Verificaram-se as caracter赤sticas de carca as de 23 cordeiros Corriedale, 25 Bergam芍cia-Corriedale (BC) e 17 Hampshire Down-Corriedale (HC), terminados em pastagem de Cynodon dactylon ou no confinamento. As m谷dias para pesos das carca as quentes (PCQ): 13,37 e 11,94 kg, das carca as frias (PCF): 12,92 e 11,45 kg, dos rendimentos verdadeiros (RVC): 49,07 e 46,95% e comerciais das carca as (RCC): 42,59 e 38,27%, dos 赤ndices de compacidade das carca as (ICC): 21,88 e 19,21 kg cm-1 e do rendimento da costela (RC): 10,32 e 9,40% foram superiores para cordeiros terminados em confinamento, que tamb谷m apresentaram menor perda de peso porresfriamento (PPR): 3,35 e 4,11%. As m谷dias para 赤ndices de compacidade da perna (ICP = 48%) e rendimentos da perna (RP = 33,23%), do lombo (RL = 9,72%), das costelas descobertas (RCD =11,33%), dos baixos (RB = 11,48%) e do pesco o (RPC 5,95%) n o foram afetadas pelos sistemas de termina o. As carca as dos Corriedale e HC foram semelhantes para PCQ e PCF e inferiores aos BC. O RVC foi superior para BC (48,87%). Para RC e RB, os HC mostraram-se superiores aos BC, que tamb谷m foram superiores aos Corriedale. A perda de peso por resfriamento, o rendimento comercial da carca a, o 赤ndice de compacidade da perna, os rendimentos da perna, da paleta, do lombo, das costelas descobertas e do pesco o n o sofreram efeito de cruzamentos (P%26gt;0,05). O sistema de termina o teve maior influ那ncia que o cruzamento nas caracter赤sticas quantitativas das carca as dos cordeiros, com superioridade para os confinados. The goal of the experiment was the study of carcass characteristics of 23 Corriedale, 25 Bergamacia-Corriedale (BC), and 17 Hampshire Down-Corriedale (HC) lambs, finished on pasture (Cynodon dactylon) or in dry-lot. The means for hot carcass weight (HCW) were 13.37 and 11.94 kg; for cold carcass weight (CCW) were 12.92 and 11.45 kg; for biological carcass yield (BCY) were 49.07 and 46.95%; for commercialcarcass yield (CCY) were 42.59 and 38.27%; for carcass compactness (CC) were 0.219 and 0.192 kg cm-1; and for rib yield (RY): 10.32 and 9.40%. The values were higher for dry-lot lambs, which also presented lower (P%26lt;0.05) cooling loss (CL): 3.35 vs. 4.11%. The average for ham compactness (HC = 0.48) and ham yield (HY = 33.23%), loin (LY = 9.72%), uncovered rib (URY = 11.33%), bass (BY = 11.48%), and neck (NY = 5.95%) were not affected by the finishing system. The Corriedale and HC were similar in terms of HCW and CCW, and lower to BC. There was a difference for commercial carcass yield among genetic groups, with superiority for BC (4
