Problems solved by technology

[0004] Existing studies have shown that the mechanism of nutritional fatty liver formation: on the one hand, the ability of liver cells to synthesize triglycerides is enhanced due to high-energy feeding; on the other hand, cellular mitochondrial dysfunction leads to oxidative phosphorylation and β - Reduced oxidation, resulting in reduced fatty acid decomposition; thirdly, due to obstacles in the transport of fat synthesized in the liver, endogenous fat cannot be normally transported out of cells and deposited in liver cells. Related studies have also shown the appearance of fatty liver related to changes in the amount of apolipoproteins in the liver

Embodiment 1

[0020] The preparation method of the pretreated shrimp shell is:

[0021] After crushing the shrimp shells, add them to 10wt% sodium bicarbonate solution for immersion treatment for 6 hours, then wash them with clear water until neutral, then add the washed shrimp shell powder into 4wt% polyvinyl alcohol solution and stir evenly, then Add silica sol, fully react at 160°C, filter after the reaction, and dry the filtrate. The ratio of the mass of silica sol to the mass of shrimp shell powder is 1:8.

[0022] The preparation method of yeast extract is:

[0023] 1) Use active yeast as raw material, add water to it for beating treatment, adjust the pH to 6.5 after the temperature of the slurry is raised to 53°C, and then add yeast extract enzyme, mannanase and neutral protease compound enzyme I in sequence to carry out enzymatic Solution and ultrasonic treatment at the same time, the reaction time is 9h;

[0024] 2) After cooling the enzymolysis solution in step 1) to 48°C, adju...

Embodiment 2

[0026] The preparation method of the pretreated shrimp shell is:

[0027] After crushing the shrimp shells, add them to 16wt% sodium bicarbonate solution for soaking treatment for 4 hours, then wash them with clear water until neutral, then add the washed shrimp shell powder into 7wt% polyvinyl alcohol solution and stir evenly, and then Add silica sol, fully react at 110°C, filter after the reaction, and dry the filtrate. The ratio of the mass of silica sol to the mass of shrimp shell powder is 1:5.

[0028] The preparation method of yeast extract is:

[0029] 1) Use active yeast as raw material, add water to it for beating treatment, adjust the pH to 7.2 after the temperature of the slurry is raised to 62°C, and then add yeast extract enzyme, mannanase and neutral protease compound enzyme I in sequence to carry out enzymatic Solution and ultrasonic treatment at the same time, the reaction time is 13h;

[0030] 2) After cooling the enzymolysis solution in step 1) to 43°C, a...

Embodiment 3

[0032] A feed additive for raw fish, calculated by weight percentage, comprising the following raw materials:

[0033] 36 parts of pretreated shrimp shells of Example 1, 20 parts of yeast extract of Example 1, 14 parts of ginger oil, 10 parts of porous starch and 15 parts of zeolite powder.

Abstract

The invention provides a feed additive for snakeheaded fish. The feed additive comprises the following raw materials in parts by weight of 30-40 parts of pretreated shrimp shells, 16-26 parts of a yeast extract. 10-18 parts of ginger oil, 7-14 parts of porous starch, and 13-17 parts of zeolite powder. The additive can be directly added to feeds, so that the immunity of the snakeheaded fish can beimproved, the generation rate of liver diseases can be reduced, and the survival rate can be increased.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a feed additive for raw fish. Background technique [0002] "Raw fish" can refer to snakehead, commonly known as black fish. It is ferocious by nature, has strong reproductive ability, and has a huge appetite. It can often eat all other fish in a certain lake or pond, even its own young fish. Black fish can also glide on land, migrate to other waters to find food, and can live away from water for as long as 3 days. It is the "dish on the plate" of the Chinese. In recent years, in order to meet the needs of domestic and foreign consumer markets, many areas have carried out scientific research and breeding practices of artificially raised raw fish, and accumulated a lot of successful experience, especially the breakthroughs in seed breeding technology and artificially compounded special feeds. The fish farming industry has laid the foundation for commercialization and lar...
