| Summary: | ︢1.2 cm2), YG (2.98 .︢08), and QG (672 ︢5). The steers ︢3 kg), FT (I. 10 ︢.05 cm), KPH (I. 91 + .09 %), REA (80.2 (FW), carcass weight (CW), fat thickness (FT), kidney, (IW), grass ADG (GADG), feedlot ADG (FADG), final weight (YG), marbling score (MS), quality grade (QG), and shear 56 purebred Beefinaster steers, representing I I purebred and 168-d. A fixed effects model was used with sire and kill Beefinaster sires were used in a cooperative study sponsored by Beefmaster Breeders United. The steers were grazed on carcass ribeye area was 0.59. correlation between ultrasound ribeye area and observed differences were observed in IW (P < .05) and GADG (P <.001). FW (P <.Ol), CW (P <,05), FT (P <.05), and SF (P <.05). There GADG (0.71 .︢03 kg), FADG (1.58 .︢02 kg), and FW (534 ︢5 group as independent variables to analyze initial weight kg). The steers met industry-acceptable ranges for CW (3 3 5 mean shear force of 2.74 .︢07 k-a 0. Kill group effect was pelvic, and heart fat (KPH), ribeye area (REA), yield grade Postweaning growth, carcass yield, and lean quality traits of real-time ultrasound measures of fat thickness and live significant for IW (P <.05), GADG (P <.001), FADG (P < .001), Sire effects were not found for FADG, FW, CW, FT, KPH, REA, Texas A&M Agricultural Research Center, McGregor, TX. Using thickness and observed carcass fat thickness was 0.69. The values in previously published research for IW (269 ︢4 kg), was no kill group effect for KPH, REA, YG, MS, or QG. Sire weight, the steers were sorted into 3 kill groups: 112, 140, were clearly acceptable in Wamer-Bratzler tenderness, with a wheat pasture for 69 days, then finished in drylot at the YG, MS, QG, or SF.
