This study was conducted to investigate the effects of different levels of yeast and molasses on chemical composition and nutritional value of Artiplex lentiformis silage. The levels of yeast include: zero (control), 2.5 and 5 g/kg dry matter and levels of molasses include: zero (control), 10 and 15 percent that were added to Atriplex and then ensiled. The experiment arranged in a factorial method (3×3) on based a completely randomized design. After determination of dry matter and chemical composition, gas production test and their parameters investigated in treatments. Results showed that adding the levels of 2.5 g/kg yeast, increased DM content and pH, and decreased WSC content of silage. Adding the levels of 5 g/kg yeast increased DM, ash, NDF, ADF and decreased OM, EE, WSC content and pH but had not significantly effects on CP content (P>0.05). Adding the levels of 10 and 15 percentage molasses decreased NDF and ADF content but increased DM and WSC content. Highest cumulative gas production at 96 h incubation was obtained in treatment 3 (53.22) and lowest cumulative gas production was obtained in treatment 4(43.24). The levels of 5g/kg yeast and %15 molasses produced the highest amount cumulative gas production, OMD and ME. The results indicate adding levels of 5g/kg yeast and levels of 15 percentage molasses to Atriplex lentiformis silage improve its nutritive value.
