The calendar that works
Dr. Ross has managed mare breeding programs across northeast Oklahoma for 30 years.
- Late November–December: lights on
- Mares are long-day breeders. Sixteen hours of light a day starting around Thanksgiving pulls the first ovulation forward — the standard approach for January and February foals.
- December–January: book the stallion
- Popular stallions’ books close early, and shipped-semen contracts take paperwork. Decide the cross before the season decides for you.
- January: the pre-breeding exam
- Reproductive exam, uterine culture and biopsy where indicated, a Caslick’s check, plus vaccination and dental review. Problems found now are still fixable now.
- February–April: breed on the cycle
- Teasing and ultrasound tracking, insemination timed to ovulation, then pregnancy checks at 14–16 days and again around 28–30 days.
Decisions to make early
- Fresh, cooled or frozen
- Each option changes the calendar and the cost. We work with all three and will tell you honestly which fits your mare and your stallion.
- Embryo transfer & recipients
- For mares who can’t or shouldn’t carry, embryo transfer into a recipient mare keeps the genetics moving. Planning starts before the flush, not after it.
- The Oklahoma Bred angle
- Foals bred and foaled in Oklahoma position for Oklahoma Bred incentives — worth factoring into stallion and foaling decisions from the start.
