Add the breeding date and choose an average gestation length. The calculator will estimate the due date, likely kidding window, and useful management checkpoints during pregnancy.
Formula used:
Estimated due date = breeding date + gestation length
Early kidding date = due date − early offset
Late kidding date = due date + late offset
Milestone dates are calculated by adding selected day counts to the breeding date
Estimated due date = breeding date + gestation length
Early kidding date = due date − early offset
Late kidding date = due date + late offset
Milestone dates are calculated by adding selected day counts to the breeding date
