¹Experimental ancillary therapy treatments administered at each antimicrobial treatment for bovine respiratory disease: NOAC = antimicrobial only, no ancillary therapy; NSAID = intravenous flunixin meglumine injection; VACC = revaccination with an intranasal viral vaccine; VITC = intramuscular vitamin C injection.

² P-values are included for the overall F test.

³Treatment BW was the BW in kg with a calculated 2% shrink.

⁴Treatment ADG was calculated from the shrunk (2%) BW in kg and days on feed between the time periods.

⁵Treatment DMI was calculated by taking DMI in kg for a pen for the period shown divided by the actual number of head days within each pen including mortalities and removals (deads in).

⁶Treatment G:F was calculated by taking the pen ADG in kg divided by the pen average DMI in kg for the time periods.
