Heat stress poses significant challenges for rabbit production, affecting welfare, growth, and overall performance. In this study, we aimed to evaluate the impact of dietary supplementation with thymol, eugenol, and their combination on the growth parameters and hematological parameters on growing heat stressed rabbits. Sixty weaned V-line rabbits, aged 35 days with an initial body weight of 654 ± 10 g were distributed into five groups: C- (control diet under thermoneutral conditions), C+ (control diet under heat stress), T (250 mg/kg thymol supplemented with the control diet under heat stress), E (250 mg/kg eugenol supplemented with the control diet under heat stress), and ET (250 mg/kg thymol + 250 mg/kg eugenol supplemented with the control diet under heat stress).The results revealed that both the thymol alone and thymol-eugenol mixture in rabbits' diet contributed to the highest body weight and weight gain, showing significant improvements during specific weeks of the trial due to their phytogenic substances properties (P
