Abstract: This paper briefly introduced the characteristics of hoop structure. The performance of pigs raised, animal hygiene, and environment quality inside hoop structures were compared with their counterparts in the confined animal houses. Bedding management was also included. The analysis gets the results as following. Compaired with the pigs in confined animal house, the pigs in hoop structure are little worse in some producing index. They can basically meet the demond of production. The hoop structure can both save water resources and reduce environmental pollution. It is benefit for sustainable developing of pig (industrilization) huslandry.
