Abstract
In order to study thechanges of seasonal production and consumption of range species during the growing period and grazing season, SarAliAbad rangelands were selected, representing a semi-steppe area. Production was measured inside an exclosure and consumption was estimated outside the exclosure under livestock grazing during 2007-2011. Collected data were analyzed by SAS software and mean comparisons were done by Duncan's multiple range test. Results indicated that there were significant differences between production and consumption at P Festuca ovina with an average production of 161 kg/ha and an average consumption of 172 kg/ha, and Agropyron intermedium with an average production of 57 kg/ha and an average consumption of 64 kg/ha, respectively.
