As the cornerstone of dairy farming, genetic selection can significantly influence herd performance and profitability. This article illuminates the intricacies of the U.S. Genetic System, offering insights into data-driven decisions to optimize breeding outcomes. We delve into Breeding Value vs. Predicted Transmitting Ability (PTA), examine the roles of the Council on Dairy Cattle Breeding (CDCB) and Holstein USA, and explore how technology and data collection shape future dairy genetics. Emphasizing the significance of TPI and Net Merit indices, this discussion underscores the balance of proven and genomic young bulls, the importance of phenotypic data collection, and the aim for sustainability and output in dairy herd management.
