Shokri , H . Zali , G .H . HeidariCollege o f Natural Resource , University o f Mazandaran , Sari , I ran , nae ＿ j li ＠ yahoo .comIntroduction One of the main objectives of range management is livestock production , which depends on the nutritive value ofavailable forage ( Stoddart et al . , １９７５ ) . Ganskopp and Bohnert (２００３ ) proposed that livestock and wildlife managers must beaware of the nutritional dynamics of forages to sustain satisfactory growth and reproduction of their animals , and assure fairvalue of the pasture . Feed quality has been defined as the amount of nutrient material that an animal can obtain from a feed inthe shortest possible time (Walton , １９８３ ) .Materials and methods Range species from rangeland in northern Iran were evaluated in this experiment including : Carexpendulus , Cyperus rotundus ? ,Lathyrus pratensis , Lathyrus apahca , Brachypodium sylvaticum and Alopecurus myosuroides .Samples were collected randomly from rangeland from northern Iran ( between the cities of Sari and Amol ) . Plants wereharvested in mid‐May at the early growth stage , transported to the lab , dried , and prepared for chemical analysis . Sampleswere analyzed for forage quality , CP ( crude protein ) , CF ( crude fiber ) , ME ( metabolism energy ) , DDM ( dry digestiblematter ) , ADF ( acid detergent fiber ) , DE ( digestible energy) , and TDN ( total digestible nutrients) .ResultsTable 1 Mean crude p rotein ( CP ) , acid detergent f iber ( ADF ) , metaboli zable energy ( ME ) contents and dry matterdigestibility ( DMD) o f f orage species in rangeland o f northern o f I ran .Cy perusrotundus Carex pendulaLathyrusp ratensisLathyrusaphacaBrachy podiumsylvatichumAlopecurusmyosuroidesCP ,％ １０ /３６ ± ０ /１４a ５ .９４ ± ０ /１b １８ /２１ ± /１６c １６ /０５ ± ０ /１４d ７ /８０ ± ０ /０５e １１ /６３ ± ０ /０７fCF ,％ ２１ /８５ ± ０ /３a ４０ /４２ ± ０ /４２d ３２ /４２ ± ０ /３２c ３３ /８３ ± ０ /９c ２４ /１５ ± ０ /３b ２１ /２７ ± ０ /４７aADF ,％ ３６ /６７ ± ０ /４２c ４０ /５５ ± ０ /３５d ３６ /４１ ± １ /２４c ３４ /９３ ± ０ /７７c ２４ /４３ ± ０ /９３a ２７ /９３ ± ０ /５７bTDN ,％ ５４ /１７ ± /４９b ４９ /７１ ± ０ /４a ５４ /４７ ± １ /４b ５６ /７ ± ０ /８８b ６８ /２５ ± １ /０７c ６４ /２２ ± ０ /６５dDDM ,％ ６０ .３２ ± ０ /３b ５７ /３０ ± ０ /２７a ６０ /５３ ± ０ /９６c ６１ /６７ ± ０ /６０c ６８ /２５ ± １ /０８d ６７ /１３ ± ０ /４４dME ,Mcal/ Kg １ .６６ ± ０ /０１ab １ /４６ ± ０ /０１a １ /８８ ± ０ /０３ab １ /８５ ± ０ /０２ab ２ /００ ± ０ /０４a １ /９３ ± ０ /０５abDE ,Mcal/ Kg ２ /０３ ± ０ /０１b １ /７９ ± ０ /０１a ２ /３ ± ０ /０４b ２ /２７ ± ０ /０３b ２ /４５ ± ０ /０５d ２ /３６ ± ０ /０６cConclusions Carex pendulus had the highest ADF , CF and lowest CP , DMD , ME , DE and TDN and , therefore , the lowestforage quality .
