Special feed additive for grass carp

Abstract

The invention relates to a special feed additive for grass carp. The special feed additive is characterized by comprising the following components in mass percent: 15-20% of rhizoma coptidis, 10-12% of dandelion, 10-15% of endive, 10-15% of caulis lonicerae, 10-15% of Astragalus mongholicus, 8-12% of Angelica sinensis, 5-8% of fructus forsythia, 5-9% of glossy privet fruit and 10-30% of pine needle meal. About 0.8-2% of the feed additive for grass carp is added in grass carp compound feed, the four diseases of the grass carp can be effectively prevented, then the survival rate of the grass carp culture is effectively improved, the growth of the grass carp is promoted and the economic benefit of the culture is improved.

Description

technical field [0001] The invention relates to a feed additive for aquaculture, in particular to a special feed additive for grass carp capable of promoting the growth of grass carp and improving the immunity of grass carp. 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 China. 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. Long-term practice has shown that injecting ant...

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"
