Abstract
Central Iowa hoop structures used for finishing pigs were closely monitored. Bedding use was 124 lb to 262 lb per pig for the finishing period. More bedding was used in winter than in summer. The bedding was primarily large round bales of cornstalks. Labor requirements varied from .3 to .6 hours/pig depending on total bedding use and experience of the manager. The bedding/manure pack was sampled at nine locations. Pack temperatures ranged from 30oF to 113oF 6 inches below the surface during February. Moisture content varied from 23 to 75% moisture. Nitrogen (N), phosphorus (P), and potassium (K) values also were variable. Soil samples under the pack indicated increased soil nitrogen as nitrate. More research is needed in all of these areas.
