Cow Gestation Calculator

The cow gestation is calculated using the following formula:

\[ \text{Calving start} = \text{Day when exposed to bull} + 283 \text{ days} \]

Remember that the healthy gestation period may range from 279 to 287 days.

The end of the postpartum interval period is calculated as follows:

\[ \text{End of interval period} = \text{Calving} + 55 \text{ days} \]

For cows pregnant with their first calf:

\[ \text{End of interval period} = \text{Calving} + 65 \text{ days} \]
