Problems solved by technology

At present, in the prevention and treatment of fish diseases, the application of antibiotics and chemical drugs is still relatively common. Long-term use of antibiotics and chemical drugs will cause drug resistance and drug residues in fish, which will affect the healthy development of aquaculture.
[0003] Modern medical research shows that antibiotic residues in animal foods may change the DNA structure of the human body, resulting in serious consequences of "disabled", "teratogenic" and "carcinogenic"

Abstract

The invention provides a compound Chinese herbal medicine immunopotentiator for fish, containing by weight of: 40-50% of astragalus, 10-20% of angelica, 15-20% of glycyrrhiza, 5-10% of hawthorn, 5-12% of honeysuckle and 5-12% of isatis. Advantages of the invention is that: (1) the immunopotentiator of the invention has no adverse effect on palatability of feedstuff, (2) body immunity of culture fishes can be substantially enhanced, and immunoprotection rate to fresh water aquiculture fishes and marine culture fishes reaches to 65-71%, and (3) growth of pathogenic bacteria like escherichia coli in intestinal tract of culture fishes can be substantially restrained, growth of fish can be promoted rapidly, and weighting rate and disease resistance of culture fishes can be raised. The immunopotentiator is suitable for various of culture fishes, has a broad future, and is easy for industrialization.

Description

technical field [0001] The invention relates to a feed additive, in particular to a compound Chinese herbal immune enhancer for fish. Background technique [0002] However, with the expansion of aquaculture area and the improvement of aquaculture density, the problem of fish diseases is becoming more and more serious. At present, the application of antibiotics and chemical drugs is still relatively common in the prevention and treatment of fish diseases. Long-term use of antibiotics and chemical drugs will cause drug resistance and drug residues in fish, which will affect the healthy development of aquaculture. [0003] Modern medical research shows that antibiotic residues in animal foods may change the DNA structure of the human body, resulting in serious consequences of "disability", "teratogenicity" and "carcinogenicity". Therefore, the development of Chinese herbal medicine immune enhancer as a green substitute for antibiotics and hormone additives is of great signific...
