Feed additive for improving immunity of freshwater fish and preparation method thereof

Abstract

A feed additive for improving immunity of freshwater fish comprises the following components by weight: 650-700 parts of fly maggot powder, 200-300 parts of seabuckthorn seed protein powder, 120-130 parts of carboxymethyl micropore corn starch, 100-120 parts of seabuckthorn leaf powder, 40-60 parts of seabuckthorn flavone of 10%, 1-2 parts of saccharomycete powder and 1-2 parts of lactic acid bacteria powder. The invention further provides a preparation method of the feed additive, which comprises the following steps: (1) using water to dissolve seabuckthorn flavone into 65%-75%solution, adding the carboxymethyl micropore corn starch, and evenly mixing to obtain a mixture; (2) warming a drying device in advance to 60-80 DEG C, placing the mixture prepared in the step (1) in the drying device for drying, grinding to exceed 100 meshes, and obtaining seabuckthorn flavone after embedding treatment; and (3) placing the fly maggot powder, the seabuckthorn seed protein powder, the seabuckthorn leaf powder, seabuckthorn flavone after embedding treatment, saccharomycete and the lactic acid bacteria powder in a mixing container, and evenly mixing. The feed additive can remarkably improve organism immunocompetence and nutrition level of the freshwater fish and improves disease-resistant capability of the freshwater fish.

Description

technical field

[0001] The invention relates to a feed additive capable of enhancing the immunity of freshwater fish and a preparation method thereof. Background technique

[0002] my country has a vast territory, inland rivers and rivers, and lakes and reservoirs dotted around. It is one of the countries with the most fresh water in the world. The total amount of aquatic product farming accounts for 70% of the world's total aquatic product farming, and the freshwater fish farming output accounts for about 70% of the world's fresh water. 73% of total fish farming production. In recent years, my country's freshwater fish industry has developed rapidly, and its total aquaculture production has accounted for 65% of my country's total fish production, becoming the pillar industry of my country's fishery economy. According to statistics in 2010, the total output of bulk freshwater fish in my country was 16.234 million tons, accounting for 69.2% of the total freshwater aquaculture...

Examples

Embodiment 1

[0038] (1) Dissolve 20kg of 10% seabuckthorn flavonoids in 30kg of water to obtain a solution with a concentration of 66.67%, then add 60kg of carboxymethyl microporous cornstarch and stir to obtain a mixture.

[0039] (2) Preheat the drying equipment to 60 degrees Celsius, then put the mixture prepared in step (1) into drying, and pulverize through 100 mesh to obtain embedding-treated seabuckthorn flavonoids.

[0040] (3) Put 325kg of fly maggot powder, 100kg of seabuckthorn seed protein powder, 50kg of seabuckthorn leaf powder, embedding processed seabuckthorn flavonoids, 0.5kg of yeast powder and 0.5kg of lactic acid bacteria powder into a stirring container and stir evenly to obtain this product additive.

[0041] The prepared additive can be used after being mixed with freshwater fish feed at a weight ratio of 10%, which can obviously improve the body immunity and nutritional level of freshwater fish and the disease resistance of freshwater fish.

Embodiment 2

[0043] (1) Dissolve 30kg of 10% seabuckthorn flavonoids in 40kg of water to obtain a solution with a concentration of 75%, then add 65kg of carboxymethyl microporous cornstarch and stir to obtain a mixture.

[0044] (2) Preheat the drying equipment to 80 degrees Celsius, then put the mixture prepared in step (1) into drying, and pulverize through 100 mesh to obtain embedding-treated seabuckthorn flavonoids.

[0045] (3) Put 350kg of fly maggot powder, 150kg of seabuckthorn seed protein powder, 60kg of seabuckthorn leaf powder, embedding processed seabuckthorn flavonoids, 1kg of yeast powder and 1kg of lactic acid bacteria powder into a stirring container and stir evenly to obtain the additive.

[0046] The prepared additive can be used after being mixed with freshwater fish feed at a weight ratio of 10%, which can obviously improve the body immunity and nutritional level of freshwater fish and the disease resistance of freshwater fish.

Embodiment 3

[0048] (1) Dissolve 50kg of 10% seabuckthorn flavonoids in 77kg of water to obtain a solution with a concentration of 65%, then add 125kg of carboxymethyl microporous cornstarch and stir to obtain a mixture.

[0049] (2) Pre-heat the drying equipment to 75 degrees Celsius, then put the mixture prepared in step (1) into drying, and pulverize through 100 mesh to obtain embedding-treated seabuckthorn flavonoids.

[0050] (3) Put 680kg of fly maggot powder, 250kg of seabuckthorn seed protein powder, 110kg of seabuckthorn leaf powder, embedding processed seabuckthorn flavonoids, 1.5kg of yeast powder and 1.5kg of lactic acid bacteria powder into a stirring container and stir evenly to obtain this product additive.

[0051]The prepared additive can be used after being mixed with freshwater fish feed at a weight ratio of 10%, which can obviously improve the body immunity and nutritional level of the freshwater fish and the disease resistance of the freshwater fish.
