among genotypes. Joseph et al. (1997) reported that fat
loss from high temperature (85°C) caused increasing
fluid loss in meat, but the internal temperatures of the
samples investigated in the current study did not exceed
80°C. One exception for genotype differences in waterholding
capacity was that the thigh meat of Black-boned
chickens had higher (P < 0.05) grilling losses than that
of Bresse chickens, with the other genotypes ranging in
between. This may have been the result of the small size
of the muscles of the Black-boned chickens (grilling loss
was numerically highest also in breast muscle), making
it easier to lose water compared with larger pieces of
meat (Jaturasitha et al., 2004a).
