Abstract
The concentration of 19 mineral, electrolyte and biochemical components in blood serum of 114 calves under feedlot conditions was measured or calculated over a 58 day period (2 days before and 56 days during a feed trial). The variability in the concentration of these components over time was evaluated. The blood was collected on 7 sampling dates and analyzed on the day following samples. The serum concentrations of the components that were measured varied considerably over the first 3 wk of the feeding period and leveled off during the 2nd part of that period.
