The aim of this study was to determine the effect of different levels of crambe meal (CM) in the diet as a substitute for soybean meal on feed intake, growth performance, blood parameters, carcass characteristics and meat quality of lambs. A total of 80 sheep predominantly from the Texel breed, 40 male (23.3 ± 0.98 kg) and 40 female (22.1 ± 0.95 kg) lambs, were fed 0, 64, 128 or 192 g/kg dry matter (DM) CM in the total mixed diet. Intake of DM increased in parallel with the level of CM inclusion in the diet and there was no effect of CM on digestibility and weight gain. The feed to gain ratio decreased as levels of CM increased in the diet. Yields of carcass and commercial cuts were similar among diets. The proportion of muscle and the muscle to bone ratio tended to decrease with higher CM level in the diet. Male and female lambs responded similarly to CM levels except for subcutaneous fat where there was a greater decrease in carcass of male than female lambs with increasing CM dietary level. Chemical composition and quality of the longissimus dorsi were similar among diets. These data suggest that there are no ill effects on carcass quality and animal performance when CM is provided at up to 192 g/kg DM in the diet of growing lambs fed a forage to concentrate ratio of 350–650.
