The development of healthy, immune competent beef animals during the cow/calf phase of production can be important for successful transition of weaned calves to the feedlot. The objectives of this trial were to determine if differences are present in liver mineral levels, feedlot morbidity and mortality, weaning weights, and serological titers of calves nursing dams supplemented with and having access to one of three mineral supplements: sulfate-based trace minerals, metal-complexed trace minerals, and a control mineral. An additional objective was to determine if differences in liver mineral levels are present in cows fed one of the three minerals on a free choice basis.
