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.

With the arrival of lower-cost genomic testing options, an increasing number of registered purebred and commercial producers are using these tools for routine sorting and selection applications.

While genomic testing costs have come down, they can still be substantial, and dairymen are searching for the most cost-effective applications of the technology. To address these issues, there are tools and strategies available that can help the producer make a good decision for their unique situation.

Do the continually changing industry selection indexes and recent genetic base change have you questioning what that means for your genetic plan?

The recent genetic base change caused an industry-wide rollback for most traits for all bulls, cows and heifers. Previously, we determined proof values for a sire by comparing his daughters to the average cow born in 2005.

Physically, I was getting so I couldn’t do it anymore.”

Cow with calvesIn vitro fertilization (IVF) is finding its place on commercial dairies, but the way it is being used may come as a surprise.

IVF technology is not new to the dairy industry. For years, it has been used to increase the number of offspring from genetically elite females. These were often hand-picked, high-type show cows or off-the-charts genomic animals. IVF opened a window of opportunity to harvest oocytes and, ultimately, make more embryos from these top-tier cattle.
