Resumo: Fertility is the most important factor in determining profitability of beef herd. Deficiency of vitamins and other essential nutrients can impact bull reproduction components. The aim of this study was to evaluate the reproductive characteristics of pre-pubertal bulls supplemented with vitamin A. Forty Nellore bulls aged between 18 and 20 months were used. They were allocated into two groups: treated, which received vitamin A (2 ml/animal); and control, which were not supplemented. The animals went through andrological examination. Orchiectomy was performed for histopathological evaluation of the testis. Mean motility and sperm vigor were higher in the animals present in the treated group (p <0,01). No differences were found between the groups in the other andrological parameters evaluated. The structures analyzed in the histopathological examination presented normal appearance. The data suggest that Vitamin A supplementation can have positive results on sperm quality of pre-puberty bulls.

La deficiencia de vitaminas y otros nutrientes esenciales puede afectar los componentes reproductivos de los toros. El objetivo de este estudio fue evaluar las características reproductivas de los toros en la fase previa a la pubertad suplementados con vitamina A. Se utilizaron cuarenta toros Nelores, con edades comprendidas entre 18 y 20 meses. Se dividieron en dos grupos: tratados, que recibieron vitamina A (2 ml / animal), y control, que no fueron suplementados. Los animales se sometieron a un examen andrológico y a una orquiectomía para la evaluación histopatológica de los testículos. La motilidad promedio y el vigor de los espermatozoides fueron mayores en los animales presentes en el grupo tratado (p <0.01). No se encontraron diferencias entre los grupos en los otros parámetros andrológicos evaluados. Las estructuras analizadas en el examen histopatológico mostraron una apariencia normal. Los datos sugieren que la suplementación con vitamina A puede tener resultados positivos en la calidad del esperma de los toros antes de la pubertad.A fertilidade é o fator mais importante na determinação da rentabilidade em rebanhos bovinos. Deficiência de vitaminas e outros nutrientes essenciais podem afetar componentes reprodutivos de touros. O objetivo deste estudo foi avaliar as características reprodutivas de touros na fase pré-pubere suplementados com vitamina A. Foram utilizados quarenta touros Nelores, com idade entre 18 e 20 meses. Eles foram divididos em dois grupos: tratados, que receberam vitamina A (2 ml / animal), e controle, que não foram suplementados. Os animais passaram por exame andrológico e foram submetidos à orquiectomia para avaliação histopatológica do testículo. A média de motilidade e vigor espermático foram maiores nos animais presentes no grupo tratado (p < 0,01). Não foram encontradas diferenças entre os grupos nos demais parâmetros andrológicos avaliados. As estruturas analisadas no exame histopatológico apresentaram aparência normal. Os dados sugerem que a suplementação de vitamina A pode ter resultados positivos na qualidade espermática dos touros pré-puberdade.Research, Society and Development2020-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/335410.33448/rsd-v9i6.3354Research, Society and Development; Vol. 9 No. 6; e174963354Research, Society and Development; Vol. 9 Núm. 6; e174963354Research, Society and Development; v. 9 n. 6; e1749633542525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/3354/3902Copyright (c) 2020 Luís Gustavo Lopes Silva, Mírianny Urzeda, Mírianny Urzeda, Mírianny Urzeda, Mírianny Urzeda, Mírianny Urzeda, Gabriel Moreira Ramos, Gabriel Moreira Ramos, Adriana da Silva Santos, Wesley José de Souza, Wesley José de Souza, Gabriel Moreira Ramos, Wesley José de Souza, Gabriel Moreira Ramos, Rodrigo Diniz de Castro, Wesley José de Souza, Wesley José de Souza, Wesley José de Souza, Igor Ribeiro, Mírianny Urzeda, Adriana da Silva Santos, Rodrigo Diniz de Castro, Rodrigo Diniz de Castro, Rodrigo Diniz de Castro, Igor Ribeiro, Igor Ribeiro, Igor Ribeiro, Igor Ribeiro, Rodrigo Diniz de Castro, Adriana da Silva Santos, Adriana da Silva Santos, Rodrigo Diniz de Castro, Adriana da Silva Santos, Adriana da Silva Santos, Gabriel Moreira Ramos, Gabriel Moreira Ramos, Igor Ribeiroinfo:eu-repo/semantics/openAccessSilva, Luís Gustavo LopesUrzeda, MíriannyRamos, Gabriel MoreiraCastro, Rodrigo Diniz deRibeiro, IgorSantos, Adriana da SilvaSouza, Wesley José de2020-08-20T18:05:46Zoai:ojs.pkp.sfu.ca:article/3354Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:27:34.738741Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
