Timing Milk-based PAG Pregnancy Tests

Identifying open cows in a timely manner is essential for successful reproductive management of the dairy herd.  Fortunately, the options for doing so have been expanding.  In addition to palpation, ultrasound and blood testing, milk testing is now being offered through DHIA testing centers.

In the April 2015 Wisconsin Agriculturist article Timing milk-based PAG pregnancy tests, UW-Extension St. Croix County Agriculture Agent Ryan Sterry explains how PAG tests work and how to incorporate a milk PAG test into a dairy operation’s management system.
