Holstein calves (n = 45) were used to evaluate the effects of the addition of vitamin E (0, 100 or 1000 IU) to colostrum on absorption of α‐tocopherol and immunoglobulin in neonatal calves. Colostrum (2 l) was fed to calves as soon as possible aft

In early weaned calves, rumen development resulting in elevated concentrations of blood β‐hydroxybutyrate (BHBA), or stress resulting in elevated concentrations of blood cortisol, may be deleterious to cell‐mediated immunity and overall calf hea
