Guests: Dr. Usman Arshad, ETH Zürich; Dr. Bill Weiss, The Ohio State University Professor Emeritus Dr. Arshad begins by reviewing the inclusion criteria in the meta-analysis he conducted. He wished only to look at studies where lysine was supplemented in a rumen-protected form. The meta-analysis did not include studies that infused lysine into the abomasum or intestine. In addition, only completely randomized design or randomized complete block design studies were included. Feed ingredients and chemical composition of diets for each experiment were run through NASEM to predict the metabolizable lysine content using the same model so all studies were on the same scale.
