For cow-calf producers that limit the length of the breeding season, the period of rest after removal from females is key for management of herd bulls.  During this time, it is not uncommon for bulls to be observed less frequently and attention to them often falls, albeit unintended, to the bottom of the priority list.  As with females, the time in between breeding seasons represents the opportunity to regain body condition and weight if needed, and this length of rest is certainly reduced when bulls are used in multiple breeding seasons.

It is, however, important to recognize the importance of bull fertility as well, especially in commercial operations that rely heavily on natural service sires.
