Abstract

Real-time ultrasound (RTU) images from replacement Angus heifers were analyzed to determine adjustment factors and genetic parameter estimates. The traits analyzed included ribeye area, 12-13th rib fat thickness, rump fat thickness, and % intramuscular fat. Adjustments were calculated for heifers averaging 805 lbs at time of scanning. The adjustments include age adjustment and weight per day of age adjustment factors.
