This episode was recorded in Reno, Nevada, during the 2025 Western Dairy Management Conference. The panel is reviewing a presentation given by Dr. Rick Grant, who was unable to be on the podcast. The presentation was based on the idea that crowding is a subclinical presence. If you manage it with people and resources, a dairy can do very well. But if something happens in that crowded situation, like a disease or heat stress, it can tip performance over the edge. Evaluating time budgets for cows can

This episode was recorded in Reno, Nevada for the 2025 Western Dairy Management Conference. Dr. Shabtai gives an overview of her presentation. Afimilk has a new technology that includes a feed efficiency sensor to determine eating, rumination, heat stress monitoring and more. The Feed Efficiency Service combined with the AfiCollar can estimate dry matter intake, which, when combined with Afimilk’s milk meter data, yields an efficiency value of milk income over feed cost for each cow. She details how

In times of limited forage, dairy producers may need to feed diets lower in forage than is typical but would like to maintain milk production. In this study, two diets similar in neutral detergent fiber (NDF), starch, and crude protein with different amounts of forage were fed to 32 mid-lactation Holstein cows in a crossover design. The control diet (CON) contained high forage (55.5% of diet dry matter) with no supplemental fatty acids or amino acids. The low-forage diet (LF) contained 36.6% forage
