Carcass characteristics and meat quality
No effect (P N 0.10) of dietary RES supplementation was detected on
body and carcass weight, dressing percentage, LA, and last rib backfat
depth (Table 3). However, dietary RES supplementation decreased
(P b 0.05) the first rib, last lumbar vertebra and average backfat depths.
Although diet did not modify pH45 min, L*45 min, b*, and cook loss, increased
(P b 0.05) pH24 h and a* and decreased (P b 0.05) L*24 h, shear
force, and drip loss were observed with dietary RES supplementation
(Table 4). Carcass characteristics (Table 3) and meat quality traits
(Table 4) were not significantly different between the 300 and 600
mg/kg RES supplementation groups.
