A hundred and twenty-five castrated Iberian pigs (61 males and 64 females, from 106.9 kg of live weight at star to 160.3 kg at slaughter) was used to investigate the effect of feeding system on carcass attributes (backfat thickness and loin area measured with ultrasound before slaughter, and intramuscular fat and weights and yields of hams, forelegs and loins after slaughter). Pigs were fattened outdoor under extensive conditions. There were 4 treatments: "montanera", M; "recebo", R; "cebo a campo", C; and high oleic fed, O). Ultrasound images were collected at two rib locations (10th and 14th). M and O groups had the highest fat thickness and loin area was lower in M than in C group. M and O showed higher carcass weight and yield than the other groups. The largest ham weight was for C and the lowest for M groups. Loin weight and yield were higher in M and R than the other two groups (O and C).
一百二十五头去势伊比利亚猪（61 头公猪和 64 头母猪，从出生时的 106.9 公斤活重到屠宰时的 160.3 公斤）用于研究饲养方式对胴体特性（屠宰前用超声测量的背膘厚度和腰肉面积，以及屠宰后肌肉内脂肪以及火腿、前腿和腰肉的重量和产率）的影响。猪在户外露天条件下进行育肥。有 4 种处理方式：“montanera”，M；“recebo”，R；“cebo a campo”，C；和高油酸饲料，O）。在两个肋骨位置（第 10 和第 14 个）采集超声图像。M 和 O 组的脂肪厚度最高，M 组的腰肉面积低于 C 组。M 和 O 组的胴体重和产率高于其他两组。C 组的火腿重量最大，M 组的火腿重量最小。M 和 R 组的腰肉重量和产率高于其他两组（O 和 C）。
