A small demonstration sow herd has been housed during breeding and gestation in a deep-bedded hoop structure. Conception rates, number of pigs born alive, and birth weights were excellent. These results indicate that hoops provide a realistic alternative for housing gestating sows. A discussion of the decision considerations related to animal environment, sow behavior, bedding and manure, and feeding systems is included. Seven distinct floor plans are included. Hoop structures are a new, viable alternative housing system for gestating sows.
