Resumo: | There are few studies about transvaginal ultrasound-guided follicle aspiration in equine medicine regarding potential complications to future fertility of aspirated mares. In order to evaluate the effect of follicular aspiration on subsequent fertility in mares, two experiments were conducted. In Experiment I, fifteen Criollo mares were allocated to one of three groups according to the diameter of the aspirated follicle during estrus: 25-29mm (n=4; Group 1); 30-34mm (n=6; Group 2); > 35mm (n=5; Group 3) and control group (n=15; Group 4). In Experiment II, the follicular aspiration was attempted in twenty-five mares during diestrous, when at least four follicles (> 5mm) were seen in the transrectal ultrasonography of both ovaries. All visible follicles, between 4 and 8 mm, were aspirated. Thirty-one mares served as control. In Experiments I and II, the pregnancy rates in the following cycle after aspiration were 75.0% (Group 1), 83.3% (Group 2), 60.0% (Group 3), and 73.3% (Group 4 - Control); and 76.0% in the aspirated diestrous group and 77.4% in the control group (non aspirated), respectively. On both experiments, pregnancy rates were similar (P>0.05) in treated and control mares. The results of this study show that the conception rates of the first estrus period following follicular aspiration are not affected by the procedure.KEYWORDS: equine, fertility, follicular aspiration, mares. |

Há poucos estudos sobre aspiração folicular transvaginal guiada por ultrassom na medicina equina abordando complicações futuras na fertilidade das éguas aspiradas. Com o objetivo de avaliar o efeito da aspiração folicular na fertilidade das éguas, foram conduzidos dois experimentos. No experimento I, 15 éguas da raça Crioula foram distribuídas em três grupos de acordo com o diâmetro do folículo aspirado durante o estro: 25-29mm (n=4; grupo 1); 30-34mm (n=6; grupo 2); > 35mm (n=5; grupo 3) e grupo controle (n=15; grupo 4). No experimento II, a aspiração folicular foi realizada em 25 éguas durante o diestro quando pelo menos 4 folículos (>5mm) foram observados na ultrassonografia transretal em ambos os ovários. Foram aspirados todos os folículos visíveis, entre 4 e 8 mm. Trinta e uma éguas serviram como controle. No experimento I, a taxa de prenhez no ciclo seguinte a aspiração foi de 75% (grupo 1), 83,3% (grupo 2), 60% (grupo 3), e 73,3% (grupo 4). No experimento II foi de 76% no grupo aspirado e 77,4% no grupo controle (não aspirado). Em ambos os experimentos, as taxas de prenhez foram similares (P>0,05). Os resultados mostram que a taxa de concepção no primeiro ciclo após a aspiração folicular não é afetada pelo procedimento.PALAVRAS-CHAVE: Aspiração folicular, éguas, equino, fertilidade.Universidade Federal de Goiás2014-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa científicaAvaliado por paresPesquisa Científicaapplication/pdftext/htmlhttps://revistas.ufg.br/vet/article/view/2639810.5216/cab.v15i3.26398Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 15 No. 3 (2014); 339-343Ciência Animal Brasileira / Brazilian Animal Science; v. 15 n. 3 (2014); 339-3431809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/26398/17086https://revistas.ufg.br/vet/article/view/26398/17087Franco, Vivian Campos LaiaMozzzaquatro, Fabricio DesconsiOliveira, Rodrigo Arruda deDe La Corte, Flavio DesessardsRubin, Mara Iolanda BatistellaSilva, Carlos Antonio Mondinoinfo:eu-repo/semantics/openAccess2014-09-29T12:57:42Zoai:ojs.revistas.ufg.br:article/26398Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2014-09-29T12:57:42Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)false |
