This study was intended to evaluate the nutritional value, antioxidant activity and digestibility coefficients of Pistacia atlantica seed and meal. The gas production experiment and batch culture degradability test were carried out to investigate the effects of Pistacia atlantica seed and meal on microbial fermentation characteristics, kinetics of gas production, methane and carbon dioxide production, t0.5, and lag time. Also, the calculated parameters e.g. microbial protein, molar proportion of volatile fatty acids, metabolizable energy (ME), short chain fatty acid (SCFA) and organic matter digestibility (OMD %), were evaluated for different treatments. The parameters were analyzed through the completely randomized design with repeated measurements. In this experiment, there was a significant difference in chemical composition (P <0.05). Although no significant difference was observed with respect to phenolic compounds, the amount of condensed tannin in seed was higher than that of meal (P <0.0001). Pistacia atlantica meal had the highest gas production rate (P <0.008). The number of moles of methane produced in 24 hours of incubation had a significant difference between the experimental treatments. Compared to meal, Pistacia atlantica seed had the lowest amount of methane produced (P <0.001). The total concentration of volatile fatty acids in seed decreased. The highest microbial mass was observed in seed (P <0.0003). The separation coefficient in the seed and meal were 6.48 and 2.92, respectively. Research shows that Pistacia atlantica seed and meal have a relatively good digestive potential and can be used in the diet of ruminants if properly planned.
