My Angus bulls' weaning and yearling weights are comparable or better than the crossbred calves running through my local sale barns..
Most of the cattle at the stockyard are grade cows crossed to grade bulls usually of different breeds. A breeder who uses performance Herefords x performance Angus x performance Charolais is going to wean HEAVIER calves than the guy who breeds mediocre Herefords x mediocre Angus x mediocre Charolais (for just one crossbreeding example). Both breeders are getting heterosis and are weaning more pounds of calves than if they were straight breeding; but there are purebred Hereford herds which are weaning a 620+ pound calf crop, dittoe with Charolais and Anguses. While those cattle would have better perfromance by crossbreeding, those pure performance lines surpass the performance of average grade crossbred cattle. Also a lot of heterosis effects are not visible at the stockyard. Increased female fertility and longevity and calf survival rates translates into dollars on the farm; but aren't measured by a scale.
