| Animal | Average gestation | Normal range |
|---|---|---|

Heifers, twins and male calves tend to come a few days early; a long gestation can mean a large calf. Treat the date as the middle of a window, not a fixed day.
If she strains for more than an hour without progress, or you see only a head or only one leg, call a vet at once.
On average 283 days, about 9 months and 10 days. Anything from 274 to 291 days is normal.
About 310 days, a little over 10 months. A week or two either side is normal.
A vet can confirm pregnancy by rectal examination from about 60 days after AI (earlier with ultrasound). Also watch for heat 18–24 days after AI.
About 60 days before the expected calving date.
60 to 90 days after calving, so she gives one calf every year.
