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.
