Resumo: This study aimed to evaluate the association of Doppler ultrasound with clinical andrological examination to identify the reproductive quality of stallions in paraiban swamp region. Eleven horses were used, aged between three and 27 years. The ejaculates were collected by the artificial vagina method and the seminal samples were submitted to field evaluation (subjective motility, cellular integrity) and in the laboratory (objective motility, cellular integrity). After seminal collection, the animals were submitted to testicular blood flow evaluation with Doppler ultrasound. Differences (P<0.05) were observed between the parameters of subjective motility, field-evaluated, and objective motility, in the laboratory. The integrity of the sperm plasma membrane was similar in field and laboratory tests. In the ultrasound parameters, it was observed that the Pulsatility Index has a positive correlation with lateral head displacement amplitude (ALH) of the spermatozoa. Finally, when evaluating age parameter, elderly animals presented reduced motility and lower blood supply in the testicular region, resulting in low fertility. It is concluded that the clinical andrological examination, when isolated, does not determine the fertile capacity of stallions; doppler-associated ultrasound identifies subfertile animals and can be an auxiliary tool in the stallions selection.

Se utilizaron once caballos, con edades comprendidas entre los tres y los 27 años. Los eyaculados fueron recolectados por el método de vagina artificial y las muestras seminales fueron sometidas a evaluación de campo (motilidad subjetiva, integridad celular) y en el laboratorio (motilidad objetiva, integridad celular). Después de la recolección seminal, los animales se sometieron a evaluación del flujo sanguíneo testicular con ultrasonido Doppler. Se observaron diferencias (P <0.05) entre los parámetros de motilidad subjetiva, evaluados en campo y motilidad objetiva, en el laboratorio. La integridad de la membrana plasmática de los espermatozoides fue similar en las pruebas de campo y de laboratorio. En los parámetros eco-gráficos, se observó que el Índice de Pulsatilidad tiene una correlación positiva con la amplitud de desplazamiento lateral de la cabeza (ALH) de los espermatozoides. Finalmente, al evaluar el parámetro de edad, los animales de edad avanzada presentaron menor motilidad y menor riego sanguíneo en la región testicular, resultando en baja fertilidad. Se concluye que el examen clínico andrológico, cuando se aísla, no determina la capacidad fértil de los sementales; La eco-grafía asociada a Doppler identifica animales subfertiles y puede ser una herramienta auxiliar en la selección de sementales.Objetivou-se avaliar a associação da ultrassonografia Doppler com o exame clínico andrológico para identificação da qualidade reprodutiva de equinos no Brejo paraibano. Foram utilizados 11 equinos da raça Quarto de milha, com idade entre três a 27 anos. Os ejaculados foram colhidos pelo método de vagina artificial e as amostras seminais submetidas à avaliação a campo (motilidade subjetiva, integridade celular) e em laboratório (motilidade objetiva, integridade celular). Após colheita seminal, os animais foram submetidos à avaliação do fluxo sanguíneo testicular por ultrassonografia doppler. Diferenças (p<0,05) foram observadas entre os parâmetros de motilidade subjetiva, avaliada a campo, e motilidade objetiva, no laboratório. A integridade da membrana plasmática espermática foi semelhante nos testes a campo e em laboratório. Nos parâmetros ultrassonográficos, observou-se que o Índice de Pulsatilidade tem correlação positiva com amplitude de deslocamento lateral de cabeça (ALH) do espermatozoide. Por fim, com o aumento da idade dos reprodutores, observou-se redução da motilidade e menor aporte sanguíneo na região testicular, resultando em menor potencial de fertilidade. Conclui-se que o exame clínico andrológico, quando isolado, não determina a capacidade fértil de garanhões; a ultrassonografia associada ao método doppler identifica animais subférteis e pode ser uma ferramenta auxiliar na seleção de reprodutores equinos.Research, Society and Development2021-11-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2241210.33448/rsd-v10i14.22412Research, Society and Development; Vol. 10 No. 14; e582101422412Research, Society and Development; Vol. 10 Núm. 14; e582101422412Research, Society and Development; v. 10 n. 14; e5821014224122525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/22412/19903Copyright (c) 2021 Allan Gledson Ferreira dos Santos; Hugo Albino Braz; Robespierre Augusto Joaquim Araújo Silva; Maria Madalena Pessoa Guerra; Marlon de Vasconcelos Azevedo; Sildivane Valcácia Silvahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSantos, Allan Gledson Ferreira dosBraz, Hugo AlbinoSilva, Robespierre Augusto Joaquim Araújo Guerra, Maria Madalena PessoaAzevedo, Marlon de VasconcelosSilva, Sildivane Valcácia2021-12-04T11:48:39Zoai:ojs.pkp.sfu.ca:article/22412Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:41:35.108832Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
