%X Foi avaliada a morfopatologia esperm¨¢tica do s¨ºmen de coelhos alimentados com ra  es contendo diferentes n¨ªveis de selenometionina (SeM) e vitamina C (VC). Utilizaramse 125 coelhos, alojados individualmente, e distribu¨ªdos em um delineamento experimentalinteiramente casualizado, com vinte e cinco tratamentos e cinco repeti  es. Avaliaram-se a normalidade esperm¨¢tica (NO), patologias totais (PT), patologias prim¨¢rias (PP) e patologias secund¨¢rias (PS). Observou-se influ¨ºncia dos tratamentos com SeM e VC (P<0,05) sobre: PT, PP, PS, cauda dobrada (CD), cauda abaxial (CAB), capuch o solto (CAPS), cabe a raquetiforme (CARE), cauda solta (CAUSO), cauda enrolada na por  o final (CENF), gota citoplasm¨¢tica distal (GODI), gota citoplasm¨¢tica proximal (GOPR), microcefalia (MICRO). O SeM e VC aumentaram (p<0,05) os ¨ªndices de: PT, PP, CD, CAB, CARE, CAUSO, GODIat¨¦ n¨ªveis intermedi¨¢rios e depois voltaram a decrescer. A vitamina C diminuiu o n¨²mero de microcefalias ¨¤ medida que houve o aumento na dieta, demonstrando o efeito de prote  o antioxidante aos espermatoz¨®ides. The spermatic morphopathology in the semen of rabbits, fed with rations containing different selenomethionine (SeM) and vitamin C (VC)levels, were evaluated. 125 male rabbits kept individually in cage were used. They were distributed in a completely randomized design with twenty-five treatments and five replications. The following items were evaluated: sperm normality (SN), total pathologies (TP), primary pathologies (PP) and secondary pathologies (SP). An influence of treatments with SeM and VC (p<0.05) on: TP, PP, SP, bent tail (BT), abaxial tail (AT), free cap (FC), raquetiform head (RH), loose tail (LT), final coiled tail (FCT), distal droplet (DD), proximaldroplet (PD), and microcephalic sperm (MS) was observed. Treatments with SeM and VC increased until an intermediate level and later it reduced the rates of: TP, PP, BT, AT, RH, LT and DD. The microcephalic sperm decreased when vitamin C level was increased,demonstrating the antioxidant protection effect on the spermatozoa.
