Resumo: Selenium and vitamin E are important antioxidants for cells and tissues protection acting directly as a support for the udder health. This experiment was designed to evaluate the influence of prepartum selenium and vitamin E supplementation on milk somatic cell counts of Holstein cows during summer period. Eighty animals were allocated into four treatments: control; supplementation with 2.5 mg Se/day; supplementation with 1000 IU vitamin E/day and supplementation with 2.5 mg Se/day + 1000 IU vitamin E/day. The supplementation started thirty days prior to probable parturition date until parturition. Forage and concentrate samples were taken every fifteen days for chemical and selenium analyses. Blood samples were taken before starting supplementation, right after parturition, thirty and sixty days after it to determine the selenium serum levels. Milk samples were taken to determine SCC. Selenium supplemented cows had higher serum selenium concentration compared with control group (P;0.05) SCC up to 12th week of lactation.

O presente trabalho teve como objetivo avaliar o efeito do selênio e da vitamina E sobre a contagem de células somáticas no leite de vacas da raça holandesa, durante o período das águas. Oitenta animais foram distribuídos em quatro tratamentos: controle; suplementação com 2,5 mg Se/dia; suplementação com 1000 UI vit. E/dia e suplementação com 2,5 mg Se + 1000 UI vit. E/dia. 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 Se no soro sangüíneo das vacas. O leite foi colhido semanalmente, para determinação da contagem de células somáticas (CCS). O período de colheita iniciou-se logo após o período colostral, prolongando-se até a décima segunda semana de lactação. Um mês após a suplementação, as vacas que receberam selênio apresentaram níveis séricos superiores (P;0,05) a CCS nas doze primeiras semanas de lactação e não foi encontrado efeito de interação entre os dois elementos.Universidade de São Paulo.
