Dr Tom Tylutki, CEO AMTS

Formulating for Profit and a better Environment

Our own, Tom Tylutki, will use the CNCPS-based AMTS formulation model to look at the effect various feeds and diets will have on emissions. The excretion and emission equations in the CNCPS allow you to formulate with those results in mind. Tom will demonstrate, using real diets, ways to consider emissions in formulation. What are the best strategies. This will be very hands on; for more of Tom’s past formulation focused webinars; look at 2015, 2016, 2020, Feb 2021, and Oct 2021
