At present, many farmers are broilers in 70-90 days old, and after 10 days of castration, they often have more severe respiratory diseases.
Many farmers keep chickens in the mountains. They are separated by a long distance. They think the venues are clean and there are no infectious diseases, especially throats. Therefore, they refused to use throat-transmitting vaccines. There are also some farmers who are already suffering from respiratory diseases, but they also take care of it. In order to prevent the occurrence of the disease, the following suggestions are proposed:
(1) For farmers raising pheasants, whether or not they are first raised, they should be vaccinated with throat-threatening vaccine at 30 to 40 days of age. Inoculation can also be achieved 20 days before pheasants.
(2) For some chickens suffering from respiratory diseases, they should be treated. After the chickens return to health, they must be castrated to avoid causing other diseases.
(3) There are also many factors that can cause the spread of infectious diseases in chickens in the mountains, such as the flow of chicken hawkers between chicken farms.
Therefore, it is recommended that farmers strengthen the disinfection of chicken farms, chicken houses and sports grounds, and prohibit chicken dealers and other people from entering the chicken farm.
