Effects of cold stress on the ultrastructure and enzyme activity of the longissimus dorsi muscle in LW and MS pigs at 25 °C and 4 °C. (A) Transmission electron micrographs of longissimus dorsi from LW and MS pigs at 25 °C and 4 °C, whereby the top panels and bottom panels show low (scale bar 5 μm) and high magnification (scale bar 1 μm), respectively. Yellow triangles and ‘M’ represent mitochondria. (B) Succinate dehydrogenase (SDH) activity staining and (C) lactate dehydrogenase (LDH) activity staining of longissimus dorsi muscle tissue in LW and MS pigs at 25 °C and 4 °C (scale bar 200 μm). The results are expressed as mean ± SEM (n = 3). LW and MS represent Large White pigs and Mashen pigs, respectively; 25 and 4 refer to 25 °C and 4 °C, respectively. p values were determined using the two-tailed unpaired Student’s t-test. ** p < 0.01.
