Abstract

The invention discloses a feed additive for promoting fish intestinal micro-ecological restoration, a preparation method and application, and belongs to the technical field of microorganism application. The feed additive comprises intestinal contents separated from fish intestinal tissues, and the thallus content of the intestinal contents is 1 * 10<10>-1 * 10<12> / mL. The application of the feed additive comprises any one of the following: 1) repairing fish intestinal structure damage caused by antibiotics; and 2) improving the structural composition of the fish intestinal flora. According to the invention, the feed additive is prepared by extracting intestinal contents from fish intestinal tissues, the fish additive is added into a fish feed to improve the fish intestinal structure damage and intestinal flora disorder caused by use of antibiotics, the immunity of fishes can be improved, the use of antibiotics can be reduced, and sustainable development of aquaculture or ornamental fishery is realized.

Description

technical field

[0001] The invention relates to the technical field of microbial application, and relates to a feed additive for promoting the recovery of fish intestinal microecology, a preparation method and an application. Background technique

[0002] In recent years, the rapid development of my country's aquaculture industry has produced huge economic and social benefits. However, with the continuous expansion of aquaculture scale, the frequent occurrence of diseases caused by various pathogens poses a huge threat to the sustainable development of aquaculture. At present, the use of antibiotics to prevent and control fish bacterial diseases is still the main way to prevent and control them, but long-term use will lead to problems such as drug residues and pathogenic bacteria developing drug resistance. Not only that, the use of antibiotics will also significantly affect the composition and diversity of intestinal microorganisms, leading to intestinal microecological di...
