Objective: The present study aimed to evaluate the impact of dietary turmeric or garlic extract on physiological responses, hematological parameters, antioxidants status, testicular functions, and health indices of heat-stressed rabbit males. Materials and Methods: Seventy bucks were distributed into seven experimental groups (ten/ group). A commercial diet (CD) was fed to rabbit males in the control group, while males in G2, G3, and G4 were fed CD with turmeric at 30, 60, and 90 mg/kg, respectively. Males in G5, G6, and G7 were fed CD with garlic extract at 50, 75, and 100 mg/kg, respectively, for 8 weeks. Results: The results showed that turmeric or garlic extract levels decreased ear temperature, res¬piration rate, germ cell apoptotic number, total cholesterol, triglycerides, malondialdehyde level, libido, and sperm of dead and abnormal tail (p < 0.05). The hemoglobin and red and white blood cells, platelets, total antioxidants capacity, mass motility, mitochondrial potential, normal, acro¬some reacted, normality, and a total functional fraction of spermatozoa and relative of epididymal weight were increased (p < 0.05). The increased packed cell volume percentage and initial semen fructose were significant only when 100 mg per kg garlic extract was supplemented. Conclusion: Phytochemicals extract supplementation can be an effective dietary supplementation to eliminate heat stress and improve health, oxidative capacity, and testicular functions of rabbit males.
