Two experiments were conducted to assess the addition of pistachio by-product biochar (PBB) to lactatingIn first experiment, the effects of the addition of different levels (0, 0.5, 1 and 1.5% diet on dry matter basis, DM) ofPBB on rumen fermentation parameters after 24h of incubation were investigated in a completely randomized designwith four treatments and three replications. Second experiment was designed to evaluate effect of feeding selectedlevel of PBB on performance and nutrient digestibility of 8 lactating Kermanian ewes in a Latin square change-overdesign with two 21-day periods. Methane production and ammonia-N concentrations decreased linearly (P<0.01), andpH increased linearly (P<0.01) as the dietary level of PBB raised. With the addition of 1%diet, milk yield, blood glucose, digestibility of DM increased (P<0.05) and blood urea nitrogen (BUN) decreased(P<0.05) compared to control group. In general, adding 1% of PBB to lactatingand digestibility of DM.
