Anti-stress health-care agent for shrimp and crab

Abstract

The present invention discloses an antistress health-care preparation for shrimps and crabs. Its composition includes (by wt%) 70%-90% of glucose, 0.5%-1% of rhubarb, 0.5%-1% of garlic, 0.3%-0.5% of astragalus root, 0.3%-0.5% of forsythia fruit, 0.3%-0.5% of vitamin C and 0.3%-0.5% of vitamin E, and the rest is diluent. It can raise immunity and antistress power of aquiculture animals of shrimps and crabs, and can promote their growth. Said invention also provides the application method of said health-care preparation.

Description

technical field [0001] The invention relates to a feed for aquatic animals, in particular to a health care agent with anti-stress effect for shrimps and crabs, which can be directly sprinkled or used as a feed additive. Background technique [0002] In a high-density and intensive farming environment, aquatic animals are often subject to stress, and the function of their immune system is also damaged, so the susceptibility of aquatic animals to diseases is enhanced. In recent years, some experts and scholars at home and abroad have used immune activators to stimulate the immune system of fish and shrimp to improve the body's own defense ability and prevent the occurrence of diseases, and some progress has been made. Studies have shown that β-glucan as an immune enhancer can not only improve the anti-stress ability of fish, shrimp and crabs, but also protect them from diseases by enhancing the immunity of fish, shrimps and crabs; For groups, appropr...

Problems solved by technology

[0004] However, the above-mentioned immunopotentiators all have disadvantages such as high cost of use, unstable effect of single productive use, etc.

In our long-term research on the utilization of carbohydrates by aquatic animals, we found that adding glucose to the feed can significantly improve the stress resistance of shrimp and crabs, enhance immunity, save protein, and promote growth. This finding has not been reported.
