It is common practice this time of year to evaluate cows to make culling decisions, but this is also a good time to evaluate bulls to determine which sires will be fed through the winter and which have come to the end of their genetic contribution to the operation.
Like cows, bulls can live 10 to 12 years. Most bulls will remain active in the herd for closer to four or five years before they experience feet and leg, structural, and fertility problems; temperament concerns; or injuries.
