Effect of replacing soybean meal (Glycine max) with sesame meal (Sesamum indicum) on productive traits, carcass characteristics, and gross profit margin in fattening lamb's diets.

The objective of this study was to determine the effect of replacing soybean meal (Glycine max) with sesame meal (Sesamum indicum) on productive traits, carcass characteristics, and gross profit margin (GMP) in fattening lamb's diets. For this, 42 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.
