Kansas Agricultural Experiment Station Research Reports
Data on Charolais-sired calves were analyzed to evaluate progeny performance related to sire expected progeny differences (EPD) in a large data set of commercial crossbred cattle in several herds across the United States. The traits analyzed were birth weight (n=3,554) and weaning weight (n=3,604) of crossbred progeny from nationally evaluated sires. Birth weight EPD and weaning weight EPD were evaluated as predictors of crossbred performance. Random regression coefficients were estimated for progeny birth weight on sire birth weight EPD of 1.03±0.09 lb/lb of birth weight EPD, and for progeny weaning weight, 0.66±0.11 lb/lb of weaning weight EPD.
