In the first two, each treatment group of pigs was confined to a 3 ½ by 8-foot concrete-floored pen in the central farrowing unit. In the third experiment 3-by6-foot pens with either flattened expanded metal or wood slat floors were used. A 25-watt light was suspended above the sleeping area in each pen to provide supplementary heat. Wood shavings were used for bedding in the first two experiments, but no bedding was used in the third experiment.SwineFeed additivesGainDaily feed intakeConference paper
