The effect of MalvaSylvestris on in vitro degradability and fermentation parameters of ArtiplexLeucoclada

This experiment aimed to investigate the effect of (zero, 20, 40 and 60 mg/kg Atriplex forage) malva sylvestris on digestibility and microbial fermentation of Atriplex in one-humped camel. Fermentation parameters by gas production technique and in vitro digestibility by two-stage digestion were measured by two years old female fistulated camels. Addition 40 and 60 mg/kg malva sylvestris increased gas produced from Atriplex forage (P<0.05). Gas production rate constant didn’t affect by malva sylvestris (P>0.05). Addition malva sylvestris (60 mg/kg) to Atriplex, significantly decreased partitioning factor, microbial biomass, the efficiency of microbial biomass and organic matter actually degradable (P<0.05). Addition of Malva sylvestris 40 and 60 mg/kg were significantly reduced medium pH (P<0.05). The compared with control the highest ammonia-nitrogen concentrations was for treatment containing 20 mg/kg malva sylvestris (11.37 mg/100 ml) (P<0.05). Also this treatment had the greatest NDF digestibility comparison to control (P<0.05). Adding malva sylvestris in 20, 40 and 60 mg/kg to Atriplex increased the protozoa population at 12 and 24 in comparison to control 48 h incubation (P<0.05). Species of Diplodinium camli, Diplodinium maggi, Epidinium ecudatum and Eudiplodinium maggi in treatments containing malva sylvestris were the highest. In conclusion, high fermentation malva sylvestris increase digestibility and gas production of Atriplex in one-humped camel diets.
