Amiri Andi M, Fallah F., Effects of selenium and vitamin E administration to pregnant cows on IgG, colostrum and weight of newborn calves, Onl J Vet Res., 19(11): 769-775, 2015., Three groups of 20 pregnant Holstein cows each were supplemented or injected 8g vitamin E with or without selenium 21 days before partus. There were significantly (p<0.05) higher IgG colostrum levels in calves born from cows supplemented oral or injectable vitamin E with selenium. Calves born from cows fed oral vitamin E had highest colostrum IgG levels and weaning weights compared with those given other treatments. Treatments had no significant effect f on cows or calves IgG serum levels at 7d age, weight at birth or later. Results suggest that oral vitamin E may have had aneffect on IgG levels in colostrum and weaning weight of calves. Results were not compared with untreated controls and must be evaluated in this context.
