micronutrients, and cortisol concentrations were measured in 43
clinically healthy postparturient Holstein cows. Estimated
305-day mature equivalent milk production and neutrophil
function were related to results of the blood micronutrient
concentrations and neutrophil function tests. Cattle had low to
normal zinc concentrations; normal to high selenium, vitamin E,
and cortisol concentrations; and normal copper concentrations.
Blood selenium (P = .03) and zinc (P = .027) concentrations were
both significant predictors of neutrophil adhesion, and selenium
(P < .001) was a significant predictor of neutrophil cytochrome
