The relationship between milk somatic cells count (SCC) and milk yield has been the aim of countless researches in several countries; however, in Brazil, the literature related to this subject is scarce. Therefore, the objective of this study is to verify if the losses in milk yield due to SCC increase are proportional to the yield, or absolute (independent of it) and starting from which SCC, the losses become evident. For this study, 13.725 observations were used, collected monthly from […]

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. Eighty four animals were allocated into four treatments: control; supplementation with 5 mg Se/day; supplementation with 1000 UI vitamin E/day and supplementation with 5 mg Se/day + 1000 UI vitamin E/day. The supplementation started thirty days […]
