This is unfortunately the way a problem is usually discovered in stallions who breed by live cover as their semen is routinely not examined at each breeding. Some farms overcome this problem of live cover by retrieving a small dismount semen sample and routinely examining it for motility and concentration .The breeding soundness exam will allow you to decide on a reasonable book for the season. If low sperm numbers, concentration, or motility are discovered, mare and stallion management can be adjusted for better results. The individual s sperm can be evaluated for its ability to be chilled and shipped and how many inseminations may be expected from each semen collection. Thoroughly dry the stallion with a clean towel.
Some stallions become distracted or less interested in breeding as the season progresses.
There are many techniques you can use to stimulate his desire to breed mares. Teasing him to either his favorite mare works for some, other stallions require different mares, while other stallions respond to teasing for longer intervals. Some stallions are extremely aroused by mares being led away while others prefer to see them led towards them. Managing a stallion is usually not a difficult job. It requires very careful observation and attention to the stallion and a fair amount of patience and caution.
