Horse Gestation Period:
| From: | To: |
The average gestation period for horses is approximately 340 days (about 11 months), though it can range from 320 to 370 days depending on various factors including breed, season, and individual mare characteristics.
The calculator uses the standard gestation period:
Calculation: The calculator adds 340 days to the breeding date to estimate the foaling date.
Details: Accurate gestation tracking helps prepare for foaling, schedule veterinary checks, and monitor the mare's health throughout pregnancy.
Tips: Enter the breeding date to calculate the expected foaling date. The calculator will also show how many days remain until foaling or if the mare is overdue.
Q1: Is 340 days exact for all horses?
A: No, it's an average. Some mares foal earlier (as early as 320 days) while others may go longer (up to 370 days).
Q2: What factors affect gestation length?
A: Breed, season (mares bred in spring tend to have shorter gestations), foal gender (colts often have longer gestations), and mare age.
Q3: When should I start watching for foaling signs?
A: Begin close monitoring at 320 days, with increased vigilance after 330 days.
Q4: What if my mare goes past 340 days?
A: While concerning, some normal pregnancies last up to 370 days. Consult your veterinarian if gestation exceeds 350 days.
Q5: Can this calculator predict exact foaling date?
A: It provides an estimate based on averages. Individual variation means the actual foaling date may differ.
