Abstract: Cortisol is a steroid hormone that regulates a wide range of vital processes throughout the body, including metabolism and the immune response. It also has a very important role in helping the body respond to stress. Numerous studies have been conducted around the world to compare the development rates of pigs raised indoors to those raised outdoors, but the results have been ambiguous and, in many cases, conflicting. The objective of this study was to determine the effects of various housing systems (indoors … Show more

This study aimed to investigate the impact of pig breed on stress levels and meat quality in two commercial pig farms in the north-eastern part of Romania. One farm raised 52 Mangalita pure-bred pigs and the other 82 Duroc x Landrace crossbred pigs. Serum cortisol, a biomarker of stress, and serum glucose were measured before and after slaughtering, while meat pH was measured at 45 minutes and 24 hours post-mortem. Results showed that the Duroc x Landrace crossbred pigs had higher serum cortisol and glucose values before and after slaughtering compared to the Mangalita purebred pigs. The meat pH values of the two breeds were similar, with the pH45 and pH24 values being 6.67 and 5.48 for Duroc x Landrace crossbred and 6.53 and 5.52 for Mangalita purebred, respectively. These results suggest that pig breed can have an impact on stress levels and meat quality, with Duroc x Landrace crossbred pigs showing higher stress levels and meat quality being not affected by the breed of pig. Further research is needed to confirm these findings and to understand the underlying mechanisms.

The COVID-19 pandemic has ushered in unprecedented changes in the lives of humans and their companion animals, impacting their daily routines, social interactions, and stress levels. This study investigates the effect of pandemic-related restrictions, including limited time outside and changes in owner habits, on the stress indicators of 34 dogs and 29 cats. Cortisol levels, total leukocyte counts, eosinophil counts, and behavioral changes have been analyzed to assess how these species are differentially affected by the altered environment and human interactions during the pandemic. The study revealed important behavioral changes in cats while the biochemical and hematological parameters were considerably affected in dogs. Our findings shed light on the unique stress experiences of dogs and cats and underscore the importance of considering individualized strategies for managing their well-being during extraordinary circumstances.

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<0.01). The article also explores potential pre-slaughter indicators such as cortisol and blood glucose levels for predicting stress and meat quality in pigs. Improving pre-slaughter handling and reducing stress can lead to improved meat quality and economic benefits for the pork industry. In terms of pH24, a trust coefficient of 5.46–5.50 revealed the impact of pre-slaughter stress on meat pH, resulting in possible inferior meat in terms of quality. The study results showed a highly significant correlation between the cortisol and blood glucose values recorded post-slaughter and pH24 (p<0.05), emphasizing the impact of stress on meat quality and suggesting that both serum cortisol and blood glucose values can be used as specific indicators of meat pH and ultimately meat quality.
