Dr. Joseph McFadden: Methyl Donor Nutrition for Dairy Cattle | Ep. 150
In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Joseph McFadden from Cornell University explains how methyl donors support transition cow nutrition. He discusses methionine, choline, omega-3 fatty acids, bioavailability, oxidative stress, and liver function, and examines why nutrient interactions matter beyond individual supplementation strategies. Listen now on all major platforms!
"You feed a methyl donor like methionine or choline, and you think everything is going to be great in terms of liver health. But if youโre missing another key component, like omega-3 fatty acids, then you can limit the expected metabolic response."
