In present experiment fermantability of three halophyte species including: Atriplex leucoclada (AL), Suaeda fruticosa (SF) and Seidlitzia rosmarinus (SR) in the form of individually or mixed as 0.0, 33.5 66.5 and 100% with each other (9 diets), were evaluated using a compelet randomized design. These halophyte species were collected from southern rangelands of Khuzestan province during autumn and winter grazing season. The diets were different regarding the rate and amount of gas producedtion (P<0.05). The AL produced lowest but diet containing 66.5 SF+ 33.5 SR (T8) had highest gas production compared with other diets (P<0.05). Diet containing AL and SR respectively had the lowest and highest true OM digestibility, true fermentable OM, total volatile fatty acid, ME and maximum microbial mass production (P<0.05). The fficiency of microbial mass production in AL was the highest and the lowest efficiency was for T8 diet. Concentration of rumen ammonia nitrogen with feeding all diets was higher than its threshold level, so they prepare enogh amount of ammonia nitrogen for maximum. Microbial biomass production. Therefore, diets T5 and T8 were the best diets to provide the nutrients requirements of camels; but from of range improvement poit of view combined diets are preferred than each of the three plants alone.
