Where:
DD = Due Date
BD = Breeding Date
| From: | To: |
The horse due date calculation estimates the foaling date based on the breeding date. The average gestation period for horses is approximately 340 days, though it can vary from 320 to 370 days.
The calculator uses the standard horse gestation formula:
Where:
Explanation: This calculation adds 340 days (average gestation period) to the breeding date to estimate the foaling date.
Details: Accurate due date estimation is crucial for proper mare care, scheduling veterinary checks, and preparing for foaling.
Tips: Enter the breeding date in the format YYYY-MM-DD. The calculator will add 340 days to estimate the foaling date.
Q1: Is 340 days the exact gestation period for all horses?
A: No, it's an average. Gestation can range from 320 to 370 days depending on breed, season, and individual factors.
Q2: What factors can affect the gestation period?
A: Mare's age, nutrition, season (longer in winter), foal's sex (colts often longer), and breed variations.
Q3: When should I start monitoring the mare closely?
A: Begin close monitoring about 2-4 weeks before the calculated due date as foaling can occur earlier.
Q4: Are there signs that foaling is imminent?
A: Yes, including udder development, vulva relaxation, waxing of teats, and behavioral changes.
Q5: Should I rely solely on this calculator?
A: No, use this as a guide along with veterinary advice and observation of the mare's condition.
