Abstract
Regularly reproducing dairy cows are critical to the success of every dairyman. The most effective measure of reproductive efficiency for a herd is average days open, the number of days between the most recent dates of calving and breeding. This guideline will help you evaluate the success of your heat detection program, an important influence of days open.
