Due dates, heat cycles and breeding efficiency — free calculators that keep your herd calving on time.
Calculate the calving due date for a cow (cattle) from the breeding date (gestation ~283 days), with pre-calving management reminders.
Calculate the calving due date for a buffalo from the breeding date (gestation ~310 days), with pre-calving management reminders.
Predict the next heat dates and best AI/service timing for a cow (cattle) from the last observed heat (cycle ~21 days).
Calculate the calving interval in days and months between two calvings and judge reproductive efficiency.
Calculate conception rate from the number of animals confirmed pregnant out of those inseminated.
Project age at first calving from the age at first successful breeding plus gestation, and judge it.
Calculate the kidding due date for a goat (doe) from the breeding date (gestation ~150 days), with pre-kidding management reminders.
