Effect of DUR by day (P < 0.01) relative to transit event (day 0) on (a) serum non-esterified fatty acid (NEFA), (b) lactate, and (c) haptoglobin (HP) concentrations based upon repeated measures analysis of samples collected on days −5 and 1 (post-transit), days 2 and 3 (24 and 48 h post-transit, respectively), and day 7. Within a panel, values with unlike superscripts differ (P ≤ 0.05). 8-h = steers transported for 8 h (727 km) and 18-h = steers transported for 18 h (1,770 km). There was no effect of INJ, INJ × Day, or INJ × DUR × Day (P ≥ 0.17). N = 18 steers per DUR treatment.
