Fish feed for preventing enteritis of Pseudobagrus fulvidraco and preparation method of fish feed

Abstract

The invention relates to fish feed and in particular relates to fish feed for preventing enteritis of Pseudobagrus fulvidraco and a preparation method of the fish feed. The fish feed for preventing enteritis of Pseudobagrus fulvidraco is prepared from the following components in parts by weight: 22-30 parts of fish meal, 7-15 parts of bran, 8-14 parts of rice bran, 1-4 parts of compound vitamin, 4-9 parts of corn meal, 6-10 parts of Chinese gall, 3-8 parts of pomegranate bark, 3-7 parts of raspberry, 3-7 parts of Chinese yam, 2-5 parts of fructus psoraleae, 2-6 parts of rhizoma galangae, 1-5 parts of dried tangerine or orange peel, 1-4 parts of malt, 2-6 parts of fish oil, 1-4 parts of honey, 1-4 parts of olive oil. The fish feed can improve the anti bacterial resistance, the fed Pseudobagrus fulvidraco has high survival rate, low feed coefficient, high specific growth rate and strong disease resisting capacity.

Description

technical field [0001] The invention relates to a fish feed, in particular to a fish feed for preventing the enteritis of the yellow catfish; the invention also relates to a preparation method of the fish feed for preventing the enteritis of the yellow catfish. Background technique [0002] Pelteobagrus fulvidraco (scientific name: Pelteobagrus fulvidraco) is a fish belonging to the genus Pelteobagrus fulvidraco. Yellow catfish, also known as yellow-cheeked fish, yellow-bone fish, yellow stickleback fish, and Helong shield fish, is distributed in the Yangtze River, Yellow River, Pearl River, Heilongjiang and other watersheds in China. . The head is large and flat, the snout is short, round and blunt, the upper and lower jaws are slightly equal in length, the mouth is large and inferior, and there are villiform tooth bands on the two faces and the palate. Eyes small, lateral. There are four pairs of barbels, the end of the nasal barbels can extend to the back of the eyes, ...

Problems solved by technology

[0003] At present, during the breeding process of yellow catfish, due to continuous fertilization and bait feeding, the remaining feces and residual bait are most likely to damage the water quality, which often causes gastrointestinal diseases in yellow catfish. The method of splashing bactericidal disinfectant is used, but the drug will more or less produce side effects or toxicity. Although it can kill pathogenic bacteria on the surface of the yellow catfish and in the water, it often causes water pollution, and long-term use will cause the drug to accumulate. , affect the health of the body, and then affect the growth rate of the yellow catfish

During the growth process, the yellow catfish often suffers from lack of resistance due to nutritional deficiencies, causing various fish gastrointestinal diseases and affecting the survival rate of yellow catfish. The compound feed for yellow catfish, which is beneficial to the growth and development of yellow catfish, is an urgent problem to be solved in the current yellow catfish aquaculture industry
