Effect of injectable vitamin C (VC) treatment and time of sampling relative to a 6-h transit event on day 49 on plasma ascorbate concentrations in early-weaned (65 ± 11 d of age) beef steers. Treatments were applied immediately prior to transit (TRANS) on day 49 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 49 at hours 0 (pretransit), 6 (off-truck; day 49), and 24 and 48 postinjection (days 50 and 51). Means were separated across all time points and values with unlike superscripts differ (P ≤ 0.05). Effects of TRANS × time (P = 0.04), TRANS (P = 0.01), and time (P < 0.01) were observed. N = 24 steers per treatment.
