The invention discloses a preparation method of a feed capable of treating
fish gill rot diseases, and belongs to the field of feeds. According to the preparation method disclosed by the invention, purified strains having restraining effects on
aeromonas hydrophila and
edwardsiella are extracted from fresh
rheum officinale, and
fermentation culture is performed on the purified strains, so that thefeed mainly restrains
fish gill rot bacterium
cell mitochondria from
breathing and performing
electron transfer, restrains the oxidization and
dehydrogenation process of thalli
sugar and
sugar metabolism intermediate products, influences the supply of
energy resources required for vital activity of tissue cells, and is combined with
DNA to interfere template functions, restrain
protein synthesisand
nucleic acid synthesis, reduce biomembrane stability and interfere an enzymatic reaction of
energy metabolism, the effects of restraining
bacteria, sterilizing and diminishing
inflammation can beachieved, and the feed can replace antibiotic type medicines for preventing diseases from being generated, and cannot cause the yield and the quality of fish to be reduced. Through the adoption of thepreparation method disclosed by the invention, the problems that
antibiotics are added to a feed capable of treating
fish gill rot diseases at present for preventing the fish
gill rot diseases from being generated, after the feed is used for a long term,
medicine resistance can be produced, the action time of the feed for treating the fish
gill rot diseases is short, and the feed cannot protect the fish for a long term are solved.
