Preparation process of grass carp feed additive containing eucommia bark powder

Abstract

The invention relates to a preparation process of a grass carp feed additive containing eucommia bark powder. The feed additive contains multiple traditional Chinese medicine ingredients, natural and safe Chinese herbal medicine ingredients are selected according to the growth characteristics, susceptibility to disease and eating habit of a grass carp, and the variety and the best dosage of Chinese herbal medicine are finally determined through repeated test and verification following the preparation principle of sovereign, minister, assistant and courier, so that synergistic interaction and mutual promotion of the traditional Chinese medicine ingredients are realized, and the technical effects of better growth promotion and immunity improvement are achieved. Eucommia bark leaf dry powder in the traditional Chinese medicine ingredients contains chlorogenic acid, eucommia polysaccharide, eucommia flavone and the like and can replace antibiotics to enhance the disease resistance immunity of fish and reduce the death rate in the culturing cycle; vitamin C and taurine are added to the feed additive and can promote growth and development of fish immune organs and improve the disease resistance and the culturing water quality; and chitosan can improve the micro-ecological environment of the fish intestinal tract and improve the digestive absorption capability of fish.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a preparation process of a grass carp feed additive containing eucommia powder. Background technique [0002] Grass carp is one of the four major domestic fishes in my country, and it is also the main freshwater fish species in my country. It is very popular among consumers for its tender meat, large body and few spines between muscles. However, in the grass carp breeding process, its disease resistance is poor, the survival rate is low, and it is vulnerable to red skin disease, gill rot disease, enteritis disease and hemorrhagic disease during the breeding process. These four diseases are called "grass carp". Four diseases", the outbreak of these diseases will bring a devastating blow to the grass carp farming industry, so the large-scale farming of grass carp has been greatly restricted.

However, in the grass carp breeding process, its disease resistance is poor, the survival rate is low, and it is vulnerable to red skin disease, gill rot disease, enteritis disease and hemorrhagic disease during the breeding process. These four diseases are called "grass carp". Four diseases", the outbreak of these diseases will bring a devastating blow to the grass carp farming industry, so the large-scale farming of grass carp is greatly restricted

Long-term practice has shown that injecting antibiotics into grass carp can prevent the "four diseases of grass carp"; however, these antibiotics will enter the human body along with people eating various fish products, which indirectly leads to the abuse of antibiotics and may cause a variety of drug-induced diseases. There may even be multidrug-resistant "superbugs"
