Problems solved by technology

[0010] However, in the existing published literature, good control effects cannot be achieved when applied to freshwater rainbow trout cultured in mountainous areas of Guangxi. A large number of rainbow trout die after being infected with bacteria, which causes great troubles to farmers and greatly reduces the need for farmers to continue. breeding enthusiasm

Abstract

The invention discloses a feed additive for improving disease resistance of rainbow trout. The feed additive is prepared from hairyvein agrimony, aristolochia debilis, semen lepidii, humifuse euphorbia herb, herba epimedii, tuber fleeceflower stem, grifola, dutchmanspipe root, parasitic loranthus, herba epimedii, human placenta, dipsacus root, honeysuckle, gynostemma pentaphylla, fritillaria and acompound microbial agent. The feed additive provided by the invention follows the principles of Chinese veterinarians, can improve the immunity of fish bodies, enables rainbow trout to effectively resist the interference of external factors, can perfect and improve a system for preventing and resisting diseases of rainbow trout, and achieves the purposes of preventing diseases before illness andpreventing and treating diseases after illness. No chemical raw material is added into the feed additive, so that the use of a large amount of antibiotics in the rainbow trout breeding process is avoided, the environmental pollution is reduced, the morbidity and mortality of rainbow trout can be greatly reduced, and the bred rainbow trout meat is safer and better in quality.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed additives, and in particular relates to a feed additive for improving the disease resistance of rainbow trout, a preparation method and an application. Background technique [0002] my country is a big aquaculture country in the world, and the output of freshwater products ranks first in the world. In 2005, the total output of aquatic products in the country was 51.076 million tons, the output value of aquatic products was 401.61 billion yuan, and the breeding volume of aquatic products reached 33.95 million tons, accounting for 66.48% of the total output of aquatic products. As my country's freshwater fish go abroad one after another and open up overseas markets, the development space of freshwater aquaculture will be wider, and the proportion of aquatic product aquaculture will further increase, and aquatic product aquaculture will become the main driving force for the growth of aquatic pro...
