In recent years, medical and aromatic herbs have been used in rabbits' production to replace antibiotic and have increasingly important role. A total of 40 weaned V-line rabbit bucks were divided equally into four experimental groups. The bucks of the 1^st group not treated and served as the control group, while those in the 2^nd, 3^rd and 4^th groups were oral supplementation with mixture dried herbal seeds at level of 200 ,400 and 600mg /buck/day, respectively. The obtained results revealed significant (P≤0.05) increase in BW, BWG and FCR of the treated bucks than those of the control. However, results of total feed consumption showed insignificant differences. The averages of total protein, globulin, albumin and glucose (mg/dl) of treated groups increased significantly (P≤0.05) as compared with the control group. While the means of triglyceride and cholesterol decreased significantly (P≤0.05) in the treated bucks than those of the control group. The averages of live sperm, (%), Mass motility, (%), concentration (10⁶/ml) and ejaculate volume (ml) of the treated bucks increased significantly (P≤0.05) than those of the control, while the reaction time (seconds) and abnormal sperm, (%) decreased significantly (P≤0.05) in the treated bucks than those of the control group. In conclusion, this study demonstrated that treating rabbit bucks raised under Assiut climatic conditions with a mixture of some dried herbal seeds at level of (200,400 and 600/buck/day) significantly improved growth performance, blood parameters and semen quality.
