How to use the water buffalo gestation calculator
- 1. Choose what you know. Enter the breeding date to get a due date, or switch to the target due date mode to work backwards to the breeding date you need.
- 2. Refine the inputs. Pick the breed so the calculator uses the right average gestation length.
- 3. Plan around the range. Use the earliest and latest dates and the milestone timeline to schedule checks, feed changes and preparation of the calving area.
How long is a water buffalo's gestation period?
The average is 310 days from breeding to calving, about 10 months. Anything between 300 and 320 days is normal, and a typical litter is 1 calf. Treat the calculated date as the middle of that window rather than a fixed appointment.

How breed changes the calving date
Selecting a breed swaps the average the calculator uses, which can move the calving date by more than a week.
| Breed | Average days | Difference |
|---|---|---|
| Average | 310 | — |
| Murrah (river type) | 308 | -2 days |
| Nili-Ravi (river type) | 310 | — |
| Mediterranean (river type) | 310 | — |
| Surti (river type) | 311 | +1 days |
| Jaffarabadi (river type) | 315 | +5 days |
| Swamp buffalo | 330 | +20 days |
Working backwards from a target calving date
If you want calfs on the ground in a particular week, switch the calculator to target date mode and enter the date you are aiming for. It subtracts 310 days to give the breeding date to book, plus the earliest and latest service dates that still land inside your window.
