Milk fat production is a key profit-driver for dairy farms, making it a focal point for producers and nutritionists. As the most variable milk component, herd-level milk fat percentage and yield are highly influenced by herd demographics, ration composition and feeding management. Milk fat depression is commonly defined as a reduction in milk fat yield with no change in the yield of milk or other milk components. When milk fat depression occurs, it can leave dairy producers questioning where to begin troubleshooting.
