HSBM−, LSBM− = high soybean meal (HSBM), low soybean meal (LSBM) without PRRS; HSBM+, LSBM+ = high soybean meal (HSBM), low soybean meal (LSBM) with PRRS; dpi = days post inoculation; PRRSV = porcine reproductive and respiratory syndrome virus.

¹Main effect of diet, PRRS, and interaction of PRRS × diet.

²ATTD = apparent total tract digestibility.

³AID = apparent ileal digestibility.
