Abstract

The invention discloses a rainbow trout feed additive with effects of preventing and controlling diseases and promoting growth, and a preparation method and application thereof. The feed additive is prepared from a bacillus subtilis fermenting solution. The rainbow trout feed additive with the effects of preventing and controlling diseases and promoting growth has the advantages that the healthy growth and development of rainbow trout can be obviously promoted, a body immunity function is effectively enhanced, and the bacterial disease infection can be prevented and controlled. The preparationmethod comprises the following steps of fermenting bacillus subtilis, spray-drying the fermenting solution, and mixing. The preparation method of the feed additive has the advantages that the preparation is simple, the bioavailability is high, the medicine residue is avoided, no toxic and side effects are realized, the convenience in use is realized, and the safety and reliability are realized; by adopting a biological fermenting technology, the preparation is simple, the production of three wastes is avoided in the process, and the preparation method can be widely applied to the culture of the rainbow trout.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a feed additive for rainbow trout that prevents diseases and promotes growth, a preparation method and an application thereof. 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 aqua...
