Abstract

This aims to study of effect of dietary by selenium and vitamin E on body weight and reproductive performance in rabbet. A total of 80 male rabbits at two months age and average of initial live body weight was 2.27 kg. Animals were separately housed in wire-cages, The light-dark period was controlled to be 16 h of light and 8 h of darkness. The animals were randomly assigned to the following: four experimental treatments (n=20 each): T1: Control group that fed basal diet, T2: Fed basal diet + 0.1 mg organic Se / kg diet, T3: Fed basal diet + 40 mg α-tocopherol acetate / kg diet and T4: Fed basal diet + 40 mg α-tocopherol acetate / kg diet + 0.1 mg organic Se/kg diet, The diet contains 18% protein, 2850 kcal. These measurements were recorded body weight, semen collection and evaluation, ejaculate volume, mass motility, percentage of progressive sperm motility, percentage of dead sperm (%), percentage of abnormal spermatozoa (%), acrosomal damages, hypo-osmotic swelling (HOS-test) reacted spermatozoa (%), and testosterone hormone concentration. The results can be summarized the changes of averages body weight were not significantly among treatment. While means of ejaculate volume, the percentage of mass motility, acrosome damages, progressive motility, and testosterone levels, were highest significantly (P˂0.05). The percentage of dead sperms, percentage of abnormalities, HOS-test, was lowest significantly in treatment group. From this study, recommended to add selenium and vitamin E to the diet of rabbits.
