This study was conducted to compare forage quality of two native halophytespecies Camphorosma monspeliaca and Limonium iranicum collected from Meighansaline rangelands near Arak city in center of Iran. Edible biomass of both species wassampled on three phonological stages (vegetative growth, full flowering and seedripening). Forage quality indices such as Crude Protein (CP), Dry Matter Digestib...

Information on forage quality could help rangeland managers to select suitable grazing method to achieve higher animal performance without damage to vegetation. The aim of this study was to determine and compare the forage quality of S. yazdiana and S. tomentosa, which are the most important species of saline rangelands in Ardakan in Yazd province, Iran. These two species are grazed by goats an...
