Over the entire trial (56 days), ADG increased linearly as a result of gain:feed increasing linearly as chromium concentrations were increased, with 0.3 mg/kg of chromium being the most favorable treatment level. The highest chromium dose (0.3 mg/kg) tended to improve efficiency when compared directly to the control steers; this created a 10.8% increase in ADG in
favor of the 0.3 mg/kg chromiumsupplemented steers, as shown in Table 2 (Bernhard et al., 2012)
