Abstract
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 with no free access to outdoor runs or indoors with free access to outdoor runs) on stress levels and slaughter value in growing-finishing pigs.
