Whether it’s natural or mechanical, barn ventilation is imperative when it comes to the welfare of dairy cattle. However, ventilation alone does not always provide the necessary air movement for cooling and comfort needs, a sensitivity that animals can intrinsically demonstrate simply by their eating habits, conception rates and milk production. Without a cooling breeze, the simple ventilation designed into a building isn’t enough. A properly designed and equipped barn will not only allow an adequate air exchange rate, but will also improve cow comfort.
