Warmth and ventilation of piggery in winter

In winter, the enclosure needs to be warmed up and kept warm. Being in a relatively closed environment will greatly increase the indoor carbon monoxide, carbon dioxide and respirable particulate matter content. These harmful substances can cause irritant damage to the respiratory system of pigs and decrease immunity, increase the chance of respiratory diseases, and also aggravate existing disease symptoms. In addition, the air in the winter house is too dry, and the probability of bacteria and viruses floating in the air adsorbing on the body is greatly increased, which is easy to cause a large number of microorganisms and bacteria to multiply, thus causing pigs to suffer from a variety of diseases. Therefore, timely ventilation and disinfection of the house is very important. The ventilation and disinfection methods of winter houses mainly include the following points: 1 Timely ventilation. At noon when the temperature is relatively high, open a small gap in the window to ventilate for one hour. According to the investigation, in the indoor air circulation, the virus bacteria droplets in the air can float for more than 30 hours. If the doors and windows are always open for ventilation, the dirty air can float away at any time, and the indoor also gets sufficient light, and a variety of viruses and germs are difficult to breed and reproduce. 2 Periodically disinfect. Periodically disinfect the house to keep the pigs healthy. Disinfectant drugs should be used in rotation, and the dosage should be determined according to the instructions. Do not increase the dosage without authorization. Before disinfection must be thoroughly cleaned, disinfection should make the ground like a layer of drizzle, not too wet (pigs easy to diarrhea) can not be too dry (do not play the role of disinfection), every corner should be disinfected to. When disinfecting, let the nozzle fall slowly above the pig, do not disinfect the pig. 3 Prevention of ice. Disinfection outside the barn in winter is difficult, especially in the disinfection tanks set up at the entrance to the yard and pigsty. Ice may occur in winter. In this case, sprinkle some salt in the disinfectant so that it does not freeze. Also pay attention to changing the disinfectant in the disinfection pool frequently to prevent the expired efficacy from decreasing or becoming invalid. -------------------------------------- Learning, winter ventilation and insulation is the key!
