Abstract

The invention provides a feed additive for preventing and treating bacterial disease of pelteobagrus fulvidraco. The feed additive comprises the following raw materials in parts by weight of 20-26 parts of poria cocos, 16-24 parts of honeysuckle flowers, 25-35 parts of a dendrobium huoshanense extract, 6-12 parts of cortex eucommiae essential oil and 10-16 parts of a carrier, wherein the carrier is modified Maifan stone powder. The feed additive can effectively restrain growth of harmful pathogenic bacteria, and is notable in effects of preventing and treating bacterial gill diseases.

Description

technical field [0001] The invention belongs to the technical field of feed additives, in particular to a feed additive for preventing and treating bacterial diseases of yellow catfish. Background technique [0002] Yellow catfish mostly inhabit shallow water areas around lakes with slow-flowing aquatic plants and rivers entering the lake. They live at the bottom of the lake, especially like to live in still water or slow-flowing shoals, where there is a lot of humus and mud. The diet of yellow catfish is omnivorous. Under natural conditions, animal feed is the main feed. The fry stage feeds on zooplankton, while adult fish feed on insects and their larvae, small fish, shrimps, snails and mussels, etc., and also swallow plant debris. . Yang Caigen and others also found that the yellow catfish also devoured a large number of fertilized eggs of carp and crucian carp in March. Yu Ning and others observed that the diet of yellow catfish is relatively wide, and the composition ...
