Additive for improving anti-oxidative stress capability of grass carp and preparation method of additive

Abstract

The invention discloses an additive for improving anti-oxidative stress capability of grass carp. The additive comprises the following raw materials in parts by weight: 20-40 parts of wheat middlings,20-32 parts of corn protein powder, 8-15 parts of bone meal, 12-20 parts of selenium-enriched yeast, 6-14 parts of chitosan, 4-9 parts of glutathione, 3-6 parts of 2-thioimidazole amino acid, 3-6 parts of resveratrol, 6-12 parts of a flavonoid compound, 10-20 parts of vitamin P, 4-11 parts of a traditional Chinese medicine premix, 3-5 parts of lactobacillus plantarum and 1-2 parts of rhodotorulamucilaginosa. According to the invention, the rhodotorula mucilaginosa is adopted to prepare active component capable of resisting oxidative stress and nutrient components for promoting growth, so that self immunity of grass carp can be enhanced, and anti-oxidative stress capability and disease resistance can be improved. Meanwhile, the feed utilization rate can be improved, water quality pollution can be reduced, and healthy growth of grass carp can be promoted.

Description

technical field [0001] The invention relates to an additive for improving the ability of grass carp to resist oxidative stress and a preparation method thereof, belonging to the technical field of feed additives. Background technique [0002] The liver is the main organ of fish material and energy metabolism, and also an important barrier organ of the body. Its detoxification and phagocytosis functions have protective effects on the body. Liver damage or lesions often lead to metabolic dysfunction and reduced disease resistance, which can easily lead to the outbreak of secondary infectious diseases. Liver diseases occur frequently in many fishes, and the etiology is complicated, but the common point is that they are all accompanied by severe oxidative stress. A variety of stress factors in the water environment, such as ammonia nitrogen, nitrite, organic poisons, and heavy metals, can cause oxidative stress and lead to liver damage in fish. Therefore, oxidative stress is c...

AI Technical Summary

Problems solved by technology

At present, most of the feed additives widely used by grass carp in the market are nutritional additives, and the use effect is not good. Therefore, it is feasible to seek an additive that can improve the ability of grass carp to resist oxidative stress, so as to enhance the immunity of grass carp itself. method
