Resumo: The present study was carried out between September and October 2020, in Santana do Livramento, Rio Grande do Sul. The experiment aimed to evaluate the reproductive activity of dairy sheep outside the conventional breeding season. Seventeen multiparous Lacaune ewes were used. The hormonal protocol used consisted of the intravaginal implant for a period of seven days of the progesterone hormone, added to the intramuscular injection of equine chorionic Gonadotropin (eCG) at the time of implant removal, at a dose of 400 IU. After treatment the animals were subjected to a period of mating for 5 days. The estrus was recorded with the help of sheep marked with ink on the chest. The sheep presented 52.9% (9/17) of estrus expression rate. The results obtained demonstrate that the hormonal treatment in dairy sheep allows the manifestation of estrus in periods of the year when it would not naturally occur.

El experimento tuvo como objetivo evaluar la actividad reproductiva de las ovejas lecheras fuera de la temporada de cría convencional. Se utilizaron 17 ovejas Lacaune multíparas. El protocolo hormonal utilizado consistió en el implante intravaginal por un período de siete días de la hormona progesterona, más la inyección intramuscular de Gonadotropina Coriónica Equina (eCG) al momento de la extracción del implante, a una dosis de 400 UI. Después del tratamiento, los animales se sometieron a un período de encarnación durante 5 días. El calor se registró con la ayuda de ovejas marcadas con tinta en el pecho. Las ovejas presentaron 52,9% (9/17) de tasa de expresión de estro. Los resultados obtenidos demuestran que el tratamiento hormonal en ovinos lecheros permite la manifestación del celo en épocas del año en que no ocurriría de forma natural.O presente estudo foi realizado entre setembro e outubro de 2020, em Santana do Livramento, Rio Grande do Sul. O experimento objetivou avaliar a atividade reprodutiva de ovelhas leiteiras fora da estação convencional de acasalamento. Foram utilizadas 17 ovelhas multíparas da raça Lacaune. O protocolo hormonal utilizado consistiu no implante intravaginal por um período de sete dias do hormônio progesterona, somado a injeção intramuscular de Gonadotrofina coriônica equina (eCG) no momento da retirada do implante, na dose de 400 UI. Após o tratamento os animais foram submetidos a um período de encarneiramento por 5 dias. Registrou-se o momento do cio com auxílio de carneiros marcados com tinta no peito. As ovelhas apresentaram 52,9% (9/17) de taxa de expressão de cio. Os resultados obtidos demonstram que o tratamento hormonal em ovelhas leiteiras possibilita a manifestação de cio em períodos do ano em que naturalmente não ocorreria.Research, Society and Development2021-12-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/1436310.33448/rsd-v10i16.14363Research, Society and Development; Vol. 10 No. 16; e46101614363Research, Society and Development; Vol. 10 Núm. 16; e46101614363Research, Society and Development; v. 10 n. 16; e461016143632525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/14363/20703Copyright (c) 2021 Karoline Barcellos da Rosa; Rodrigo Flores Escobar; Rivas Matheus Lencina dos Santos; Tayã de Menezes Furtado Guedes; Gianny de Mello Maydana; Thais Moreira Osório; Leonardo de Melo Menezeshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessRosa, Karoline Barcellos da Escobar, Rodrigo Flores Santos, Rivas Matheus Lencina dos Guedes, Tayã de Menezes Furtado Maydana, Gianny de Mello Osório, Thais Moreira Menezes, Leonardo de Melo 2021-12-20T11:03:07Zoai:ojs.pkp.sfu.ca:article/14363Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:35:31.043829Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
