E-mail: fvieira.vet@hotmail.com The aim of this study was to determine if the use of Dinoprost Tromethamine during diestrus affected the pregnancy rate in Mangalarga Marchador mares. A retrospective study through analyzing records of 173 Mangalarga Marchador mares totaling 669 estrous cycles. The data were separated into four groups: group I (n = 53 cycles): not submitted to hormonetherapy (control); Group II (n = 86 cycles): cycles submitted induction of ovulation using 1000 IU of hCG; Group III (n = 222 cycles): cycles submitted to oestrus induction with 5.0 mg of Dinoprost Tromethamine; Group IV (n = 308 cycles): estrus cycles induced with 5.0 mg Dinoprost tromethamine and ovulation induced using 1000 IU of hCG. Induction of ovulation occurs when the dominant follicle reached ≥ 35mm diameter. The use of PGF2a was from the seventh day after ovulation. Pregnancy diagnosis was performed 15 days after the ovulation detection in matrix mares. For embryo donors, was considered as a positive result the uterine washed resulting in embryo recovery. Was used the chi-square test (5% significance) and Fisher exact test, when recommended. The pregnancy rate obtained in the group I was 54.71% (29/53) in group II 59.3% (51/86) in group III 49.55% (110/222) and Group IV 59, 41% (183/308). There was no statistical difference (p = 0.132) for the pregnacy rate among the groups. Thus, use of Dinoprost Tromethamine in the seventh day after ovulation did not influence the pregnancy rate. |

Foi realizado estudo retrospectivo através de análise de registros de 173 éguas da raça Mangalarga Marchador, totalizando 669 ciclos estrais. Os dados obtidos foram separados em quatro grupos: grupo I (n = 53 ciclos): ciclos não submetidos à hormonioterapia (controle); grupo II (n=86 ciclos): ciclos submetidos apenas à indu- ção da ovulação utilizando 1000 UI de hCG; grupo III (n = 222 ciclos): ciclos submetidos à indução do estro com 5,0 mg de Dinoprost Trometamina; grupo IV (n = 308 ciclos): ciclos submetidos à indução do estro com 5,0 mg Dinoprost trometamina e indução ovulação utilizando 1000 UI de hCG. A indução da ovulação ocorreu quando o folículo dominante atingiu diâmetro ≥ 35mm. A utilização da PGF2α foi a partir do sétimo dia após a ovulação. O diagnóstico de gestação foi realizado 15 dias após a data da detecção da ovulação em éguas matrizes. Para éguas doadoras de embrião, considerou-se como resultado positivo o lavado uterino que resultou em recuperação embrionária. Foi utilizado o teste Qui-Quadrado (a 5% de significância) e Fisher Exato, quando recomendado. A taxa de gestação obtida no grupo I foi 54,71% (29/53), no grupo II 59,3% (51/86), no grupo III 49,55% (110/222) e no grupo IV 59,41% (183/308). Não houve diferença estatística (p = 0,132) para a taxa de gestação entre os grupos analisados. Sendo assim, utilização de Dinoprost Trometamina a partir do sétimo dia após a ovulação não influenciou a taxa de gestação.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2016-12-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/172Brazilian Journal of Veterinary Medicine; Vol. 38 No. Supl.2 (2016); 164-168Revista Brasileira de Medicina Veterinária; v. 38 n.
