This study investigated the effects of dietary supplementation with walnut shell-derived biochar on growth performance, nutrient digestibility, and rumen fermentation characteristics in fattening male lambs. Twelve lambs (initial body weight: 34.4 kg) were randomly assigned to two dietary treatments: a control diet and a diet supplemented with 1 % walnut shell biochar, over a period of 60 days. The inclusion of 1 % walnut shell biochar did not significantly affect dry matter intake (DMI) (<em>p</em> = 0.08), average daily gain (ADG) (<em>p</em> = 0.06), or feed conversion ratio (FCR) (<em>p</em> = 0.47). However, lambs fed the walnut shell biochar diet had a higher final body weight compared to the control group (<em>p</em> = 0.05). In contrast, lambs fed the walnut shell biochar -supplemented diet showed significantly higher digestibility coefficients of organic matter (OM), neutral detergent fiber (NDF), and acid detergent fiber (ADF) (<em>p</em> < 0.05).
