MATING ABILITY

Mating ability is the ability of the bull to complete the mounting and insemination successfully.

• Mating ability may be impaired due to deviations and loss of innervations of the penis, problems of musculoskeletal system, especially unsoundness of the rear legs and lower back.
• Observation of the bull as he walks may be helpful to diagnose the inability to mate due to arthritis, injuries or other lameness.
• All bulls should be turned with estrus females and be observed by the veterinarian or owner to detect deficiencies in libido or mating ability.
• Ventral and lateral deviations, the corkscrew configuration, persistent frenulum and injuries of the penis can all be observed in affected bulls during attempts at natural service.
