Compound feed capable of improving fatty liver and body colour of marine fish and preparation method thereof

Abstract

The invention provides a compound feed capable of improving the fatty liver and body colour of the marine fish. The compound feed comprises a premixed feed, a bile acid, curcumin and betaine, wherein the premixed feed comprises fish meal, soya bean meal, corn gluten meal, high protein flour, corn, shrimp shell meal, monocalcium phosphate, fish oil, liquid phosphatide, vitamin premixes, mineral premixes, and the like. Artificial marine-fish breeding experiments prove that the compound feed provided by the invention can meet the nutritional needs of marine-fish growth, effectively enhance the physique of the marine fish, improve the immunity of the marine fish, reduce the incidence of a fatty liver disease, and improve the body color of the marine fish, so that the body color of the marine fish is bright-colored and close to a wild natural color, thereby enhancing the quality of artificially cultured marine fish.

Description

technical field

[0001] The invention relates to an animal feed, in particular to a seawater fish feed. Background technique

[0002] At present, the quality of artificially bred sea fish is poorer than that of wild sea fish living in nature. The main manifestations are that the skin color of the fish body is lighter, the amount of crude protein in the muscle is reduced, the ratio of essential amino acids in protein, the index of essential amino acids, and the protein The three indicators are all lower, but its body fat content is higher than that of wild sea fish. At the same time, the taste of artificially farmed sea fish products is not as delicious as that of wild sea fish. Among them, the most important influencing factor is the selection of fish feed. However, there is currently no feed that can effectively prevent and improve the fatty liver problem of artificially cultured sea fish and increase the body color of adult fish.
