaculture grass carp compound feed is formed by the following raw materials in parts by weight proportioning: (content is hundred million of 5-10/ml), water 20-40 part, salt 0.1-0.5 part for soya-bean cake 10-20 part, dish cake 15-25 part, cottonseed cake 10-20 part, wheat bran 10-19 part, inferior powder 10-15 part, rice bran 10-20 part, oyster shell whiting 3-6 part, wheat flour 5-10 part, tangerine bar powder 4-8 part, sweet wormwood end powder 0.1-0.2 part, matrimony vine dry powder 0.01-0.05 part, B B-complex 0.1-0.2 part, liquid lactic acid bacterium 10-20 part.

The production method of above-mentioned grass carp compound feed, its processing step is:

The first step, proportionally take various raw materials;

Second step, the soya-bean cake in raw material, dish cake, cottonseed cake, wheat bran, inferior powder, rice bran, oyster shell whiting are mixed, add liquid lactic acid bacterium, water, putting into fermentation and filling with, 30-72h while stirring ferments under 25-65 ℃ of condition;

The 3rd step, the material that ferments in second step is taken out, under 30-65 ℃ of condition decompression air-dry to water content be 5-12%, then add wheat flour, tangerine bar powder, sweet wormwood end powder, matrimony vine dry powder, B B-complex, salt, fully mixed, make compound;

The 4th goes on foot, the blended stock granulation feed in the 3rd step is got final product.

The present invention has the following advantages: 1, this pellet nutritional labeling and mineral matter are abundant, vitamin content is abundant, adopt the fermentation of liquid lactic acid bacterium, vegetable protein is converted into animal protein, substitute original fish meal, not only reduced cost, solved the animal protein source, and its absorption rate is high; 2, add tangerine bar powder and kept the required cellulose of grass carp, when improving the grass carp meat quality, can improve the rear speed of growth of grass carp food more than 8%, reduce the feed of grass carp production cost more than 5%, reduce the grass carp aquaculture cost more than 10%; 3, the interpolation of matrimony vine dry powder and B B-complex has improved the immunologic function of grass carp, strengthen grass carp diseases prevention, cure the disease, anti-virus ability, the rate of recapture of grass carp can improve 5%.
