Abstract

The purpose of this study was to compare how sires rank on EPD generated solely from yearling Angus bull measures against those generated solely from developing heifer measures. Ultrasound EPD from heifer progeny ultrasound measures are ranking the sires identically to the EPD from the bull progeny ultrasound measures. The heifer data complement the bull data, and breeders should be encouraged to scan all of their developing females at or around 390 days of age to improve the accuracy of carcass EPD based ultrasound measures.
