description	RESUMO: Com o objetivo de verificar os níveis de insulina e cortisol, em folículos ovarianos ovinos de diferentes tamanhos, e suas possíveis correlações com os eventos do ciclo estral desta espécie, o fluido folicular de ovários provenientes de 100 fêmeas mestiças Pantaneiras abatidas foi colhido e avaliado para estes hormônios, por radioimunoensaio, utilizando-se kits comerciais. Os valores obtidos foram analisados por ANOVA e teste de Tukey. A insulina demonstrou diferenças significativas entre os folículos (P&lt;0,000001), à medida em que aumentavam seu diâmetro, enquanto o cortisol manteve-se sem variações significativas em relação ao tamanho folicular (P&gt;0,05). Conclui-se que os folículos ovarianos ovinos possuem concentrações decrescentes de insulina e constantes de cortisol, em relação ao seu tamanho e desenvolvimento.

Follicular fluid of ovine ovaries from 100 crossbred Pantaneiras females was collected and evaluated for hormonal determination by radioimmune test using commercial kits. The values obtained were analyzed by means of ANOVA and Tukey test. Insulin showed significant differences between follicles (P&lt;0.000001), as their diameter increased, while cortisol did not present any significant changes in relation to follicular size (P&gt;0.05). In conclusion, ovine ovarian follicles had decreasing insulin and constant cortisol concentrations, in relation to size and development.Universidad de Caldas2022-03-17T01:14:25Z2025-10-08T21:58:27Z2022-03-17T01:14:25Z2025-10-08T21:58:27Z2022-03-17Artículo de revistahttp://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Textinfo:eu-repo/semantics/articleJournal articlehttp://purl.org/redcol/resource_type/ARTinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85application/pdfhttps://repositorio.ucaldas.edu.co/handle/ucaldas/255872011-5415https://revistasojs.ucaldas.edu.co/index.php/vetzootec/article/view/5628https://revistasojs.ucaldas.edu.co/index.php/vetzootec/article/view/5628spa13293Revista Veterinaria y Zootecnia (On Line)Acosta, T.J.; Tetsuka, M.; Matsui, M.; et al.
