110th rib backfat, last rib backfat, and longissimus muscle area at 10, 13, 16, 19, and 22 wk of age estimated using B-mode ultrasound (Pie Medical 200SLC, Classic Medical Supply Inc., Tequesta, FL).

2Age at 105 kg calculated following National Swine Improvement Federation guidelines [40].

3Total body fat tissue, fat-free total lean tissue, empty body protein, and empty body lipid at 22 wk of age calculated by using equations similar to those used by Wagner et al. [41].
