Adisseo continues to raise awareness on the significant benefits of meeting requirements for essential nutrients. However, there is still work to be done when it comes to supplying the industry with accurate data on metabolizable amino acid contribution from rumen-protected products. In this Feedinfo article, we talk to Dr. Chuck Schwab (Professor Emeritus, University of New Hampshire, and Principal, Schwab Consulting) and Dr. Brian Sloan (Global Director of Ruminant Amino Acids and Protected Nutrient Business, Adisseo). Drs. Schwab and Sloan advocate for a robust, accurate, and precise technique to measure the metabolizable contribution of each commercial rumen-protected product for dairy cows.
