Nutritional and anti-nutritional value of six local forage legume species accessions (Medicago truncatula, Medicago ciliaris, Hedysarum coronarium (cultivar Bikra 21), H. carnosum, Lathyrus cicera and Scorpiurus muricatus ssp muricatus (cultivar haffouz) was investigated. Dried samples of each accession were analyzed for NDF, organic matter, crude protein (CP), soluble nitrogen contents in pepsin, non-protein nitrogen, soluble nitrogen in the buffer and non-digestible nitrogen (N-ADF), total phenols, total and condensed tannins. Biological parameters were determined using in vitro gas production technique. Except from Hedysarum coronarium, all species had a CP content ranging between 200 and 230 g kg-1 DM. The proteins of all species are of good quality as suggested by low proportion of fiber-bounded and soluble nitrogen. Secondary compounds had no negative effect on nutritive value of the six species, even for the case of Hedysarum coronarium which had relatively high level of condensed tannins (37 g kg-1 DM). High gas production registered during fermentation and real degradability (superior to 70%) suggest that studied species present an excellent forage quality potential
