For example, several studies showed that the vitamin E and Se status of cows could affect oxidative stress and have a tremendous impact on the functional capabilities of bovine neutrophils. Supplementing dairy cows with adequate
levels of both vitamin E and Se was shown to increase the phagocytosis, bacterial killing, and oxidative metabolism
of peripheral blood and mammary gland neutrophils when compared to cows that were otherwise deficient in this
micronutrient
