A series of N‐substituted methionine derivatives were investigated for their potential to resist rumen degradation but still to release methionine in the duodenum. The method adopted was (a) to measure rumen methyl mercaptan concentrations in sheep following intraruminal doses of the materials and (b) to measure the ability of the materials to promote the growth of chicks receiving a methionine deficient diet.
