This stallion is being led toward a mare standing in the teasing area about 30 feet behind the stallion, out of this view.  A reliable teasing process is critical to detect when a mare is in estrus (heat).  This helps determine the optimal time for breeding to optimize fertility, and minimizes costs associated with trans-rectal palpation of the ovaries or ultra sound to verify ovulation. This stallion is standing quietly, with his ears forward and attentive to the handler despite the mare in close proximity. For the safety of the handlers and horses, the tease stallion must be manageable at all times.  For her own safety, the handler should constantly watch the stallion and the lead rope should not be looped around her hand.
