Feed preventing vibrio infection of xenocypris davidi and preparation method thereof

Abstract

The invention relates to a fish feed, in particular to a feed preventing vibrio infection of xenocypris davidi, and also relates to a preparation method of the mixed feed of xenocypris davidi. The feed preventing vibrio infection of xenocypris davidi comprises: by mass, 20 to 30 parts of fish meal, 8 to 15 parts of soya-bean cake, 5 to 10 parts of rapeseed meal, 6 to 12 parts of rice bran, 3 to 7 parts of hairyvein agrimony, 3 to 8 parts of cassia twig, 2 to 6 parts of perilla, 3 to 7 parts of senecio, 2 to 5 parts of calamus, 2 to 6 parts of gynura bicolor, 1 to 5 parts of prunella vulgaris, 1 to 4 parts of phellodendron, 2 to 6 parts of fish oil, 1 to 4 parts of honey, 1 to 4 parts of olive oil, and 1 to 4 parts of compound vitamin. The invention provides the feed preventing vibrio infection of xenocypris davidi according to the energy metabolism mode and nutritional requirement of the xenocypris davidi, and the feed can improve the antibiotic resistance. Moreover, the xenocypris davidi fed with the feed has low feed coefficient, high specific growth rate, and strong capability of resisting diseases.

Description

technical field [0001] The invention relates to a fish feed, in particular to a feed for preventing Vibrio yellow-tailed pomfret infection; the invention also relates to a preparation method of the above-mentioned yellow-tailed pomfret compound feed. Background technique [0002] Yellow-tailed pomfret (scientific name: Xenocyprisdavidi) is a fish of the family Cyprinidae. It is a small and medium-sized fish that grows in the middle and lower layers of freshwater bodies. It is a transverse split, with a well-developed horny edge on the lower jaw; the back is gray, the abdomen is white, there is a light yellow patch on the rear edge of the operculum, the caudal fin is orange, and it mainly feeds on plant debris, humus and algae on the bottom, ponds Breeding can be fed bran, bran, etc. [0003] At present, during the cultivation process of yellow-tailed pomfret, due to continuous fertilization and baiting, the remaining feces and residual bait are most likely to damage the wat...

AI Technical Summary

Problems solved by technology

[0003] At present, during the cultivation process of yellow-tailed pomfret, due to continuous fertilization and baiting, the remaining feces and residual bait are most likely to damage the water quality, which often causes yellow-tailed pomfret to produce Vibrio infection. When people deal with fish diseases, they often use according to The disease is treated with the method of splashing bactericidal disinfectant, but the drug will more or less produce side effects or toxicity. Although it can kill the pathogenic bacteria on the body surface of the yellow-tailed pomfret and in the water, it often causes water pollution, and long-term use will cause the drug to produce Accumulate, affect the health of the body, and then affect the growth rate of the yellow-tailed pomfret

Yellow-tailed pomfret also often causes insufficient resistance and Vibrio infection during the growth process, which affects the survival rate of yellow-tailed pomfret. Therefore, it is necessary to develop a method that can not only improve the anti-vibrio ability but also ensure the quality of feed. The yellow-tailed pomfret compound feed that is beneficial to the growth and development of the yellow-tailed pomfret is an urgent problem to be solved in the current yellow-tailed pomfret breeding industry
