A prime example of this evolution is seen at McCarty Family Farms, which has leveraged genetic enhancements to achieve a remarkable leap in productivity. By implementing rigorous genomic strategies, the farm has increased daily milk output per cow from approximately 70 lb. to over 100 lb. Crucially, even while expanding their herd from 7,000 to nearly 20,000 cows, they have boosted overall productivity by almost 50% since 2011. This success underscores the philosophy that “You can’t manage what you can’t measure,” making objective data essential in modern dairy economics.

The impact of this genetic focus extends significantly into herd health and milk quality. Genomic insights have allowed the McCartys to reduce disease rates and improve animal welfare, resulting in superior quality milk with somatic cell count averages between 120,000 and 180,000. Furthermore, efficiency indexes like TPI and DWP$ (Dairy Wellness Profit Index) are critical in managing the 65% portion of the budget dedicated to feed, guiding precise mating strategies that ensure better animal performance and lower operational costs per unit of output.

A central tenet of the McCarty’s breeding strategy is the genetic enhancement of milk protein content, which is notably harder to improve via diet than butterfat. This focus on protein not only caters directly to customer demand but also serves a powerful sustainability purpose. According to the farm’s management, the single largest action they can take to drive down their carbon footprint is increasing output, confirming that higher productivity and sharper breeding strategies directly benefit both the bottom line and environmental metrics.
