1. What is Horse Gestation?

Horse gestation refers to the period between conception and birth in mares. The average gestation period is about 340 days, but can vary based on the mare's age, breed, and other factors.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• 340 days — Base gestation period
• Age adjustment — +10 days for mares under 5 years, +15 days for mares over 20 years

Explanation: Younger and older mares typically have slightly longer gestation periods than mares in their prime breeding years (5-20 years old).

3. Importance of Gestation Calculation

Details: Accurate gestation calculation helps in proper foaling management, ensuring the mare receives appropriate care and nutrition during pregnancy, and preparing for the foaling process.

4. Using the Calculator

Tips: Enter the mare's age in years (must be between 2 and 30). The calculator will provide an estimated gestation period in days.

5. Frequently Asked Questions (FAQ)

Q1: What's the normal range for horse gestation?
A: While the average is 340 days, normal gestation can range from 320 to 370 days.

Q2: Does breed affect gestation length?
A: Yes, pony breeds often have shorter gestation (320-340 days) while draft breeds may have longer gestation (up to 370 days).

Q3: What factors besides age affect gestation?
A: Season (mares bred early in the year often carry longer), sex of foal (colts may be carried longer), and nutrition.

Q4: When should I start monitoring for foaling?
A: Begin close monitoring about 30 days before the expected due date.

Q5: What if my mare goes significantly past her due date?
A: Consult your veterinarian as gestation beyond 365 days may indicate problems.
