This study involved two separate experiments to determine the effects of tannic acid and lignosulfonate treatments of sunflower seed meal on the digestibility and rumen degradability characteristics of some nutrients in rams. Sunflower seed meal was treated with 3, 6 and 9% tannic acid, 5 and 10% lignosulfonate. In the first experiment, the digestibility coefficients of dry matter, organic matter and crude protein of sunflower seed meal samples were determined by a faeces collection method using 5 merino rams aged 1.5 years and weighing 66.5 kg. Tannic acid treatments of sunflower seed meal at the level of 3, 6 and 9% did not have any effect on in vivo crude nutrient digestibility. Crude protein digestibility values were not affected by the treatment of 5% lignosulfonate of sunflower seed meal but were decreased significantly (p
