A tool used to estimate the delivery date of a pregnant mare relies on the date of the last known breeding or cover. Typically, these tools add 340 days (approximately 11 months) to the breeding date to arrive at an estimated due date. Variations exist that allow for adjustments based on factors such as breed and individual mare history.
Predicting delivery dates in equine breeding is crucial for optimal management of the mare and preparation for the foal’s arrival. Accurate estimations allow breeders to schedule necessary veterinary check-ups, prepare appropriate foaling facilities, and ensure the availability of experienced personnel during the birthing process. Historically, breeders relied on less precise methods for estimating foaling dates. Modern tools offer increased accuracy, leading to improved outcomes for both mare and foal.
