Compound feed for preventing and treating three diseases of grass carp

Abstract

The invention provides a compound feed for preventing and treating three diseases of grass carp. The compound feed is prepared from the following raw materials in percentage by weight: 1%-6% of fish meal, 1%-6% of pork powder, 15%-30% of bean pulp, 15%-35% of rapeseed meal, 1%-10% of cottonseed meal, 2%-13% of DDGS, 0-10% of rice bran, 12%-25% of wheat, 0.2%-0.5% of choline chloride,1.5%-2.5% of calcium dihydrogen phosphate, 1%-1.5% of multivitamin multi-mineral premix, 0.1%-0.3% of a mildew preventive, 0.05%-0.2% of 1-glycerol monobutyralte and 1%-5% of a traditional Chinese medicine compound. According to the compound feed provided by the invention, an experiment proves that the immunity and the anti-pathogenic microorganism capability of the grass carp can be improved; the liver function of the grass carp is improved; and the occurrence probability of three diseases of the grass carp is effectively prevented.

Description

technical field [0001] The invention belongs to the field of aquatic feed, in particular to a compound feed for preventing and treating the three diseases of grass carp. Background technique [0002] Grass carp is one of the most important freshwater economically farmed fishes in my country. With the promotion of intensive farming mode and the continuous improvement of feed technology, it has developed rapidly, with an annual output of more than 4 million tons. However, due to problems such as high-density breeding, water pollution, and degradation of grass carp fry, the survival rate of the culture is low, especially in the "wheat yellow" from April to June and the "white dew tip" from September to October every year. Grass carp fry are vulnerable to Bacterial enteritis, gill rot and hemorrhagic disease (commonly known as the "three diseases" of grass carp), the mortality rate is usually 20-50%, even as high as 70%, causing huge economic losses to farmers and affecting the ...

AI Technical Summary

Problems solved by technology

At present, the prevention and treatment of the "three diseases" mainly adopts the method of feeding antibiotics mixed with feed, but the diseased fish basically stop eating, and the remaining live fish after taking antibiotics will cause serious damage to the liver and affect the later growth. Environmental pollution and drug residues cause serious harm to the human body, and it is easy to cause the pathogens of the disease to develop drug resistance, making it difficult to achieve the ideal curative effect and other vicious circles
