TN-al: Birds reared under continuous 24°C and ad libitum feeding. cyHS: Birds reared under cyclic high temperature (8 h at 35˚C and 12 h at 24˚C) and ad libitum feeding. coHS: Birds reared under continuous 35°C and ad libitum feeding. TN-coPF: Birds reared under continuous 24°C and pair-fed to the coHS treatment.

SEM: pooled standard error of the mean.

Yields calculated relative to live body weight taken immediately prior to processing.

⁴

TBM: Total breast meat = P. major + P. minor.

^a-b

Means within row without a common superscript were determined to be significantly different (P < 0.05) by a Tukey's multiple comparison test.
