Try your hand at foal-heat breeding.
What’s a good strategy to use to get your mare bred on a foal heat?
Try this commonly used foal-heat breeding strategy:
- Have the mare ultrasounded on days 7 and 9 post foaling.
- Mares ovulating on or before Day 9 are not bred. Instead, they are short-cycled – monitored through ovulation and given prostaglandins (typically five days after ovulation) to bring them back into heat.
- Mares that still have a large follicle nine days post foaling are bred as normal. Use of ovulation-inducing agents (hCG, deslorelin, etc.) is discouraged until days 9 or 10.
