Abstract: | The effects of three finishing systems on carcass composition and other characteristics of meat were studied in 15 young Eastern Anatolian Red bulls in Eastern Turkey. For 93?days, five bulls grazed pasture (P), five grazed the same pasture and were given concentrate supplementation (P + C), and five grazed the same pasture for 93?days, and then for an additional 40?days, they received concentrate in a barn (PF). Carcasses of the P bulls were lighter and leaner than those of the PF animals. Compared with the P carcasses, PF carcasses had a greater percentage of kidney, pelvic, and heart fat (P?0.05), marbling score (P?0.05), fat thickness over the longissimus dorsi (LD) muscle (P?0.05), and percentage of ether extractable lipids (P?0.05). The LD of P carcasses was darker (P?0.01) in color and the meat was tougher. The ratio of polyunsaturated to saturated fatty acids in LD intramuscular fat was higher (P?0.05) for P bulls than for P + C and PF. P carcasses contained a lower (P?0.05) proportion of saturated fatty acids than PF carcasses. It is concluded that pasture-based finishing results in a more favorable fatty acid profile of meat and produces a healthier food, but the meat is darker and tougher. |
