At the 2024 Penn State Dairy Nutrition Workshop, Dr. Adam Lock from Michigan State University presented groundbreaking research on the benefits of feeding high-oleic soybeans (HOSB) to dairy cows. His findings showcased how HOSB can enhance milk production efficiency, improve feed value, and contribute to better overall dairy nutrition.
HOSB, a homegrown feed option in rich oleic acid, provides an economical source of 18-carbon fatty acids. Roasting and grinding these soybeans further increases their nutritional value by boosting undegradable protein and reducing anti-nutritional factors. This makes them an effective ingredient in dairy rations, with the potential to increase milk yield and optimize production efficiency.
Dr. Lock also explored the added advantages of combining HOSB with palmitic acid in feed diets. Research suggests that including 8-16% HOSB in dairy cow diets can significantly increase milk components such as butterfat, helping producers improve profitability by maximizing milk output relative to feed costs.
While these findings are promising, Dr. Lock emphasized the importance of ongoing research to refine feeding strategies. In particular, the transition and early lactation periods require careful study to fully understand the role of HOSB in supporting cow health and productivity.
This research highlights the potential of HOSB as a valuable and sustainable feedstuff, offering producers an opportunity to enhance the efficiency and nutritional quality of their dairy operations.
