Resumo: The aim of this work was to evaluate the effect of selenium and vitamin E on incidence of mastitis in Holstein cows. Eighty cows were allocated into four treatments: control, supplementation with 2.5 mg Se day-1, supplementation with 1,000 UI vitamin E day-1, and supplementation with 2.5 mg Se day-1 + 1,000 UI vitamin E day-1. The supplementation started 30 days prior to probable parturition date until parturition. Forage and concentrate samples were taken every 15 days for chemical and selenium analyses. Blood samples were taken before starting supplementation, right after parturition, 30 and 60 days after it to determine the selenium serum levels. Tamis test and udder analysis were weekly performed to detect clinical mastitis. Selenium supplemented cows had higher serum selenium concentration compared with control group (P < 0.05). Vitamin E and selenium did not decrease the prevalence of clinical mastitis up to 12th week and there was no interaction between those elements.

Oitenta vacas foram distribuídas em quatro tratamentos: controle e suplementação com 2,5 mg selênio dia-1, com 1.000 UI vitamina E dia-1 e com 2,5 mg selênio + 1.000 UI vitamina E dia-1. A suplementação foi iniciada 30 dias antes da provável data de parição, prolongando-se até o parto. Amostras do volumoso e do concentrado foram colhidas, quinzenalmente, para análise bromatológica completa e levantamento dos níveis de selênio. O sangue foi colhido antes do início da suplementação, no parto, 30 e 60 dias após o parto, para determinação dos níveis de selênio. O teste de Tamis e a análise clínica do úbere foram realizados semanalmente, para detecção de mastite até a décima segunda semana de lactação. Um mês após a suplementação, as vacas que receberam selênio apresentaram níveis séricos superiores (p < 0,05) ao grupo controle. A vitamina E e o selênio não afetaram a prevalência de mastite clínica, nas doze primeiras semanas de lactação, e não foi encontrada interação entre os dois elementos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraPaschoal, Juliana JorgeZanetti, Marcus AntonioCunha, José Aparecido2005-10-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7062Pesquisa Agropecuaria Brasileira; v.40, n.10, out. 2005; 1043-1046Pesquisa Agropecuária Brasileira; v.40, n.10, out. 2005; 1043-10461678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7062/4110info:eu-repo/semantics/openAccess2010-09-08T12:34:08Zoai:ojs.seer.sct.embrapa.br:article/7062Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-09-08T12:34:08Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
