Abstract

The invention provides a special feed for grass carps in summer. The special feed comprises the following ingredients in parts by weight: 5-15 parts of fish meal, 0-11 parts of chicken internal-organ powder, 16-30 parts of soybean meal, 15-25 parts of rapeseed meal, 8-13 parts of DDGS, 15-20 parts of wheat, 4-14 parts of rice bran and hull, 0.1-2 parts of soybean oil, 0.1-2 parts of phosphatide oil, 2-4 parts of monocalcium phosphate, 0.1-0.3 part of salt, 0.1-0.2 part of choline chloride, 1.5 parts of herbivorous fish premix and 0.05 part of a mildew-proof agent. The special feed provided by the invention has the advantages that the problems that the original feed can cause the diseases of enteritis and fatty liver and the like of the grass carps as well as increase of the death rate in summer are solved, the problems that the original feed can cause over-high ammonia nitrogen and over-low dissolved oxygen of the water-body environment are solved, and the key technical problems of low digestibility and low growth speed due to unbalanced nutrition of the original feed are broken through.

Description

A kind of grass carp special feed in summer

Technical field

The present invention relates to field of fodder, more specifically, relate to a kind of grass carp special feed in summer.

Background technology

Grass carp is the herbivorous fishes of typical case without stomach, is one of Chinese topmost cultured freshwater fish, is under the jurisdiction of Cypriniformes, Cyprinidae, Leuciscinae, grass carp genus.Comparatively strong to water temperature adaptability, can survive in 0.5 ~ 38 DEG C of water, during water temperature 27 ~ 30 DEG C, the intensity of feeding is maximum, and when 20 DEG C, food ration reduces.Region, Guangdong feed of grass carp capacity 1,100,000 tons, the scale of grass carp cultivation is in recent years increasing, and the terminal consumption market demand is day by day strong, and raiser more pursues the aquaculture model of high density, high yield, high efficiency.Summer water temperature high, Feeding in Grass Carp rate is high, scope of activities is large, and fails to select the mixed feed of applicable summer high temperature in raiser's feeding process, and the unbalanced mixed feed of nutrition of throwing something and feeding.This easily cause grass carp digest and assimilate poor, the speed of growth is slow, excreta is many, nitrogen discharged amount is high, cause water body ammonia nitrogen high, dissolved oxygen is low, and fish bulk-growth performance is affected, and severe patient is dead, and culture benefit is uncontrollable.

At present, market seldom there is the special compound feed designed for grass carp summer high temperature season specially.During summer high temperature, cultivate grass carp, raiser generally takes following Several Measures to ensure to promote that fish body grows fast.One is increase phagostimulant, lifting feedstuff feeding rate to 5-7 part; Two is low albumen mixed feeds of throwing something and feeding, and meal number of throwing something and feeding is promoted to 4-6 time by 2 times, and even 24 hours whole days are thrown something and fed; Three is high protein mixed feeds of throwing something and feeding, and reduces and throws something and feeds rate to 1-2 part.

Then under current feed, there will be following problem, grass carp there will be enteritis, fatty liver diseases, and the death rate increases; Water body environment ammonia nitrogen is high and dissolved oxygen is low; Grass carp digestibility is low, and easily liver and gall pathology occurs, anti-stress ability is poor.

Summary of the invention

The object of this invention is to provide one to use in summer high temperature season, have and improve growth performance and aquaculture cost is low, artifical compound feed balanced in nutrition.

For achieving the above object, the technical solution used in the present invention is as follows:

the artifical compound feed that a kind of grass carp summer is special, feed 100 parts of calculating with full feed, in described mixed feed various raw material and weight portion as follows: comprise domestic fish meal 5-15 part, chicken organ powder 0-11 part, 46 parts of dregs of beans 16-30 parts, add seed dish dregs of rice 15-25 part, DDGS8-13 part, wheat 15-20 part, unite chaff 4-14 part, soya-bean oil 0.1-2 part, phosphatide oil 0.1-2 part, calcium dihydrogen phosphate 2-4 part, salt 0.1-0.3 part, Choline Chloride 0.1-0.2 part, phytophage fish premix 1.5 parts, mould inhibitor 0.05 part.

In a preferred specific embodiment, in described mixed feed, various raw material and weight portion thereof comprise for domestic fish meal 11 parts, 9 parts, chicken organ powder, 46 parts of dregs of beans 19 parts, add the seed dish dregs of rice 18 parts, DDGS9 part, wheat 18 parts, system chaff 9.5 parts, 0.5 part, soya-bean oil, phosphatide oil 1 part, calcium dihydrogen phosphate 3 parts, salt 0.3 part, Choline Chloride 0.15 part, phytophage fish premix 1.5 parts, mould inhibitor 0.05 part.

In another preferred specific embodiment, in described mixed feed, various raw material and weight portion thereof comprise for domestic fish meal 7 parts, 5 parts, chicken organ powder, 46 parts of dregs of beans 27 parts, add the seed dish dregs of rice 16.5 parts, DDGS13 part, wheat 20 parts, system chaff 4.9 parts, 0.6 part, soya-bean oil, phosphatide oil 1 part, calcium dihydrogen phosphate 3 parts, salt 0.3 part, Choline Chloride 0.15 part, phytophage fish premix 1.5 parts, mould inhibitor 0.05 part.

Phytophage fish premix in the above two specific embodiment is compound vitamin many ore deposits premix that Guangzhou Haiyinte Biological Technological Co., Ltd produces.

Mix in proportion after above-mentioned raw materials is pulverized, by conventional feed machinery, after extruding cutting, namely can be made into artifical compound feed of the present invention.

According to analysis of the present invention, the concrete reason that grass carp uses existing feed to go wrong in summer is as follows:

Owing to increasing phagostimulant in existing feed, extra passive increase Feeding in Grass Carp amount, easily increase enteron aisle digestion burden, enteritis occurs, fatty liver diseases, the death rate increases; To throw something and feed low albumen mixed feed, and increase number of times of throwing something and feeding, accelerate nutrient digestion and shorten emptying time, but nutriment not fully digestion and emptying external, cause that water body environment ammonia nitrogen is high and dissolved oxygen is low; Throw something and feed high protein mixed feed, covet protein quantity, and ignore amino acid whose balance, and digestibility is low, and easily liver and gall pathology occurs, anti-stress ability is poor, and red body falls squama, not resistance to transport.

The beneficial effect that technical scheme provided by the invention is brought is: compared with grass carp traditional commerce mixed feed, the present invention has following advantages:

1, reduce the assorted dregs of rice to add, improve the material rates such as dregs of beans, domestic fish meal, chicken organ powder, promote high-quality protein quality and quantity, total amino acid especially lysine, Methionine Levels is high, meets the nutritional need that summer high temperature grass carp grows fast;

2, protein-caloric ratio balance, grass carp is high to its digestibility, water body ammonia nitrogen is low and dissolved oxygen is high.
