AB  - The objective of this study was to evaluate the effect of dietary Se or Vit. E on semen quality and sperm morphology during fresh and warm seasons in young boars. Four diets (0; 0.5 ppm of Se; 250 IU kg<SUP>-1</SUP> diet of Vit. E; or 0.5 ppm of Se +250 IU kg<SUP>-1</SUP> of Vit. E) were used. Significant effects of season and Vit. E or Se on semen quality and sperm morphology was found. Seminal volume was lower in fresh season (p&lt;0.05). However, sperm concentration, Total Sperm number/Ejaculate (TSE) percentage of normal spermatozoa and motility were higher in fresh season (p&lt;0.05). Spermatic motility, percentage of normal spermatozoa, head abnormalities and retention of cytoplasmic droplets were positively affected (p&lt;0.05) by Se and Vit. E in both seasons. Combination of Se and Vit. E improved sperm concentration in fresh season (p&lt;0.05), while Vit. E solely or combined with Se increased sperm concentration in warm season (p&lt;0.06). Positive effect of Vit. E or combined with Se on TSE was observed in warm season (p&lt;0.05). Reduction of tail abnormalities was observed only during the fresh season in boars fed fortified Se and Vit. E diets (p&lt;0.05). These results suggested that semen quality and sperm morphology can be affected negatively during warm season and Vit. E and Se improve semen quality and strength fertility of boars during the warm season.
