Abstract

The goal of this brief review is to evaluate whether reproductive programs for lactating dairy cows may be solely dependent on timed AI protocols or AI on detected estrus. A few examples of dairies that have attempted to eliminate one or the other will be given, but I caution that some of these examples are merely data extracted from on farm software and not the result of controlled studies.
