Abstract

Present study was carried out to determine the chemical composition and DEGRADABILITY parameters of Dry Matter (DM), Acid Detergent Fiber (ADF), Neutral Detergent Fiber (NDF) and Organic Matter (OM) in AGROPYRONTAURI, which isa dominant rangeland plant in Neor region (Ardabil province). Plant samples were collected at 3 stages including: vegetative growth stage, flowering stage, seeding stage and in two different elevations.30 plants from each stage were collected and evaluated. Ruminal DEGRADABILITY of samples was determined by in situ technique using two ruminalcannulated Moghani rams. There were significant differences between average amount of DM, NDF, ADF, Ash contents; and their DEGRADABILITY of DM, ADF, NDF and OM including rapid degradable portion (a), slow degradable portion (b), constant rate of DEGRADABILITY (c) and Effective DEGRADABILITY (ED) in DIFFERENT PHENOLOGICAL STAGES (P<0.05). Results showed thatby developing phenological stages the average amount of DM, EE, Ash contents and parameters of DM and NDF DEGRADABILITY were decreased, however the mean amount of ADF, NDF and OM were increased (P<0.01). The highestaverage amount values for a and b portions of DM were observed in vegetative growth stage, however the lowestaverage amount values were in seeding stage. Moreover, effect of height on NDF and DEGRADABILITY parameters of DM and NDF was significant (P<0.05). Generally, present study showed that maturity of plant led to decrease in amount of rumen DEGRADABILITY and NUTRITIONAL VALUE of plants.
