Abstract

Physical and chemical body composition of gilts and parity 3 sows were used to determine current prediction equation accuracy and propose alternative prediction equations that incorporate additional variables. Longissimus dorsi muscle depth and parity can be combined with body weight and backfat to improve gilt and sow body composition prediction.
