Bedding management is the single most critical factor in deep bed swine production, it effects animal performance, animal behavior, animal health and the quality of the building environment. The two categories of deep bed systems currently utilized in the US swine industry are the sand based and carbon based systems. The sand-based system relies on removal of the liquid through evaporation into the atmosphere. This lowers the temperature within the building, therefore providing the animal a cooler environment. The carbon system is based on providing a bedding pack with a proper C/N ratio and physical structure to provide the optimal animal environment by absorption, evaporation, and composting. There are currently two bedding management approaches within the category of carbon based bedding systems, the single addition and the continuos addition approaches. The selection of bedding materials determines the level of animal comfort, nitrogen stabilization and composting, therefore there are a minimum of ten basic factors which must be considered before selection and utilization of a bedding material.
