Calcidol is a metabolite of vitamin D metabolism. It can be used to prevent and treat vitamin D deficiency. The objective of this study was to evaluate the effects on feed intake, growth performance, and health when calcidol [25(OH)D3] or a combination of calcidol and beta-carotene (precursor to Vitamin A) was supplemented in high-risk, newly received growing beef heifers.
