Fattening performance, slaughter, and carcass traits of Bafra ram lambs slaughtered at different weights were evaluated. A total of 40 lambs were fattened and 24 of them were slaughtered at four slaughter weights of 30, 35, 40, and 45 kg. The lambs showed decreasing fattening performance with increasing live weight. Dressing percentages and carcass compactness indices, as well as fat depots and back fat depth, were increased with greater slaughter weights. The proportions of individual cuts varied with slaughter weight; leg (P < 0.05), foreleg (P < 0.001), and loin (P < 0.05) percentages decreased while neck (P < 0.05) percentage increased. The percentages of carcass bone dropped (P < 0.05), but fat percentages rose (P < 0.001) as slaughter weight increased. The effect of slaughter weight on the lean/fat ratio was significant (P < 0.001), but the effect on the lean/bone ratio was non-significant. It was observed that the leg had the highest lean percentages, while the greatest fat ratio was ascertained in the breast + flank and back in all slaughter weight groups.
