Abstract
The genetic traits of a purebred bull convey the reproductive and economic value to buyers.
This study examines and compares the value of actual production weights (birth, weaning,
and yearling weight), production expected progeny differences (EPDs) (birth, weaning,
milk, and yearling), and ultrasound EPDs (carcass quality predictors) for purebred Angus
bulls sold at auction. One EPD, birth weight, was valued by buyers more than its
corresponding actual weight, though both actual weights and EPDs significantly impact
price. Predictors of carcass quality were important in determining price. Finally, several
individual animal factors and sale characteristics were significant in determining price.
