How should winter pig house insulation and ventilation be done?

In winter, the pen needs to be heated and kept warm while being in a relatively enclosed environment, which greatly increases the indoor levels of carbon monoxide, carbon dioxide and inhalable particulate matter. These harmful substances can cause irritating damage to the pig's respiratory system and lower immunity, increase the chance of respiratory diseases, and also aggravate the symptoms of existing diseases. In addition, when the air in the house is too dry in winter, the probability that bacteria and viruses floating in the air will attach to the body is also greatly increased, making it easy for microorganisms and pathogens to multiply in large numbers, thus causing pigs to suffer from a variety of diseases, so timely ventilation and disinfection of the pen are very important. The main methods of ventilation and disinfection of the pen in winter are as follows: 1 Timely ventilation. When the temperature is relatively higher at noon, open the window a small crack for one hour of ventilation. According to surveys, in rooms without air circulation, virus and bacteria droplets in the air can float for more than 30 hours. If doors and windows are often opened for air exchange, the stale air can drift away at any time, and the room also gets sufficient light, making it difficult for many kinds of viruses and pathogens to breed and multiply. 2 Regular disinfection. Disinfect the house regularly so that the pigs remain healthy as they grow. Disinfectants should be used in rotation, and the dosage should be determined according to the instructions; do not increase the dose on your own. Before disinfection, be sure to clean thoroughly. During disinfection, make the floor look as if a light drizzle has fallen on it; it should not be too wet (pigs are prone to diarrhea) or too dry (which would fail to disinfect). Every corner must be disinfected. During disinfection, keep the nozzle above the pigs so that the liquid falls slowly; do not spray disinfectant directly at the pigs. 3 Prevent freezing. Outdoor disinfection in winter is very difficult, especially for the disinfection pool set up at the passage entering the farm area and pig house, which may freeze in winter. In this case, some salt can be sprinkled into the disinfectant so that it will not freeze. Also pay attention to frequently changing the disinfectant in the disinfection pool to prevent reduced efficacy or failure after expiration.
