We sit down with Dan Carroll, STgenetics Dairy Program Manager, to learn more about the upcoming Genetic Base Change that will begin during the April 2025 Genetic Evaluations. Dan explains the significance of the five-year base change, which resets the cow population base to animals born in 2020, and how it indicates impressive genetic progress. Learn about the changes to the Net Merit formula and the impact these adjustments will have on the ranking and quality of dairy breeds, particularly Holsteins. Dan also offers advice to dairy breeders on navigating these changes and making informed genetic decisions.
