The recent heavy rains in East China and South China and the middle and lower reaches of the Yangtze River have caused floods of varying degrees. The number of people affected in Anhui Province alone has exceeded 420,000, the area of crops affected has exceeded 20,000 hectares, and more than 600 houses have collapsed.
According to the forecast by the Meteorological Observatory, heavy rainfall in the southern part of the Jianghuai and southern Yangtze River areas will continue for some time.
After the flood, prevent a major epidemic
The epidemic prevention work after the flood cannot be ignored.
In addition to the epidemic protection of the crowd, don't forget pets and domestic animals.
After the floods, various pathogens such as bacteria, viruses, fungi, and parasites in forests, soils, and swamps were washed away by the floods. Together with blood-sucking insect activities and the sultry and humid climate, animal diseases are very likely to occur and spread. After the floods, animals are susceptible to gastrointestinal and parasitic diseases.
Among them, the most notable infectious diseases and parasitic diseases are coccidiosis, brucellosis of cattle and sheep, schistosomiasis bovine, leptospirosis, streptococcal disease and so on. Coccidia oocysts can develop into infectious oocysts within 2 to 3 days in an external environment with a temperature of 20°C and a humidity of 55% to 75%.
Today we talk about a monensin, a feed additive used to prevent epidemic coccidiosis.
Monensin
CAS number: 17090-79-8
Monensin is a polyether ionophore antibiotic. It is a feed additive widely used in ruminants. It is mainly used to prevent coccidiosis and promote the growth of ruminants. It is also effective for Gram-positive bacteria (especially golden yellow) Staphylococcus, Streptococcus, Bacillus subtilis) and Treponema pallidum have a strong effect. Monensin can affect the chemical ion balance in bacteria, causing the worm to rupture and die.
In high-concentration fattening, the application of monensin can promote the production of propionic acid in the stomach, reduce the loss of protein in the feed during digestion, and make the intestinal wall thinner to facilitate the penetration and absorption of nutrients. Monensin can also promote the pituitary gland to secrete hormones to promote growth and development.
In addition, monensin can hardly be absorbed in the digestive tract, so there is generally no problem of residue in edible tissues, which belongs to a safer feed additive.
