Drug for preventing and treating picornvirus disease and preparation method thereof

Abstract

The invention discloses a drug for preventing and treating picornvirus disease and a preparation method thereof, relating to the technical fields of the prevention and treatment of river crab diseases. The drug contains the following components in parts by weight: 20-30 parts of radix isatidis, 15-25 parts of liquorice, 15-25 parts of folium mori, 15-25 parts of rhizoma coptidis, 10-20 parts of cortex cinnamomi, 10-20 parts of rhizoma curcumae longae, 10-20 parts of pericarpium granati and 15-25 parts of herba moslae. By adding the drug into feeds or directly scattering the drug into a water body, pathogens lurking in crab bodies, water bodies and sludge can be well killed, so that the picornvirus disease can be well prevented and inhibited; and the preparation method of the drug is simple. Besides, the drug further contains rich beneficial nutrients such as amino acids and vitamins, so that the immunity and disease resistance of the crabs can be enhanced, the crabs can be adaptive tothe change of a water body environment, and the growth of the crabs can be promoted.

Description

technical field [0001] The invention relates to the technical field of river crab disease prevention and control, in particular to a medicine for preventing and treating river crab shivering disease and a preparation method thereof. Background technique [0002] Crab shivering disease is the most harmful crab disease to the crab breeding industry, and it is the most important thing in the prevention and treatment of crab diseases. Tremor disease is also known as tremor disease, ring leg disease and so on. The crab germplasm is mixed or inbreeding, the stocking density is too high, the size is not uniform, and the crab nutrient intake is unbalanced, etc., which are prone to this disease. In the early stage of the disease, the limbs of the sick crab can still be straightened, and then the muscles will atrophy, and the legs cannot be stretched back. After shelling, water will accumulate in the body, and it will die after 3 to 4 days. The disease mainly harms 2-year-old juven...

AI Technical Summary

Problems solved by technology

[0003] The prevention and control of river crab shivering disease requires thorough disinfection of the breeding ponds and splashing with bleaching powder and quicklime. It is also necessary to add antibiotics such as oxytetracycline or chloramphenicol to the feed or directly spray them for treatment. However, antibiotics are not used properly. It will cause bacteria to develop drug resistance, but reduce the body's immunity, affect the safety and quality of crab meat, and cause certain safety hazards for people to eat
