Large hog farms often utilize several separate buildings primarily to manage disease risks and to accommodate the specific needs of different animal groups.1
By housing animals in separate structures, producers can effectively isolate different stages of the life cycle—such as suckling sows, in-pig sows, fattening pigs, and boars—which helps maintain herd health and operational efficiency. This physical separation is a key component of biosecurity, as it limits the transmission of infectious diseases between groups of pigs that may have varying levels of immunity or age-related health requirements.123
