Effects of pre-slaughter transport stress on the microstructure of pork LT muscle during postmortem aging, (A) representative H&E staining images, (B) average muscle fiber gap, and (C) representative SEM images. Different letters (A-C) indicate a significant difference among aging time points at the same treatment (p < 0.05); Different letters (a, b) indicate a significant difference between two treatments at the same aging time (p < 0.05). TR: three-hour transport followed by three-hour resting treatment; T: three-hour transport treatment.
