Livestock Gestation Calculator
How It Works
Select Your Livestock Type – Choose cattle, sheep, goats, pigs, horses, or other.
Enter Breeding Date – Input the date of exposure or insemination.
See the Result – The calculator uses species-specific average gestation periods to give you an estimated due date instantly.
Most livestock—like cattle and horses—have gestations around 283–292 days, while sheep (~150 days), goats (~150 days), pigs (~114 days), and horses (~340 days) differ slightly. Our calculator uses the most up-to-date averages for each species for optimal accuracy.
Why Use This Calculator?
Stay Prepared – Plan housing, vet care, and feed well in advance.
Reduce Stress – Prevent surprises and ensure smooth birthing seasons.
Improve Herd Health – Keep closer watch over animals nearing their due dates.
