Abstract

The invention provides a special feed additive for tilapia that resists diseases and increases production. The feed additive is the water extract of nanzhuzizi, which can enhance the immune level of tilapia and improve its survival rate and production. At the same time, the raw material of the feed additive is The source is stable, the price is cheap and efficient, the preparation method is simple, and it is natural, non-toxic and residue-free, and can reduce the use of antibiotics and chemical drugs.

Description

technical field [0001] The invention belongs to the technical field of feed additives for aquatic fish, and in particular relates to a special feed additive for tilapia that resists diseases and increases production. Background technique [0002] Tilapia is one of the excellent species promoted by the Food and Agriculture Organization of the United Nations to the whole world. In 2010, my country's tilapia aquaculture production accounted for 39.2% of the world's total production, becoming the leading product of my country's freshwater aquatic product exports. However, with the development of high-density intensive aquaculture, various fish diseases occur frequently, causing huge economic losses. The prevention and treatment of fish diseases mainly includes the use of drugs such as antibiotics for treatment and preventive immunity. Although antibiotics can effectively control the occurrence of a variety of fish diseases, they also lead to the emergence of drug-resistant str...
