Where:

• Breeding Date — The date when the cow was bred
• 283 days — Average gestation period for Black Angus cattle

Note: Actual gestation can vary by ±10 days depending on individual factors.

3. Importance of Accurate Gestation Calculation

Details: Knowing the expected due date helps with proper herd management, nutritional planning, and preparation for calving.

4. Using the Calculator
