Abstract

Abstract The objective of this study was to determine the effect of replacing soybean meal (Gly-cine max) with sesame meal (Sesamum indicum) in fattening lamb’s diets. For this, 44 Katahdin lambs were divided into three treatments in duplicate: basal diet + soybean meal (100S), basal diet + sesame meal / soybean meal (50 / 50SA) and basal diet + sesame meal (100A). Dry matter intake, daily weight gain (DWG), total kg gained (KgT), feed conversion (FC) and feed efficiency (FE) were evaluated, upon reaching the weight for sale, the animals were slaughtered, and hot carcass weight (HCW) was evaluated. The results were analyzed with a completely randomized design with repeated measures. Regarding time, no differences were found between treatments, for DWG (0.171 ± 0.006 kg/d), FC (6.7 ± 0.55), EA (0.175 ± 0.02), KgT (2.86 ± 0.13), RCC (50.97 ± 0.79), as well as for chest depth (26.96 ± 0.33), leg width (20.63 ± 0.028), leg diameter (60.7 ± 0.44), and ribs width (24.05 ± 0.14). Gross profitability margin (MUB) was 16.50%, 18.63%, 19.97% for 100S, 50 / 50SA and 100A respectively. Overall, in fatting lamb diets, replacing soybean meal with sesame meal by either 50% or 100% substitution could be a feasible feeding strategy as in both cases, gross profit was increased, and no negative effects were found for productive traits and carcass quality.
