An effective cow and heifer breeding program is key to maximizing your long-term profitability. Extended calving intervals can quickly lead to lower overall production and higher reproductive culling rates, which is why it is important to identify open cows as swiftly and accurately as possible. Adding a milk-based pregnancy test to the pregnancy checking protocol may be the tool to do just that.

To address these issues, there are tools and strategies available that can help the producer make a good decision for their unique situation.
