Topic:Cortisol
Cortisol is a steroid hormone produced by the adrenal glands in horses, playing a significant role in the regulation of metabolism, immune response, and stress management. As a glucocorticoid, cortisol influences various physiological processes, including glucose metabolism, inflammation modulation, and the maintenance of homeostasis during stress. Its levels in horses can vary due to factors such as exercise, environmental changes, and psychological stressors. Cortisol is often measured to assess stress responses and overall well-being in equine health management. This page compiles peer-reviewed research studies and scholarly articles that explore the production, regulation, and implications of cortisol in equine physiology and health.
Plasma concentrations of cortisol and corticosterone in the normal horse. The plasma concentration of cortisol and corticosterone in the normal horse was determined by competitive protein-binding analysis (radiostereoassay). The mean plasma concentration of the 2 steroids in resting horses was 5.12 μg./ml., with standard deviation of 1.67 μg. There were no significant differences in the mean values according to age, sex, and pregnancy. Seemingly, diurnal variations in concentrations of the steroids existed in horses; values were high in the morning and low in the evening. Plasma values were increased in horses given corticotropin (acth) and were decreased in those...

Metabolism before, during and after anaesthesia in colic and healthy horses. Many colic horses are compromised due to the disease state and from hours of starvation and sometimes long trailer rides. This could influence their muscle energy reserves and affect the horses' ability to recover. The principal aim was to follow metabolic parameter before, during, and up to 7 days after anaesthesia in healthy horses and in horses undergoing abdominal surgery due to colic. Methods: 20 healthy horses given anaesthesia alone and 20 colic horses subjected to emergency abdominal surgery were anaesthetised for a mean of 228 minutes and 183 minutes respectively. Blood for analysis o...
