Episode Details

The dairy industry is shifting from focusing on liquid milk volume to enhancing valuable components like butterfat and protein. Driven by advancements in genomics and the strategic use of sexed semen, this evolution has led to significant genetic progress, particularly in breeds like Holstein cattle, where productivity in butterfat and protein has seen remarkable gains—28.9% and 22.9%, respectively, by 2023. Despite these advancements, the USDA’s Milk Production report has lagged in capturing the accurate growth trajectory of milk components, providing an outdated view. With over 80% of milk now directed towards manufactured products, reports are urgently needed to accurately reflect these changes and capture the industry’s current economic focus. Redefining milk production reports and incorporating accurate body weight data in genetic evaluations can help create efficient, sustainable herds that meet modern environmental, economic, and consumer demands. https://www.thebullvine.com/technology/from-milk-machines-to-component-champions-how-genomics-and-sexed-semen-are-remaking-the-dairy-cow/
