To control the propagation, growth and spread of pathogenic microorganisms means not to provide them with a place to live and a way to spread. That is to say, the pig farm cooperates with the pig breeding equipment to provide a good environment and effective disinfection measures for the pig population, so as to reduce the number of pathogenic microorganisms in the pig growth environment and provide a good living environment for the pig population. This requires strict requirements for the health management of the pig population. Here is a brief introduction.
1. Clean the enclosure in time every day, clean up the production waste, keep the inside and outside of the house clean and tidy, and put the articles in order.
2. Keep the house dry and clean. Clean the pig manure in the pen every day. Try to separate the pig and the manure. If the pig house is dry, clean the pig manure in the morning and afternoon in time and pile it up in the designated place. If the pig house is washed with water, clean the pig manure in the ditch in time and wash it away with clear water in the afternoon to keep the pig body and the pen clean.
3. Transfer a batch of pigs every week, clean and disinfect after the empty circle, put the pigs to bed or adjust the circle, wash the empty circle first and then disinfect it with broad-spectrum disinfectant, clean and wash the empty circle first and then disinfect it with disinfectant after each batch of weaning, fattening and fattening in the delivery room.
4. Pay attention to ventilation. Keep warm in winter and keep the air in the house in good condition. In winter, ventilate with fan for 5-10 minutes (each section is ventilated according to the specific situation). Summer ventilation heatstroke prevention, exhaust harmful gases.

After each empty house, it shall be cleaned thoroughly, but not every month or every quarter. Clean the outside environment once a month.
