This experiment aimed to investigate the supplementary effect of 0, 20, 40 and 60 mg/kg Malva sylvestris on protozoa species, digestibility and microbial fermentation of Suaeda fruticosa plant in the rumen liquor of one-humped camel. Fermentation parameters were measured by gas production technique and in vitro digestibility by two-stage digestion using rumen liquor from two female fistulated dromedary camels. Protozoa species was studied in vitro gas production condition. The results showed that addition of Malva sylvestris linearly increased gas production potential and rate constant from Suaeda fruticosa forage in camels (P<0.05). Addition of Malva sylvestris at 60 mg/kg dry matter to Suaeda fruticosa, significantly decreased partitioning factor, microbial biomass and the efficiency of microbial biomass (P<0.05), while organic matter digestibility linearly increased, but had no influence on cell wall degradability (P>0.05). Treatments containing Malva sylvestris (40 and 60 mg) significantly reduced ammonia-nitrogen linearly (P<0.05) but didn’t influence pH and total protozoa population (P>0.05). Digestibility of DM (dry matter) and NDF (neutral detergent fibre) and species of Diplodinium cameli in treatments containing Malva sylvestris were the highest but species of Diplodinium ecaudatum decreased in camels (P<0.05). Therefore, the results indicated that addition of Malva sylvestris improved digestibility and gas production with a decrease in ruminal ammonia-N concentration; that Malva sylvestris supplementation can be used to improve the nutritional value of Suaeda fruticosa forage in dromedary camel.
