Buffalo pregnancy guide
How long is a buffalo pregnant?
A buffalo is pregnant for about 310 days (about 10.2 months). The normal range is 300 to 320 days, so most calf arrive within that window rather than on the exact average day. Breed shifts the date by a few days, which is why the calculator asks for it.
Quick rule: Count about 10 months forward from the breeding or ai date, then adjust for breed.
How to use the buffalo pregnancy calculator
1. Enter the breeding or ai date. The day of artificial insemination or natural service. Tap Use today if it was today.
2. Pick the breed. The whole window moves with the breed average.
Then follow the schedule. Each task gets a real date, the next one is highlighted, the status shows whether your buffalo is on track, and the month by month cards above show where things stand. Use Copy schedule or Add to Google Calendar to keep it.
Gestation formulas
- Estimated calving date = breeding or ai date + 310 days
- Earliest normal calving = breeding or ai date + 300 days
- Latest normal calving = breeding or ai date + 320 days
- Breed adjustment = breed average minus 310 days, applied to the whole window
- Call your vet if nothing has happened by day 325
