Abstract

The present invention discloses a fish feed rich in nutrition and a preparation method thereof. The fish feed rich in nutrition is characterized by consisting of the following raw materials in parts by weight: 40-60 parts of corn flour, 20-30 parts of bran, 20-30 parts of soybean meal, 5-10 parts of fly maggot powder, 0.5-0.8 part of compound vitamin, 10-15 parts of attractants, and 5-8 parts of microbial compound bacteria. The attractants are products of one or more of betaine, garlic powder and cooking oil. The microbial compound bacteria include photosynthetic bacteria, bacillus subtilis, bacillus licheniformis, rhodopseudomonas palustris and denitrifying bacteria. By adding the microbial compound bacteria of the photosynthetic bacteria, bacillus subtilis, bacillus licheniformis and rhodopseudomonas palustris into the fish feed, the fish feed can increase the absorption of the fish to nutrients, at the same time can play a good role in purifying water quality, and thus increase the immunity and survival quantity of the fish.

Description

A kind of nutritious fish meal and preparation method

[technical field]

The technical field of fish meal of the present invention, a kind of nutritious fish meal and the skill of preparation method Art field.

[background technology]

Along with the appearance of Aquatic product intensive culture, cultivation density is greatly improved, cause in water body residual ear and Animal excrements are increased, and under such environmental condition, promote the excess breeding of harmful algae, COD in water, Ammonia-nitrogen content rises, and dissolved oxygen amount declines, thus states and make the quantity in stock of fish gradually decrease, in existing fish meal, Typically not comprising the microorganism that can purify water and contribute to fish absorption nutrient substance, the most existing fish is raised Material can only play the effect providing nutrition, and can not increase the immunocompetence of fish and increase the effect of fish survival volume.

[summary of the invention]

The purpose of the present invention solves the problems of the prior art exactly, propose a kind of nutritious fish meal and Preparation method, the present invention, by adding compound vitamin in fish meal, is increasing fish to absorption of nutrient ingredients While, the injury that fish tape is come by heavy metal element can be effectively reduced again；The present invention raises also by fish Material with the addition of micro-life of photosynthetic bacteria, bacillus subtilis, Bacillus licheniformis and Rhodopseudomonas palustris Thing compound bacteria, thus increase fish to absorption of nutrient ingredients while, can play again well to purify water Effect, and then add immunocompetence and the survival volume of fish.

For achieving the above object, the present invention proposes a kind of nutritious fish meal, it is characterised in that press Following parts by weight proportioning includes: Semen Maydis powder 40-60 part, wheat bran 20-30 part, soybean cake 20-30 part, fly larvae Powder 5-10 part, compound vitamin 0.5-0.8 part, food calling material 10-15, microbial composite bacteria 5-8 part are described Food calling material is the product of one or more mixing of glycine betaine, Bulbus Allii powder and edible oil, and described microorganism is combined Bacterium includes that photosynthetic bacteria, bacillus subtilis, Bacillus licheniformis, Rhodopseudomonas palustris and denitrification are thin Bacterium.

As preferably, described a kind of nutritious fish meal, include by following parts by weight proportioning: Semen Maydis Powder 50-60 part, wheat bran 25-38 part, soybean cake 20-25 part, fly maggot powder 8-10 part, compound vitamin 0.6-0.8 Part, food calling material 10-12 part, microbial composite bacteria 6-8 part.

As preferably, described compound vitamin be include vitamin A, vitamin C, vitamin E compound Cellulose.

As preferably, the preparation method of a kind of nutritious fish meal, it is characterised in that include walking as follows Rapid: a) early stage processes: is added by soybean cake and carries out pulverization process in pulverizer；

B) preparation of microbial composite bacteria: first to photosynthetic bacteria, bacillus subtilis, Bacillus licheniformis, Rhodopseudomonas palustris and denitrifying bacteria are respectively put in culture medium respectively and cultivate, thus obtain one-level Strain liquid, then puts into first class inoculum liquid in fermentation tank and ferments, thus obtain second class inoculum liquid, After second class inoculum liquid is carried out spray drying treatment；

C) dispensing: by following parts by weight: Semen Maydis powder 40-60 part, wheat bran 20-30 part, soybean cake 20-30 part, Fly maggot powder 5-10 part, compound vitamin 0.5-0.8 part, food calling material 10-15, microbial composite bacteria 5-8 part are entered Row dispensing；

D) batch mixing: add water in the raw material that step c) prepares, and be uniformly mixed；

Pelletize: the raw material that step d) is mixed, add in granulator and carry out briquetting granulation.

As preferably, the described step b) temperature when carrying out first class inoculum liquid and cultivating is 30 DEG C-34 DEG C, Described step b) ph value of used culture medium when carrying out first class inoculum liquid and cultivating is 7.5-8.5, during cultivation Between be 3-4 days.

As preferably, the described step b) culture medium when fermentation cylinder for fermentation is beef-protein medium, The described step b) temperature when being spray-dried is 50 DEG C-60 DEG C.

[detailed description of the invention]

A kind of nutritious fish meal of the present invention, it is characterised in that include by following parts by weight proportioning: Semen Maydis Powder 40-60 part, wheat bran 20-30 part, soybean cake 20-30 part, fly maggot powder 5-10 part, compound vitamin 0.5-0.8 Part, food calling material 10-15, microbial composite bacteria 5-8 part, described food calling material is glycine betaine, Bulbus Allii powder and eats Oil one or more mixing product, described microbial composite bacteria include photosynthetic bacteria, bacillus subtilis, Bacillus licheniformis, Rhodopseudomonas palustris and denitrifying bacteria, described a kind of nutritious fish meal, It is characterized in that, include by following parts by weight proportioning: Semen Maydis powder 50-60 part, wheat bran 25-38 part, soybean cake 20-25 part, fly maggot powder 8-10 part, compound vitamin 0.6-0.8 part, food calling material 10-12 part, microorganism are multiple Closing bacterium 6-8 part, described compound vitamin is the composite fibre including vitamin A, vitamin C, vitamin E Element, the preparation method of a kind of nutritious fish meal is characterized in that, comprises the steps: that a) early stage processes: Soybean cake is added pulverizer carries out pulverization process；B) preparation of microbial composite bacteria: first to photosynthetic bacteria, Bacillus subtilis, Bacillus licheniformis, Rhodopseudomonas palustris and denitrifying bacteria are respectively put into training respectively Support in base and cultivate, thus obtain first class inoculum liquid, then first class inoculum liquid is put in fermentation tank and carry out Fermentation, thus obtain second class inoculum liquid, finally second class inoculum liquid is carried out spray drying treatment；C) dispensing: press Following parts by weight: Semen Maydis powder 40-60 part, wheat bran 20-30 part, soybean cake 20-30 part, fly maggot powder 5-10 Part, compound vitamin 0.5-0.8 part, food calling material 10-15, microbial composite bacteria 5-8 part carry out dispensing；D) mixed Material: add water in the raw material that step c) prepares, and be uniformly mixed；E) pelletize: by step d) The raw material mixed, adds in granulator and carries out briquetting granulation, and described step b) is carrying out first class inoculum liquid training Temperature when supporting is 30 DEG C-34 DEG C, and described step b) is used culture medium when carrying out first class inoculum liquid and cultivating Ph value be 7.5-8.5, incubation time is 3-4 days, and described step b) is when fermentation cylinder for fermentation Culture medium is beef-protein medium, and the described step b) temperature when being spray-dried is 50 DEG C -60℃。
