Identifying the time of ovulation is crucial for efficient breeding. Most breedings will result in conception when they occur 24 to 36 hours before ovulation or the day of ovulation. Here are some tools you can use to approximate the right time.
  • Teasing
  • Palpation
  • Ultrasound
  • Artificial lighting

Your best resource for breeding management is your veterinarian. He or she can accurately predict ovulation and help you more efficiently manage your breeding program. The use of Regu-Mate® (altrenogest) to suppress estrus in order to facilitate scheduled breeding requires a veterinarian's prescription and consultation - steps to ensure you get your mare bred on the timeline you want with the results you're after. Ask your veterinarian to put together a breeding plan customized for your operation or use our Interactive Calendar.

Put your mare's cycle on your schedule.
The synthetic form of progesterone, progestins have several applications in a breeding program:
  • Suppress estrus in mares.
  • Facilitate attainment of regular cycles in the transitional mare.
  • Facilitate management of the mare exhibiting prolonged estrus.
  • Facilitate scheduled breeding.
Oral progestin hormone, Regu-Mate®, effectively suppresses estrus during the time it's administered. When treatment is discontinued, mares come in estrus within 4 to 5 days and ovulate within 5 to 7 days following the onset of estrus. Progestin treatment can be started at any point in a mare's cycle. The best results are with mares who have follicles 20 mm or greater in diameter and who have been in estrus for 10 or more days.

Talk to your veterinarian about proper use and safe handling of Regu-Mate®. Avoid skin contact. Always wear protective gloves when administering Regu-Mate®. This product is contraindicated for use in mares with a previous or current history of uterine inflammation. Pregnant women, or women who suspect they are pregnant, should not handle this product.
