Problems solved by technology

The fat content in coho salmon feed is about 20%. During the breeding process, it often causes liver hypertrophy and increased liver fat droplets. In severe cases, liver tissue necrosis will occur, seriously affecting its growth and health, resulting in high mortality and slow growth during the breeding process. The problem

Abstract

The invention discloses a feed additive for liver and gallbladder protection of silver salmon and a preparation method thereof. The feed additive comprises the following raw materials in parts by weight: 20-30 parts of choline chloride, 15-25 parts of betaine, 10-20 parts of bile acid, 10-20 parts of inositol, 5-12 parts of carnitine, 5-12 parts of vitamins and 5-10 parts of natural astaxanthin. The preparation method comprises the following steps of: weighing the above components in proportion, uniformly mixing the components, crushing the components by an ultrafine grinder, and sieving the components by a 150-mesh sieve to prepare the powdery feed additive for liver and gallbladder protection. The feed additive can effectively prevent liver and gallbladder diseases such as fatty liver, improve absorption and metabolism of nutrient substances such as fat by silver salmon, protect liver and gallbladder health, effectively remove free radicals in silver salmon, improve the antioxidant ability, immunity and anti-stress ability of the body, improve the survival rate, promote healthy growth of silver salmon and improve the quality, thereby improving the economic benefits of silver salmon breeding.

Description

technical field [0001] The application relates to the technical field of feed additives and preparation methods thereof, in particular to a liver-protecting and gallbladder-protecting feed additive for coho salmon and a preparation method thereof. Background technique [0002] Coho salmon, also known as coho salmon, belongs to Herringformes, Salmonidae, and Salmon. After growing into adult fish, they migrate to fresh water to lay eggs to complete their growth cycle. The flesh of coho salmon is bright orange and has a good taste, which can arouse people's appetite. It is an excellent raw material for sashimi and other delicacies. It is rich in unsaturated fatty acids, which can effectively prevent various cardiovascular and cerebrovascular diseases, diabetes and other diseases. Accordingly, some provinces in Canada are funded by the government to make public service advertisements on TV, suggesting that people eat more cold water such as coho salmon Coho salmon is used to pr...
