what happens a mare that is bred but does not conceive
If the mare does not conceive, she will return to estrus (heat) in approximately 15 days from the last heat shown. If the mare does not return to estrus 18 to 20 days after breeding, a competent palpator or ultrasound exam will provide an indication of whether the mare has conceived. Teasing should still continue. Do not force a stallion to breed a mare to which he has considerable objection. 2  Do not use the stallion excessively as a teaser. 3  The most common practice on large breeding farms is to have a stallion that is used solely as a teasing horse.
