Abstract

The invention aims to provide a feed additive for removing the earthy taste of freshwater fish. The feed additive comprises, by weight, 5%-10% of allicin, 2%-6% of perilla leaf extracts, 2%-6% of tea polyphenols, 2%-6% of ethyl maltol, 20%-40% of yeast cell walls and 20%-40% of yeast contents. Physical, chemical and biological methods are comprehensively adopted for removing the earthy taste of the freshwater fish effectively through the feed additive, no drug tolerance or toxic and side effect is generated, and the growth rate of fishes can be remarkably increased; antioxidant capacity and immunocompetence of the fishes are improved, disease resistance of fish bodies is enhanced, fish meat quality is improved, the market price of the fishes is increased, and production effectiveness is remarkably promoted.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a feed additive for removing the earthy smell of freshwater fish and its application. Background technique [0002] Freshwater fish, whether caught naturally or farmed, have an earthy smell to varying degrees. Especially tilapia, carp, silver carp, and grass carp are the main freshwater cultured fish, and the earthy smell is particularly serious. The presence of earthy smell has a great negative impact on the taste of these fish, causing many people not to consume the above-mentioned freshwater fish. Thereby affecting the economic benefits of farmers, resulting in a reduction in the scale of farming. Therefore, the earthy smell phenomenon of freshwater fish and the technology of removing fishy smell are paid more and more attention by researchers. [0003] At present, the research on deodorization technology of freshwater fish is mainly concentrated in the fish fishing ...
