Seasonal variations in plasma glucocorticoid levels in yaks (Poephagus grunniens L.) (Bos grunniens).
The changes of glucocorticoid concentrations were measured by highly sensitive enzymeimmunoassay procedures using second antibody coating technique and cortisol -HRP amplified system for one whole calendar year in yaks. The year was divided into seasons of cool, intermediate and hot seasons. The glucocorticoid values were lower (P < .01) in hotter months than in cool and intermediate seasons. Rectal temperature and respiration rates were indicative of heat stress in the hot temperature season and gave significant negative correlation with circulating corticoid concentration.
