Background One of the important by-products is sesame seed meal; it is a by-product of sesame seed pressing. Sesame oil cake or meal is a relatively good source of crude protein which can replace part of basic ingredients in diets such as soybean. Method Fifteen growing male Barki lambs aged 5–6 months (18.50 ± 0.98 kg) were used to investigate the influence of replacing soybean meal (SBM) that incorporated (16% of control ration) sesame meal (SM) at 50% or 100% on feed and water intakes, nutrient digestibility, growth performance, rumen parameters, and economic evaluation. Lambs received one of the three tested complete feed mixtures that contained 16% SBM (R 1 ), replaced 50% of SBM with SM (R 2 ), contained (8% SBM + 8% SM) or completely replaced 100% of SBM with SM (R 3 ) and contained 16% SM. Results Dietary treatments had no significant effect on all nutrient digestibility and total digestible nutrients value, meanwhile it decreased ( P
