Summary This study aimed to evaluate the effect of heat stress ( HS ) and selenium supplementation on markers stress, meat quality gene expression. For this, quails 42 days age were fed a diet that either met [0.33 mg/kg, nutritional demand for SS )] or did not meet [0.11 deficient SD demands during 7 evaluation. In addition, animals kept at thermal comfort temperature (25 °C) exposed (38 °C 24 h). Glutathione synthetase GSS ), glutathione reductase GSR uncoupling protein UCP expression influenced by interaction between diet. Animals subjected exhibited highest terms expression, lowest values observed in peroxidase GPX body BT creatine kinase CK activity both . Aspartate aminotransferase AST alanine ALT creatinine content all diet/environment interaction. The activity, levels also an increased heterophil/lymphocyte ratio lower triiodothyronine (T3) hormone than birds remained comfortable temperature. with supplemented showed better results regarding and, thus, activities enzymes used as markers, which could be due higher antioxidant capacity provided action studied genes.
