Resumo
The objective of the experiment was to evaluate the
quantitative carcass characteristics of crossbred Charolais-
Nellore males with similar slaughter and carcass weights
and subcutaneous back fat thickness, feedlot finished and
slaughtered with 22 month (steers) or 13 month (young
steers). The slaughter and carcass weights and subcutaneous
fat thickness were 332.92 kg, 180.30 kg and 3.08 mm and
331.42 kg, 187.39 kg and 2.94 mm, respectively, for steers
and young steers. The complete randomized experimental
design, with twelve replicates, was used. Young steers
showed higher hot carcass dressing (56.56% vs 54.20%).
Cold carcass dressing was also higher for young steers
(55.11% vs 52.63%), as a consequence of their higher hot
carcass dressing and lower chilling loss (2.64% vs 2.98 %). Carcass metric characteristics, carcass and arm length,
were similar for the two categories. However, steers
had longer legs (67.92 vs 63.33 cm). Young steers were
superior for characteristics related with carcass muscling,
like conformation (10.42 vs 8.92 points), cushion thickness
(24.38 vs 21.96 cm), and Longissimus dorsi area (61.58
vs 55.51 cm2). No significant difference between the two
categories was observed for the absolute and relative
values of the commercial cuts, forequarter, sawcut and
ribs.
