Vetch

Abstract

Common vetch, Vicia sativa L, is an annual grain legume species and a member of the Vicieae tribe. Generally grown as a mix for hay production or grazing, vetch has considerable potential as a grain and forage legume as the seed contains high protein levels. Although the seed has also been used for human consumption, several common accessions contain β-cyanolalanine and its γ-glutamyl peptide derivative, which are neurotoxic to monogastric animals. Traditional breeding methods reduced seed toxin levels from 1.15% to between 0.3% and 0.4% of total seed protein, however, due to accumulative effects, much lower or zero levels are required to ensure safe consumption. This may ultimately be achie..
