Özet

Physical, chemical and organoleptic characteristics of 20 ram lambs representing four fat-tailed genotypes Awassi, Red Karaman, Tushin and Awassi x Tushin were compared. After slaughter, carcasses were chilled at 5 degreesC for 24 h, graded and evaluated. Then, the carcasses were dissected into wholesale cuts and longissimus dorsi (LD) and semimembranosus (SM) muscles were excised. The muscles were subjected to moisture, protein, fat and ash analyses and they were cooked to evaluate palatability. Cold carcass weight of RK and A x T lambs were heavier (P < 0.01) than those of A and T lambs. A x T crossbreds had higher (P < 0.05) cold dressing percentage and larger LD area than T lambs. However, the influence of genotype on the proportion of boneless retail cuts and marbling were not significant. Most of the proportions of wholesale cuts except for sirloin and Rank were not affected by the genotype. The sensory panel found the meat from all genotypes acceptable (tenderness. juiciness, flavor and acceptability). Chemical composition of meat from the different genotype was not significantly different. The study reveals generally insignificant differences in chemical, physical and organoleptic properties between fat-tailed lambs with different genetic backgrounds. (C) 2001 Elsevier Science B.V.
