Technical Abstract: An experiment was conducted to determine the effect of bird age, diet (feed formulated with either 69.5% corn, 69.7% milo, or 73.6% wheat), and feed withdrawal times (0 or 8 h) on color (CIE L*, lightness; a*, redness; and b*, yellowness) of raw broiler breast fillets. Broilers were placed on treatment diets at 28 d of age. Each day from 42-45 and 49-52 d of age, replicate groups of 24 birds (eight each from diet, four of which were either full fed or feed withdrawn) were slaughtered and eviscerated under simulated commercial conditions (n=192). Carcasses were chilled and fillets deboned 4 h postmortem. Triplicate color measurements were taken from the medial (bone) side of the fillet. Bird age did not significantly affect fillet color values (P<0.05). Fillets from the wheat diet were significantly lighter than the corn or milo diets (48.9 vs. 46.9 and 46.7, respectively). The milo diet resulted in significantly redder fillets than corn or wheat (3.9 vs. 3.5 and 3.3, respectively). The corn diet produced significantly more yellow fillets than milo or wheat (4.8 vs. 2.4 and 2.6, respectively). Feed withdrawal significantly increased fillet lightness from an average of 46.1 to 48.9, decreased redness from 4.1 to 3.1, and increased yellowness from 2.8 to 3.7. Diet and feed withdrawal may significantly affect raw broiler breast fillet color.
