Resumo: | The aim of this study evaluated the influence of thermal stress on the superovulatory response and on the biochemical profile of superpervulated Dorper ewes in a semi-arid tropical environment. 13 Dorper sheep were used, which were submitted to estrus synchronization and superovulatory treatment, in two different periods [thermoneutral (TN) and thermal stress (ET)]. The sheep were inseminated by laparoscopy using frozen semen 42-43 hours after removal of the intravaginal device. Five days after artificial insemination, laparotomy was performed to assess the ovarian response and uterine lavage. Blood was collected to assess variations in serum concentrations of glucose, fructosamine, triglycerides, β-hydroxybutyrate (BHB), creatinine, urea, total protein, albumin, AST / TGO, GGT, Alkaline Phosphatase, Calcium, Phosphate and Magnesium. The thermoneutral (TN) and thermal stress (ET) periods had average temperatures of 22.01 ° C and 27.61 ° C, respectively, with a relative humidity of 31.9%. There is no difference in ovulatory response and recovery of structures between the TN and ET periods. Concentrations of serum metabolites varied between thermal periods and between assessment times. In conclusion, the thermal period does not affect the efficiency of the superovulation protocol in Dorper ewes reared in a semi-arid tropical environment, but causes changes in serum metabolites. |

Se utilizaron 13 ovejas Dorper, que fueron sometidas a sincronización de celo y tratamiento superovulatorio, en dos periodos diferentes [termoneutral (TN) y estrés térmico (ET)]. Las ovejas fueron inseminadas por laparoscopia usando semen congelado 42-43 horas después de la remoción del dispositivo intravaginal. Cinco días después de la inseminación artificial, se realizó laparotomía para evaluar la respuesta ovárica y el lavado uterino. Se extrajo sangre para evaluar variaciones en las concentraciones séricas de glucosa, fructosamina, triglicéridos, β-hidroxibutirato (BHB), creatinina, urea, proteína total, albúmina, AST / TGO, GGT, fosfatasa alcalina, calcio, fosfato y magnesio. Los períodos termoneutral (TN) y estrés térmico (ET) tuvieron temperaturas promedio de 22.01 ° C y 27.61 ° C, respectivamente, con una humedad relativa de 31.9%. No hay diferencia en la respuesta ovulatoria y la recuperación de estructuras entre los períodos TN y ET. Las concentraciones de metabolitos séricos variaron entre períodos térmicos y entre períodos de evaluación. En conclusión, el período térmico no afecta la eficacia del protocolo de superovulación en ovejas Dorper criadas en un ambiente tropical semiárido, pero provoca cambios en los metabolitos séricos.Este estudo avaliou a influência do estresse térmico na resposta superovulatória e no perfil bioquímico de ovelhas Dorper superovuladas em ambiente tropical semiárido. Foram utilizadas 13 ovelhas da raça Dorper, as quais foram submetidas à sincronização do estro e ao tratamento superovulatório, em dois períodos diferentes [termoneutro (TN) e estresse térmico (ET)]. As ovelhas foram inseminadas por laparoscopia utilizando sêmen congelado 42-43 horas após a remoção do dispositivo intravaginal. Cinco dias após a inseminação artificial, foi realizada laparotomia para avaliação da resposta ovariana e lavagem uterina. Coletou-se sangue para avaliação das variações nas concentrações séricas de glicose, frutosamina, triglicerídeos, β-hidroxibutirato (BHB), creatinina, ureia, proteína total, albumina, AST/TGO, GGT, Fosfatase Alcalina, Cálcio, Fosfato e Magnésio. Os períodos termoneutro (TN) e de estresse térmico (ET) tiveram temperaturas médias de 22,01 °C e 27,61 °C, respectivamente, com umidade relativa de 31,9%. Não houver diferença na resposta ovulatória e recuperação de estruturas entre os períodos TN e ET. As concentrações dos metabólitos séricos sofreram variação entre períodos térmicos e entre momentos de avaliação. Em conclusão, o período térmico não afeta a eficiência do protocolo de superovulação em ovelhas Dorper criadas em ambiente tropical semiárido, mas provoca alterações nos metabólitos séricos.Research, Society and Development2021-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1378010.33448/rsd-v10i4.13780Research, Society and Development; Vol. 10 No. 4; e5710413780Research, Society and Development; Vol. 10 Núm. 4; e5710413780Research, Society and Development; v. 10 n. 4; e57104137802525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/13780/12417Copyright (c) 2021 José Augusto de Souza Bernardo; Edivânia Maria Freitas Bernardo; Robespierre Augusto Joaquim Araújo Silva; Flávio Carneiro da Cunha Mergulhão; Joana Amélia de Senna Costa; Rafael Artur da Silva Júnior; Gustavo Ferrer Carneiro; Pierre de Castro Soares; André Mariano Batistahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBernardo, José Augusto de SouzaBernardo, Edivânia Maria FreitasSilva, Robespierre Augusto Joaquim AraújoMergulhão, Flávio Carneiro da CunhaCosta, Joana Amélia de SennaSilva Júnior, Rafael Artur daCarneiro, Gustavo FerrerSoares, Pierre de CastroBatista, André Mariano2021-04-25T11:21:26Zoai:ojs.pkp.sfu.ca:article/13780Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:02.793157Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
