Resumo: The aim of this study was to evaluate the effect of treatment using low doses of EPE on rates of ovulation and embryo recovery. Eight mares were used in this way: first cycle (n = 8) - control group (untreated); second cycle (n = 8) - treated group using 8.0 mg of EPE, bid, until at least two follicles reached ≥35 mm diameter. At this moment, was administered 1000 IU hCG, E.V., as ovulation agent. The embryos recovery were performed eight days after detection of second ovulation. Mares received 5.0 mg PGF2α, I.M. on D8. The percentage of mares that showed two or more ovulations was higher (p <0.01) for the treated group (7/8, 87.5%) than the control group (1/8, 12.5%). The rate of recovered embryos per ovulation did not show statistical difference (P>0.05) between the treated (11/16, 68.8%) and control (6/9, 66.6%)  groups. The results of this study allow concluding that treatment using low doses of EPE increased the incidence of multiple ovulations and provided greater recovery embryos rate.

Foram utilizadas oito éguas da seguinte forma: primeiro ciclo (n=8) - grupo controle (não tratadas); segundo ciclo (n=8) - grupo tratado utilizando 8,0 mg de EPE, bid, até que pelo menos dois folículos atingissem diâmetro ≥35 mm. Neste momento foi administrado 1000 UI, E.V., de hCG como indutor de ovulação. As coletas dos embriões foram realizadas oito dias após detecção da segunda ovulação. As éguas receberam 5,0 mg de PGF2α, I.M. no D8. A porcentagem de éguas com duas ou mais ovulações foi maior (p<0,01) para o grupo tratado (7/8, 87,5%) do que para o grupo controle (1/6, 12,5%). O número de embriões recuperados por ovulação não apresentou diferença estatística (P>0,05) entre os grupos tratado (11/16, 68,8%) e controle (6/9, 66,6%). Os resultados do presente estudo permitem concluir que o tratamento utilizando baixa dose de EPE aumentou significativamente a incidência de múltiplas ovulações e proporcionou maior taxa de recuperação de embriões.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2018-05-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/92210.29374/2525-2179.bjvm034216Brazilian Journal of Veterinary Medicine; Vol. 39 No. 2 (2017); 115 - 119Revista Brasileira de Medicina Veterinária; v. 39 n. 2 (2017); 115 - 1192527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVporhttps://rbmv.org/BJVM/article/view/922/752de Sá, Marcus André FerreiraSantos, Gabriel de OliveiraBezerra, Luciana LimaMoreno, Marcela PoernerBarbosa, Celso GuimarãesAlvarenga, Marco AntônioJacob, Júlio César Ferrazinfo:eu-repo/semantics/openAccess2021-03-12T18:05:54Zoai:ojs.rbmv.org:article/922Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2021-03-12T18:05:54Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false
