This study sought to evaluate the effects of receiving magnetized water on reproductive performance, blood constituents, antioxidant capacity and immunity of rabbit bucks. Sexually mature NZW bucks were (n=30) were allotted into 3 groups (10/group).  Bucks in the first group received natural drinking water (NW, G1), while bucks in the second and third groups were received magnetic water (MW, 1500 and 3000 Gauss) for 30 days pre-semen collection, respectively. Semen was collected twice/week for 2 months. Reaction time (RT), and blood constituents, testosterone, antioxidants and immunity status were determined at the last collection week. Semen was evaluated and sperm outputs/ejaculate were calculated. Results showed the RT reduced (P<0.05) and testosterone increased (P<0.05) in MW groups. Red blood cells and packed cell volume, percentage of neutrophils and eosinophils, total proteins, albumin, globulin, high density lipoproteins, total antioxidant capacity and antibody titer increased, while white blood cells and percentages of lymphocytes, monocytes and acidophils, urea, creatinine, total lipids, triglycerides, total cholesterol, low density lipoproteins, malondialdehyde and lysozyme decreased (P<0.05) in MW groups. Treatment of MW improved (P<0.05) semen quality, litter size at birth and at weaning, bunny and litter weights at birth and at weaning. In conclusion, magnetizing water with 1500 Gauss for drinking rabbit bucks (30 days pre-semen collection) lead to significant improvement in water characteristics and antioxidant capacity, immunity, semen quality and fertility of rabbit bucks.
