Figure 2. — Effect of injectable vitamin C (VC) treatment and time of sampling relative to weaning on day 0 on plasma ascorbate concentrations in early-weaned (65 ± 11 d of age) beef steers. Treatments were applied at weaning (WEAN) on day 0 including intramuscular injections (20 mL per steer) of VC (250-mg sodium ascorbate per mL; 5 g per steer) or saline (SAL; 20 mL per steer). Samples were collected on day 0 at 0 h (time of weaning and prior to treatment injection), 24 h (day 1), 48 h (day 2) postinjection. Day 0 plasma ascorbate concentration was used as a covariate. Means were separated across all time points and values with unlike superscripts differ (P ≤ 0.05). Effects of WEAN × time (P < 0.01), WEAN (P < 0.01), and time (P < 0.01) were observed. N = 24 steers per treatment.
