Abstract
ABSTRACT Cortisol is a steroid hormone, one of the glucocorticoids, made in the cortex of the adrenal glands and then released into the blood, which transports it in the entire body. Almost every cell contains receptors for cortisol and so cortisol can have lots of different actions depending on which sort of cells it is acting upon. These effects include controlling the body’s blood sugar levels and thus regulating metabolism, acting as an anti-inflammatory product, controlling salt and water balance and influencing blood pressure. The study was conducted over a period of 3 months, between March-August 2020, in 2 swine farms in Iasi county, Romania, on a total of 46 pigs, 3 to 4 months old, both males and females, in order to investigate stress levels in finishing facilities. The study revealed higher levels of cortisol while eosinophil counts severely decreased, changes which are associated with a strong reaction to stress for individuals that were housed in finishing facilities.
Highlights
Cortisol is a steroid hormone that regulates a wide range of vital processes throughout the body, including metabolism and the immune response
The adrenocorticotropic hormone levels start to drop, which leads to a drop in cortisol levels, the regulation of cortisol being made by the means of a negative feedback loop (Etim et al, 2013)
Cortisol is produced from cholesterol in the two adrenal glands located on top of each kidney
Summary
Cortisol is a steroid hormone that regulates a wide range of vital processes throughout the body, including metabolism and the immune response. It has a very important role in helping the body respond to stress. Almost every cell contains receptors for cortisol and so cortisol can have lots of different actions depending on which sort of cells it is acting upon These effects include controlling the body’s blood sugar levels and regulating metabolism, acting as an anti-. When cortisol levels in the blood are low, the hypothalamus releases corticotrophin-releasing hormone, which causes the pituitary gland to secrete adrenocorticotropic hormone into the bloodstream. The adrenocorticotropic hormone levels start to drop, which leads to a drop in cortisol levels, the regulation of cortisol being made by the means of a negative feedback loop (Etim et al, 2013)
