Efeito da suplementação de selenometionina e vitamina C sobre a morfopatologia espermática do sêmen de coelho = Effect of selenomethionine and vitamin C supplementation on spermatic morphopathology in the rabbit semen

Abstract

Foi avaliada a morfopatologia espermática do sêmen de coelhos alimentados com rações contendo diferentes níveis de selenometionina (SeM) e vitamina C (VC). Utilizaramse 125 coelhos, alojados individualmente, e distribuídos em um delineamento experimentalinteiramente casualizado, com vinte e cinco tratamentos e cinco repetições. Avaliaram-se a normalidade espermática (NO), patologias totais (PT), patologias primárias (PP) e patologias secundárias (PS). Observou-se influência dos tratamentos com SeM e VC (PThe 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.
