Abstract :The aim of this study was to compare chemical composition, relative feed values, and in vitro true digestibility of the giant fennel insert ignore into journalissuearticles values(Ferula communicus L. -F);, helis insert ignore into journalissuearticles values(Prangos ferulacea L. -H);, gum- tragacanth insert ignore into journalissuearticles values(Astragalus microcephalus WILD. -G); and leaves oak tree insert ignore into journalissuearticles values(Quercus robur L. -O);, a naturally growing plant on the high- altitude plateaus of the Eastern Anatolia, with those of alfalfa. In vitro true digestibilities insert ignore into journalissuearticles values(IVTD); of roughages were determined with the Ankom DaisyII incubator. In terms of crude protein insert ignore into journalissuearticles values(CP); content, the lowest value was determined in H herb with 7.35 %, and the highest value was determined in alfalfa hay insert ignore into journalissuearticles values(A); with 19.28% insert ignore into journalissuearticles values(p<0.05);. G hay had higher acid detergent fiber insert ignore into journalissuearticles values(ADF); and neutral detergent fiber insert ignore into journalissuearticles values(NDF); content and O leaves had higher ether extract insert ignore into journalissuearticles values(EE); and condensed tannin insert ignore into journalissuearticles values(CT); content. While the lowest IVDMD were found in G hay insert ignore into journalissuearticles values(42.91%); and O leaves insert ignore into journalissuearticles values(56.22%); with the highest cell wall structural components and CT content, the highest digestibility value was determined for F insert ignore into journalissuearticles values(70.47%); and A insert ignore into journalissuearticles values(71.60%); insert ignore into journalissuearticles values(p<0.05);. Considering the analyzed parameters, it can be said that F hay is more suitable for ruminant feeding than other roughages.
