Popis: | The pre-slaughter handling and transport of pigs can cause stress and negatively affect the quality of meat. This article aims to investigate the impact of pre-slaughter stress on meat quality. The literature suggests that pre-slaughter stress has a significant impact on meat quality, resulting in lower meat pH, increased drip loss, and decreased meat tenderness. When the body experiences stress, cortisol triggers the liver to release glucose into the bloodstream, which provides energy for the body to respond to the stressful situation. Both serum cortisol and blood glucose levels increased post-slaughter, with a post-slaughter mean value of 7.28 µg/dl for serum cortisol (compared to the initial mean value of 6.08 µg/dl), while the blood glucose values revealed a highly catabolic state, with mean post-slaughter values of 143.24 mg/dl compared to 129.11 mg/dl mean pre-slaughter results. The study highlights a direct relationship between increased serum cortisol levels and blood glucose values when comparing the pre- and post-slaughter values with the normal reference ranges, with a highly significant correlation between the mentioned parameters (p |
