Non-specific immune preparation for culturing Chinese mitten crab and use method thereof

Abstract

The invention relates to a non-specific immune preparation for culturing Chinese mitten crab. The non-specific immune preparation is characterized in that each kilogram of the immune preparation comprises the following active ingredients by weight: 0.02 kg to 0.2 kg of beta-glucan, 0.06 kg to 0.5 kg of Sanhuang powder, 0.05 kg to 0.3 kg of vitamin C phosphate, 0.05 kg to 0.3 kg of peptidoglycan and 0.01 kg to 0.1 kg of allicin. According to the invention, the immunity and the breeding survival rate of Chinese mitten crabs can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of crustacean breeding, in particular to a non-specific immune preparation for breeding Chinese mitten crabs and a use method thereof. Background technique [0002] Existing studies have shown that, like other invertebrates, crustaceans lack the specific immune function of vertebrates, and their immune response depends on non-specific immune mechanisms. Non-specific immunity, antioxidant capacity and body disease resistance are important indicators to measure the non-specific immunity of crustaceans. The non-specific immunity of Chinese mitten crab has been proved by many scholars, which provides the physiological basis and conditions for non-specific immune agents to play a role in Chinese mitten crab. The types of non-specific immune preparations include: polysaccharide preparations derived from microorganisms, Chinese herbal medicine preparations derived from animals and plants, nutritional factor anti-s...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many functional studies and application techniques on a single type of non-specific immune substances. The play of animal immunity plays an important regulatory role, which can significantly improve the hemolymph phagocytic activity, serum lytic activity, acid phosphatase, alkaline phosphatase, serum The activity of phenol oxidase and superoxide dismutase can promote the immune function of the body; however, microbial polysaccharides do not have the effect of increasing the body's anti-stress ability

(2) Chinese herbal medicines and their extracts can significantly improve the non-specific immunity of carp, Jian carp, and heterogeneous gibel carp, such as lysozyme activity and white blood cell function, and have obvious antibacterial effects. The use will not lead to drug resistance or the accumulation of residues in the drug, and is beneficial and harmless to humans or other animals, showing its potential as an immune enhancer in aquatic animal farming; however, the anti-stress effect is not obvious

(3) Nutritional factor anti-stress substances (including vitamin C, vitamin E, vitamin K, vitamin A, etc.) can significantly improve the anti-stress ability of farmed animals, enhance the disease resistance of fish, and maintain the normal metabolic function of farmed animals and optimal health; however, its non-specific immune effects are not significant

Therefore, non-specific immune compound preparations may become biologically active substances to replace traditional antibiotics, but there is still a lack of research on the impact of non-specific immune compound preparations on the immune response of cultured Eriocheir sinensis. Microbial polysaccharides, Chinese herbal medicines, anti-stress substances and other non-specific immune substances are compounded as raw materials, but the prepared non-specific immune compound preparations often cannot fully utilize the advantages of each raw material component, and the application effect is often limited, and different components and ratios are prepared. The prepared compound preparations are very different
