“…These responses might be explained by a impact of cortisol. In fact, in lambs, injection of cortisol induced a significant increase of glucose metabolism, temperature, pH and WHC of fresh meat (Pighin et al, 2013). In addition, WHC, proteolysis, lipid oxidation and color of meat are largely influenced by the Postmortem pH and temperature kinetics of muscle, and are able to determine the sensory aspects of meat, then the satisfaction of the consumer (Bee et al, 2007;Ferguson et al, 2008).…”

Relationship between serum levels of cortisol at slaughter and changes of some parameters of meat was investigated in 50 male camels, during ageing for 10 days at 4±1°C. Blood was sampled at slaughter to determine serum levels of cortisol and oblique abdominal external muscle was collected after slaughter to analyze pH, electrical conductivity (EC), drip loss (DL), cooked loss (CL), moisture, solids, ashes, protein total, calcium (Ca), phosphorus (Pi), magnesium (Mg), sodium (Na), potassium (K), catalase activiry (CATa), malondialdehyde (MDA), shrinkage, R-value and total haem pigment (THP) at days 0 (four hours postmortem), 5 and 10 of refrigerated storage. The camels were divided into 3 groups (Gr) with different serum levels of cortisol at slaughter (low, high and very high levels): Gr1 (13.07-67.9 ng/mL, n= 24), Gr2 (80.29-107.21 ng/mL, n= 7) and Gr3 (133.7-198.04 ng/mL, n= 19). Compared to Gr1, Gr2 and Gr3 had a significant (P<0.05) increase of pH, EC, DL, CL, THP, dimensional shrinkage and MDA, and a significant (P<0.05) decrease of CATa at the 5th and 10th postmortem days. However, the bleeding efficiency, moisture, ashes, R-value and levels of Ca, Pi, Na, K and total protein showed no significant differences between twoo cortisol groups. The antemortem circulating levels of cortisol were positively correlated with postmortem pH, EC, DL, CL, THP, dimensional shrinkage and MDA, and negatively correlated with CATa. The analysis of circulating cortisol at slaughtering may predict the quality and oxidant stress status of camel meat during postmortem cold storage.

“…Blood samples were centrifuged at 1,500 G, the serum was removed, and then it was frozen at −20°C. Cortisol concentration was analyzed with a commercial enzyme-linked immuno assay (ELISA) kit (Cortisol KAPDB 270, Dia Source Immunoassay SA, Belgium), widely used in ungulates (Pighin et al, 2013(Pighin et al, , 2015. Lactate concentrations were calculated with a commercial enzymatic kit (L-Lactate, manual procedure, RANDOX Ltd., Crumlin, Co. Antrim, United Kingdom).…”

The management of wild vicuñas can trigger a stress response that may compromise welfare. In Santa Catalina, Jujuy Province, Argentina, indices of short-term stress associated with capture, handling, and shearing were studied in 105 wild vicuñas (Vicugna vicugna). The study included 2 groups (n = 59 and n = 46) of wild vicuñas captured in 2 consecutive days. Independent variables analyzed included sex, restraint time, and groups. Cortisol, creatine kinase, glucose, white blood cells, temperature, heart rate, and respiratory frequency were higher than published values. Respiratory rate increased during handling and correlated with holding time and group size, while heart rate decreased. Packed cell volume was higher in females. Cortisol concentrations differed between restraint groups and sex and inversely correlated with agonistic behavior. The most common behavior was increased vigilance. Sternal recumbency increased over holding time. During handling procedures, frequency of sudden movements like kicking and attempts to stand increased as restraint time increased. Females vocalized more than males. In conclusion, the methods used triggered measurable changes suggestive of short-term stress that appeared to be physiologically tolerated by the vicuñas.

“…Increase of serum cortisol was observed in pigs under stress conditions including high temperature and transportation [ 13 ]. Increased cortisol levels lead to increase post-mortem metabolism that could be reflected on meat quality [ 14 ]. Higher serum cortisol was related poor pork quality with a higher muscle temperature [ 15 ], faster muscle pH decline, higher drip loss and lightness in pork [ 16 ].…”

ObjectiveAn experiment was conducted to study the blood haematology, muscle pH, and serum cortisol changes in pigs with different levels of drip loss.MethodsTwo groups (low and high) of 20 animals were selected from 100 pigs based on drip loss. All [Duroc× (Large White×Landrace)] pigs were slaughtered according to standard slaughtering procedures. At exsanguinations, blood samples were taken for the haematological parameters and serum cortisol analysis. The muscle samples were taken from longissimus dorsi muscle to evaluate the muscle pH and drip loss.ResultsHaematological parameters of low drip loss group showed higher content of white blood cells and monocytes than high drip loss group (p<0.05). The low drip loss group had higher muscle pH at 45 min (p<0.05) and 24 h (p<0.001) post-mortem than the high drip loss group. However, there was no significant difference in serum cortisol levels (p>0.05).ConclusionDrip loss is mainly affected by the muscle pH decline after slaughter and also might be affected by white blood cells and monocytes.
