Resumo: The present study evaluated the development of equine conceptus transferred to non-cyclic recipient mares treated with altrenogest. Twenty four mares were used as embryo recipients during the ovulatory phase (Control group; n=8) or anestrus/transitional phases (Altrenogest group; n=16) and were evaluated by transrectal ultrasonography, at five day intervals, to monitor the development of embryonic vesicles from 15 to 45 days of pregnancy and embryo proper/fetus from 20 to 60 days. Embryonic vesicle's features such as shape, embryo location within the vesicle and umbilical cord development were similar between cyclic and non-cyclic recipient mares. The embryonic vesicle and embryo proper/fetus growth was significant (P<0.05) between 15 and 60 days of gestation in Altrenogest and Control groups, except for days 20 to 30, where embryonic vesicle growth decrease was observed (P>0.05). The embryonic vesicle and embryo proper/fetus growth was similar (P>0.05) when gestational days were compared between groups. The similarity in conceptus growth between cyclic and non-cyclic recipient mares during early pregnancy indicates that the uterine environment of non-cyclic recipient mares treated with progestins provides similar conditions for the development of transferred embryos

Vinte e quatro receptoras gestantes por transferência de embrião durante a fase cíclica (grupo Controle; n=8) ou acíclica (grupo Altrenogest; n=16) foram avaliadas por meio de ultrassonografia transretal, a cada cinco dias, para monitorar o desenvolvimento da vesícula embrionária entre 15 e 45 dias de gestação e embrião/feto dos 20 aos 60 dias. As características da vesícula embrionária quanto ao formato, localização do embrião dentro da vesícula e formação do cordão umbilical foram similares em receptoras cíclicas e acíclicas. O crescimento da vesícula embrionária e embrião/feto foi significativo (P<0,05) entre 15 e 60 dias de gestação nos grupos Altrenogest e Controle, com exceção dos dias 20 a 30, em que redução no crescimento da vesícula embrionária foi observada (P>0,05). O crescimento da vesícula embrionária e embrião/feto também foi similar (P>0,05) entre grupos nos diferentes dias de gestação. A similaridade no crescimento do concepto entre éguas receptoras cíclicas e acíclicas durante o início da gestação indica que o ambiente uterino de receptoras acíclicas, mantidas com progestágeno, oferece condições similares para o desenvolvimento de um embrião transferidoFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Universidade Estadual Paulista Departamento de Reprodução Animal e Radiologia Veterinária Faculdade de Medicina Veterinária e ZootecniaUNESP Departamento de Higiene Veterinária e Saúde Pública FMVZUNESP Departamento de Produção Animal FMVZUniversidade Estadual Paulista Departamento de Reprodução Animal e Radiologia Veterinária Faculdade de Medicina Veterinária e ZootecniaUNESP Departamento de Higiene Veterinária e Saúde Pública FMVZUNESP Departamento de Produção Animal FMVZUniversidade Federal de Santa MariaUniversidade Estadual Paulista (Unesp)Silva, Elisa Sant'Anna Monteiro da [UNESP]Pantoja, José Carlos de Figueiredo [UNESP]Puoli, José Nicolau Próspero [UNESP]Meira, Cezinande [UNESP]2015-08-26T19:19:10Z2015-08-26T19:19:10Z2015-03-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/article512-518application/pdfhttp://www.scielo.br/scielo.php?script=sci_arttext&pid=S0103-84782015000300512&lng=en&nrm=iso&tlng=enCiência Rural, v. 45, n. 3, p. 512-518, 2015.0103-8478http://hdl.handle.net/11449/12731610.1590/0103-8478cr20140517S0103-84782015000300512S0103-84782015000300512.pdf00429054157111990000-0002-2245-800XSciELOreponame:Repositório Institucional da UNESPinstname:Universidade Estadual Paulista (UNESP)instacron:UNESPengCiência Rural0.5250,337info:eu-repo/semantics/openAccess2023-11-25T06:15:05Zoai:repositorio.unesp.br:11449/127316Repositório InstitucionalPUBhttp://repositorio.unesp.br/oai/requestopendoar:29462023-11-25T06:15:05Repositório Institucional da UNESP - Universidade Estadual Paulista (UNESP)false
