Choline, a pseudovitamin, is required by all mammals including the dairy cow for many essential functions. Research in supplementing rumen protected choline really took off about twenty years ago, however continues today to best understand how this feed through additive can positively influence profitability. Dr. Usman Arshad joins the conversation for this episode to highlight his comprehensive summary of all the peer reviewed, published research completed on Choline. Listen in to best understand the assumed mode of action choline uses to help provide an improved efficiency in milk production for the majority of the lactation, even when only fed during the 42-day transition period.
The findings we discuss are published in the recently released paper titled: Exploring choline's important roles as a nutrient for transition dairy cows
