Embodiment 1

[0027] The gold pomfret feed of Example 1 is prepared from the following raw materials in proportions by mass: 15 parts of fish meal, 15 parts of rapeseed protein concentrate, 10 parts of flour, 2 parts of brewer's yeast, 2 parts of lecithin, and 2 parts of fish oil , 0.5 parts of vitamins and minerals for fish, 0.5 parts of calcium hydrogen phosphate.

[0028] The above rapeseed protein concentrate is prepared through the following steps:

[0029] S101. After the rapeseed cake raw material is pulverized and pretreated, the material with a particle diameter of 10 meshes is obtained, which is put into the stirring filter tank of the rapeseed cake detoxification reaction, and then water and auxiliary materials at 50°C to 55°C are added to carry out Stir and react, then stand still; the auxiliary material is calcium chloride, and its weight ratio is 0.1% of rapeseed cake;

[0030] S102, add clear water and hydrochloric acid, the quality of hydrochloric acid is 3% of the quality ...

Embodiment 2

[0035] The gold pomfret feed of Example 2 is prepared from the following raw materials in proportions by mass: 20 parts of fish meal, 20 parts of rapeseed protein concentrate, 15 parts of flour, 4 parts of brewer's yeast, 4 parts of lecithin, and 4 parts of fish oil , 1 part of fish vitamins and minerals, 1 part of calcium hydrogen phosphate.

[0036] The above rapeseed protein concentrate is prepared through the following steps:

[0037] S201. After the rapeseed cake raw material is pulverized and pretreated, the material with a particle diameter of 9 meshes is obtained, which is put into a stirred filter tank for the rapeseed cake detoxification reaction, and then water and auxiliary materials at 55°C to 60°C are added to carry out Stir and react, then stand still; the auxiliary material is calcium chloride, and its weight ratio is 0.2% of rapeseed cake;

[0038] S202, add clear water and sulfuric acid, the quality of sulfuric acid is 3.5% of the quality of rapeseed cake, a...

Embodiment 3

[0043] The gold pomfret feed of Example 3 is prepared from the following raw materials in proportions by mass: 25 parts of fish meal, 25 parts of rapeseed protein concentrate, 20 parts of flour, 6 parts of brewer's yeast, 6 parts of lecithin, and 6 parts of fish oil , 2 parts of vitamins and minerals for fish, 2 parts of calcium hydrogen phosphate.

[0044] The above rapeseed protein concentrate is prepared through the following steps:

[0045] S301. After the rapeseed cake raw material is pulverized and pretreated, the material with a particle diameter of 8 meshes is obtained, which is put into the stirring filter tank for the detoxification reaction of the rapeseed cake, and then water and auxiliary materials at 60°C to 65°C are added to carry out Stir and react, then stand still; the auxiliary material is calcium chloride, and its weight ratio is 0.25% of rapeseed cake;

[0046]S302, adding clear water and phosphoric acid, the quality of phosphoric acid is 4% of the qualit...

Abstract

The invention discloses a golden pompano feed, relating to the field of aquatic product raising. The golden pompano feed is prepared from the following raw materials in parts by weight: 15-40 parts of fish powder, 15-40 parts of rapeseed protein concentrates, 10-30 parts of flour, 2-10 parts of beer yeast, 2-10 parts of lecithin, 2-10 parts of fish oil, 0.5-5 parts of vitamins and minerals for fish and 0.5-5 parts of calcium hydrophosphate. The golden pompano feed has the following advantages that the golden pompano feed can effectively improve the survival rate of golden pompanos and weight percent gain in the later breeding period and reduce the feed coefficient in the later breeding period while meeting all the nutritional requirements of golden pompano breeding; and the use amount of fish powder in the feed is obviously lower than that in the conventional golden pompano feeds on the market at present, so the cost of the feed can be obviously reduced.

Description

technical field [0001] The invention relates to the field of aquatic product breeding, in particular to a gold pomfret feed. Background technique [0002] Golden pomfret fish is white and tender, and it is a valuable high-grade edible seawater fish. my country has a vast sea area and has favorable conditions for golden pomfret farming. It not only attracts attention in the domestic market, but also in the United States, Japan, South Korea, the European Union and other major aquatic product consumption countries, the supply is in short supply. At present, with the continuous expansion of the golden pomfret breeding scale and the continuous improvement of the degree of intensification, the requirements for artificial compound feed are getting higher and higher, and the market is in urgent need of efficient, environmentally friendly, safe and reliable high-quality compound feed. At present, the survival rate of artificially cultured golden pomfret is generally less than 80%, t...
