Abstract. Usually, in birds, as in all warm-blooded animals, homeostasis is understood as a combination of internal processes involving hormones, the endocrine system and metabolism. In order forquails raised in warm temperature conditions (summer months) to not fall into thermostress, biomarkers should be used to make timely diagnoses. In order to clarify the stress caused by temperature stress in breeding (mother) quails during the study period, we aimed to use the hormone cortisol as a biomarker. During the study, in order to examine the homeostasis indicators (physiological and biochemical) of temperature stress in all groups, the internal body temperature of the quails, the amount of cortisol, glucose, and hematological markers were first determined.
The results showed that good results for quails were obtained during the period of maintaining air exchange at 4.5 m3/h. Our research showed that the cortisol hormone can be used as a biomarker for timely and accurate determination of stress in quails during hot summer days.
