From: | To: |
The Equine Gestation Calculator estimates the foaling date based on the average gestation period of horses (340 days). This helps breeders and owners prepare for the arrival of the foal.
The calculator uses the standard equine gestation formula:
Where:
Note: Actual gestation can range from 320-370 days, with 340 days being the average.
Details: Knowing the expected foaling date helps in proper mare care, scheduling veterinary checks, and preparing foaling facilities.
Tips: Enter the exact breeding date for most accurate results. Remember this is an estimate - mares may foal earlier or later than the calculated date.
Q1: How accurate is the 340-day estimate?
A: While 340 days is the average, normal gestation can range from 320-370 days. First-time mares often carry longer.
Q2: What factors affect gestation length?
A: Breed, season, mare's age, foal's sex, and nutrition can all influence gestation length.
Q3: When should I start monitoring the mare closely?
A: Begin close monitoring about 2 weeks before the calculated due date.
Q4: Can the due date be predicted more precisely?
A: Veterinary exams including ultrasound and progesterone testing can help narrow the window.
Q5: What if my mare goes significantly past the due date?
A: Consult your veterinarian if gestation exceeds 365 days as this may indicate problems.
