It also removes dirty air and replaces fresh air, which is beneficial to pig growth and development. However, the winter and spring temperatures are low and the ventilation volume must be controlled. The wind speed in the house should not exceed 0.1-0.2 meters per second. Increase the temperature before ventilating. Change grass bedding. The mat grass has strong water absorption and easily absorbs the moisture of the excreta or is easily polluted by the excrement.
