Effect of repletion strategy (ITM1 vs. BLEND2 vs. ING3) within depletion diet (CON4 vs. ANT5) by day (DEP × REP × day) on plasma Mo concentrations of feedlot steers during the repletion period

1ITM: Injectable trace mineral treatment supplemented inorganic forms of trace minerals at 100% of concentrations recommended by NASEM (2016).
2BLEND: Trace minerals supplemented at 150% of concentrations recommended by NASEM (2016) from 25% organic and 75% inorganic sources.
3ING: Trace minerals supplemented at 150% of concentrations recommended by NASEM (2016) from entirely inorganic sources.
4Control diet contained no supplemental Mo or S.
5Antagonist diet provided supplemental dietary minerals: 2 mg Mo/kg DM, and 0.3% S as CaSO4.
Within a day, superscripts that differ are different (a, b; P ≤ 0.01).
