beef cattle, commercial, expected progeny difference, corssbred offspring
Actual performance of crossbred calves produced at the Antelope Range Livestock Station was evaluated and compared to the sire's expected progeny differences (EPDs) as reported in 1988 beef breed association sire summaries. Comparisons were made between high EPD and low EPD sire groups in retrospect for actual birth weight and weaning weight performance of crossbred progeny. Separate analyses were completed for Polled Hereford, Simmental, Tarentaise and Angus sires. Progeny of high EPD sires ranked higher for average birth weight than progeny of low EPD sires for all sire breeds. Rankings for calf weaning weight were less consistent than for birth weight in reflecting rankings of sire EPDs.
