Are the Bulls Ready for the Fall Breeding Season? The fall breeding season is less than a month away. If you have not assessed your bull battery recently, time is running out. Contact your local large animal veterinarian and make arrangements to see that your bulls of all ages pass a breeding soundness exam. In addition, ask your veterinarian about the need for a trichomoniasis test. If the bulls’ feet need to be trimmed, this would be an excellent opportunity to get that done as well.
