Bull calves should be closely examined for structural and hoof soundness, conformation, ample muscular development, scrotal circumference, disposition, and genetic merit using breed association genetic evaluation tools, such as expected progeny differences (EPDs).Īs bulls mature, their nutritional requirements change.

Performance measurements, such as 205-day adjusted weaning weights, can be used as an evaluation tool to select bulls. Once these specifics have been analyzed and a development strategy outlined, producers can carefully evaluate bull calves at weaning to select the ones to continue developing as potential herd sires. Overall goals for bull development will vary from one operation to another due to differences in management, marketing, and other factors. Necessary factors to consider include accessible acreage, labor, facilities, forages, and capital for bull development within the operation. To best design a bull nutritional development strategy, producers must first evaluate available resources. Beef producers generally market bulls as yearlings (13 to 17 months old) or as 2-year-olds (20 to 24 months).
