It’s important for poultry sector’s stakeholders to master the effect of intrinsic and extrinsic conditions on meat quality. The objective of this study was to evaluate the influence of muscle type on meat quality of local chickens from Benin according to preslaughter transport conditions and sex. It involved thirty-six chickens of 6 to 7 months from the two sexes comprising a control group, a slaughtered after 4 hours of rest following 2 hours of transport group, and an immediately slaughtered after 2 hours of transport group. Data on meat acidity and color were collected and an analysis of variance was performed using R software. In the three groups, the thigh pH was higher than that of the breast at several measure times (p < 0.001), namely 5.76 vs 5.35 in non-transported chickens, 5.76 vs 5.38 in 4-hour of rest chickens, and 5.86 vs 5.47 in immediately slaughtered chickens at 48 hours post-mortem. This same trend was observed for the red index (a*) at both measure times in 4 hours of rest chickens (8.15 vs. 6.12 and 8.15 vs. 7.04) and on the slaughter day in the immediately slaughtered after transport chickens (7.78 vs. 6.45) (p < 0.001). Meanwhile, the yellow index (b*) and, to a lesser extent, lightness (L*) and chroma of the two muscles showed an opposite trend to that of the red index (p < 0.001). These trends of pH and color indices between thigh and breast were also observed in both sexes for the three transport conditions. Then, whatever the sex or the preslaughter transport condition, breast meat is more acidic, more yellowish, and relatively brighter, but less red than thigh meat.
