Resumo: | For years, fatty acids have been recommended as a dietary supplement to improve canine hair. For animal reproduction, supplementation with omegas has been used to increase the reproductive efficiency and conception rate, but few studies have been conducted in dogs. The aim of this study was to evaluate the effects of daily dietary supplementation with omega-3 and -6 on the quality of fresh and frozen/thawed semen in canines. Semen was collected from seven dogs and evaluated for sperm motility, vigor, concentration, and morphology. The 17-week study included 119 ejaculates and was divided according to oral supplementation with omega-3 and -6: M1 (1st-5th week) or pre-supplementation; M2 (6th-9th week) and M3 (10th-13th week) or during supplementation; and M4 (14th-17th week) or post-supplementation. After analysis, the semen was frozen and then revaluated both immediately and 30 minutes (at 37° C) after thawing. Supplementation with omegas increased sperm motility, vigor, and concentration; however, supplementation had no influence on semen freezability. In addition, there was no improvement in sperm motility after supplementation when the thawed cells were maintained at 37° C for 30 minutes. We concluded that dietary supplementation with omega-3 and -6 for 4 to 8 weeks can improve the quality of fresh semen, although it has no effect on the freezability of canine semen. |

Na área de reprodução animal, a suplementação com ômega tem sido usada para aumentar a eficiência reprodutiva e a taxa de concepção em muitas espécies, mas poucos estudos foram conduzidos em cães. Então, o objetivo deste estudo foi avaliar os efeitos da suplementação dietética diária com ômega-3 e -6 sobre a qualidade do sêmen fresco e congelado de cães. Os ejaculados foram colhidos de 7 cães e avaliados quanto a motilidade espermática, vigor, concentração e morfologia. O estudo foi dividido de acordo com os períodos de suplementação oral com omegas-3 e -6, no qual M1 (1ª-5ª semana) foi considerado o período pré-suplementação, M2 (6ª-9ª semana) e M3 (10ª-13ª semana) período de suplementação e M4 (14ª-17ª semana) pós-suplementação, totalizando 17 semanas de estudo (119 ejaculados). Após a análise, o sêmen foi congelado e reavaliado imediatamente e 30 minutos após a descongelação (mantidas a 37º C). A suplementação resultou em aumento da motilidade espermática, vigor e concentração do sêmen fresco; no entanto, não houve influência na congelabilidade do sêmen. Além disso, não houve aumento da motilidade dos espermatozoides após a suplementação, quando as células descongeladas foram mantidas a 37° C, durante 30 minutos. Concluiu-se que a suplementação dietética com omegas-3 e -6, durante 4 a 8 semanas melhora os parâmetros do sêmen fresco de cães, embora não há nenhum efeito sobre a qualidade espermática após a congelação.UEL2017-10-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2587110.5433/1679-0359.2017v38n5p3069Semina: Ciências Agrárias; Vol. 38 No. 5 (2017); 3069-3076Semina: Ciências Agrárias; v. 38 n. 5 (2017); 3069-30761679-03591676-546Xreponame:Semina.
