Technical Field
The invention relates to a feed for shrimps, in particular to a puffed sinking feed for promoting the health of liver and pancreas of procambarus clarkii and a preparation method thereof.
Background
Procambarus clarkii (Procambarus clarkii) named as crayfish and red crayfish belonging to the family of crayfish. It is a crustacean that grows in freshwater. With the gradual increase of the breeding density and the feed feeding amount of the procambarus clarkia, various problems begin to occur in the breeding water body environment and the shrimp body constitution, so that breeding diseases frequently occur.
The disease problem which is most concerned at present is that the liver and pancreas of the procambarus clarkii frequently have pathological changes similar to fatty liver: for example, the liver and the pancreas turn white, turn green and turn black, and even the liver tissue becomes necrotic and degenerates, which leads to the reduction and even the loss of the normal functions of the liver and the pancreas of the procambarus clarkia. The liver and pancreas, the largest and most important functional organs in the body of procambarus clarkia, has the functions of digestion, detoxification, immunity, energy storage and the like. Therefore, once the liver and pancreas are damaged, the functions of the whole organs of the procambarus clarkia are subject to collapse, which seriously affects the health and growth of the procambarus clarkia and brings great risk to the cultivation.
The current use of various antibiotics and chemical synthesis type water environment modifying agents can reduce the disease problem of Procambrus clarkii to a certain extent, but can cause a plurality of problems of drug resistance, drug residue and the like; the use of the immune vaccine is an important means for improving the disease resistance of the cultured animal body, but the practical development and development of the procambarus clarkia vaccine is not provided at present.
