1. What is Cow Gestation Period?

The average gestation period for cows is 283 days (about 9 months and 2 weeks), though it can vary by breed from 279 to 287 days. This calculator uses the standard 283-day average for estimation.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Breeding Date — Date when cow was bred or artificially inseminated
• 283 days — Average gestation period for cattle

Note: Actual calving may occur 7-10 days before or after the calculated date.

3. Importance of Accurate Due Date

Details: Knowing the expected calving date helps with proper nutrition management, preparation of calving facilities, and scheduling veterinary checks.

4. Using the Calculator

Tips: Enter the exact breeding date if known, or your best estimate. The calculator will add 283 days to determine the approximate due date.

5. Frequently Asked Questions (FAQ)
