Reasons for the high incidence of ASF in winter
1. The disease resistance of pigs is the worst in winter, and various diseases of pigs are the highest incidence period in winter.
2. In northern winter pig houses, ventilation and warmth cannot be taken into account at the same time. After the heating is ensured, the air in the pig house is not circulated, which is easy to be infected with viruses; after the ventilation is ensured, the temperature in the pig house drops, and the pigs are easy to catch a cold.
3. Freezing makes the sterilizing water unable to work.
4. Rain and snow mud greatly reduces the decontamination effect.
Since December 2018, the number of live pigs has dropped significantly month-on-month.
