-- The objective of this study was to determine the variation of the meat pH in the first 24 hours after death in the carcasses pork slaughter by electrical stunning and in the carcasses pork slaughter without stunning. A total of 446 porks, were distributed in 2 groups: 223 slaughter animals with electric stunning and 223 slaughter animals without electric stunning (78 males and 145 females for each group respective), with similar characteristics in management, age and genetic line. pH measurement was done in carcasses in semimembranosus muscle of the left leg, in the first hour post slaughter and later each 2 hour by a period of 24 hours in refrigerating conditions. It was determined that electric slaughter influence in the initial and final pH values, getting lower initial pH in the animals slaughter with electric stunning (6.54) than that of the animals slaughter without stunning (6.75) and a higher final pH in the slaughter animals with electric stunning (5.90) than that of the animals slaughter without electric stunning (5.55). There was also determined the sex influence in the final pH value, obtaining a higher final pH in males than in females, 6.00 and 5.44 respectively for the group of the slaughter animals with electric stunning, 6.00 and 5.24 in males and females respectively for the slaughter animals without stunning.
