Abstract

The invention discloses a protein recipe in a fish feed. The feed comprises a single protein raw material of which the protein content is 30%, bean protein of which the purity is 45-55%, and oil protein of which the purity is 50-60%; the protein comprises animal protein of which the purity is 35-40%; the animal protein is composed of fish meal, meat meal and silkworm chrysalis meal; the bean protein comprises soybean meal and raw soybean flour. The method is low in cost, safe, environment-friendly, and abundant in nutrition.

Description

Protein prescription in fish feed

Technical field

The present invention has the formula about protein part in the feed in aquaculture, particularly feed.

Background technology

See with regard to current reality, the quantity variance of China's fresh-water fishes mixed feed nutritive index is very large, the difference being China different regions is on the one hand very large, and be that the actual standard difference of different enterprise is very large on the other hand, the difference of breed varieties different is besides very large.

In aquaculture production practice, feed is most important for cultivation industry.It is not only different types of aquatic species and provides nutrition, and it also affects water quality among long-term existence water body.As wherein contained: the nutritional labeling of protein, fat.

Protein raw material is the core of mixed feed quality, and in aquatic product matched feed, the choice and operation of protein raw material is also the key point of control of product quality and Product Cost Control.Their use had both determined the product quality of mixed feed, also determined the product price of mixed feed.

The disease of common aquaculture, is simply thought it is because forage compounding not appropriate in breeding process substantially, usually because in cultivation, daily ration, feeding quantity is excessive; Or directly use grouts, chilled nursing, superfluous residual feed becomes expensive fertilizer, causes ammonia nitrogen in pond too high.

How to ensure the nutrition of fish, avoid again waste and polluted-water, its problem mainly considered comprises: the actual cultivation, utilizing status etc. of protein quality quantity, amino acid whose counterbalance effect and selected protein raw material.

Summary of the invention

For solving the problems of the technologies described above, the invention provides the protein prescription in a kind of fish feed, described fish are freshwater fish, wherein: described feed is the single protein raw material of protein content 30%, and described albumen is by the animal protein of 35 ~ 40% purity, described animal protein by: fish meal, digested tankage and dried silkworm chrysalis meal form; The peas protein of 45 ~ 55% purity, described peas protein by: Soybean Meal and bredsoy form; Form with the oils albumen of 50% ~ 60% purity.

Aquaculture feed protein component provided by the present invention is high, and cost is low, the normal growth nutrition that ensure that fish, reduces the discharge of ammonia nitrogen refuse simultaneously, is conducive to purifying water body, ensures the oxygen content in water, reduces the probability of viral communication.

Detailed description of the invention

The invention provides the protein prescription in a kind of fish feed, described fish are freshwater fish, and described feed is the single protein raw material of protein content 30%, wherein said albumen is by the animal protein of 35 ~ 40% purity, the peas protein of 45 ~ 55% purity, and the oils albumen composition of 50% ~ 60% purity.

This feed has higher animal protein, also has oils albumen and soybean protein simultaneously.While guarantee nutriment, nitrate and hydrogen sulfide material in water quality should be reduced, avoid the eutrophication harmful substance because the materials such as feed cause.

In the present invention, the protein content of feed is 30%, and it can meet the growth needs of overwhelming majority cultivation.And protein quality quantity wherein, amino acid whose balance, avoid waste and the eutrophication of ammonia nitrogen, be conducive to the growth of freshwater fish, there is stronger low-cost advantage.

As preferred described mode, described freshwater fish comprises: carp, crucian carp, silver carp, flathead, grass carp, triangular bream, non-crucian carp, Colossoma brachypomum or catfish.

As the preferred embodiments of the present invention, described animal protein by: fish meal, digested tankage and dried silkworm chrysalis meal form, and the content ratio between three is: 1:0.3:0.5.The feature that it has low cost, hazardous substance lowers, also reduces the generation of the generation of harmful nitrogen oxygen compound, harmful inorganic salts, ensures the clean of water body.

As the preferred embodiments of the present invention, described peas protein comprises: Soybean Meal and bredsoy, and its content is therebetween than being 1:0.4 ~ 0.7.It effectively can adjust the compositions such as amino acid, and reduces the decomposition of ammonia nitrogen substances.

As the preferred embodiments of the present invention, described oils albumen comprises: the mixture of sesame seed meal, rapeseed dregs, peanut meal and cotton dregs.This formula provides supplementing of fat content while can ensureing protein, be conducive to fish growth.

Feed provided by the present invention, while providing abundant protein and amino acid nutrient, avoid the decomposition of oxynitrides in water quality to produce, and cost is low, the protein formulations in the feed of suitable especially freshwater fish.

Should be appreciated that invention which is intended to be protected is not limited to non-limiting embodiments, should be appreciated that non-limiting embodiments is described as just example.The protection domain of the essence that the application will require more is embodied in the scope that independent claims provide, and its dependent claims.
