Chicken and duck miscellaneous damage
As the Spring Festival approached, the sales of chickens, ducks and other poultry on the market continued to rise. However, we often see in the market that some poultry sales vendors sell chickens and ducks in a single vehicle, transport them together, and spend the night together. This is an act that does not meet the requirements of hygiene and epidemic prevention. Not only chickens and ducks cannot be mixed during transportation, but also the polyculture of poultry is a very unscientific breeding method. Many farmers are now busy killing chickens and slaughtering ducks. They are busy with slaughter and replenishment of poultry and ignore the epidemic prevention. Although the current bird flu epidemic has been effectively controlled, it is during the Spring Festival that the bird flu epidemic is likely to occur. Some spring ducks have bacteria or viruses that are not sensitive to chickens and are sensitive to them. If the duck is infected with the chicken Newcastle disease virus, the duck itself is not easy to attack, but it is easy to make the chicken dead. There are more Pasteurella in the duck than in chickens, which can cause chicken cholera. When the ducks are exposed to water, they can easily wet the poultry house and cause the disease to multiply, causing the poultry to become ill. In addition, the living habits of chickens and ducks vary greatly, and polycultures will interfere with one another and be detrimental to growth. Cold weather in winter and spring, chickens and ducks are often together in the nest, long time and easy to cross infection. Therefore, poultry farmers must not take any precautions against the bird flu epidemic. The epidemic prevention must not be relaxed and cannot be ignored.
