Fifty-two male Kivircik lambs were used to investigate the influences of finish weight (LOW: 25–26 kg, MEDIUM: 30–31 kg and HIGH: 35–36 kg) and production system (CON: concentrate-based system, PAS: pasture-based system) on carcass and meat quality characteristics. CON lambs (n=27) were weaned at 76 d of age and then finished on concentrate feed and alfalfa hay until slaughter. PAS lambs (n=25) grazed on native pasture in the day-time and sucked their dams until slaughter. CON group grew 30% faster during the experimental period; therefore significantly fewer days were required to reach the target weight. CON lambs had higher cold carcass weight, cold dressing percentage, and produced fattier carcasses compared with those of PAS system. PAS lambs had lower meat lightness values than CON ones. CON system produced more tender meat than PAS system in terms of shear force and sensory evaluation results. Intramuscular fat of the PAS lambs had higher percentage of ∑PUFA and
