^a–cMeans within a row lacking a common superscript letter differ (P < 0.05)
¹Data are least square means of 13 to 19 observations per diet
²SDP Spray dried plasma
³P-values were calculated for the main effects of sow treatment (S) and nursery diet (N) and the interaction between sow treatment and nursery diet (S × N)
⁴Diarrhea scores were visually assessed every other day by 2 independent observers for 36 days. Diarrhea score = 1, normal feces; 2, moist feces; 3, mild diarrhea; 4, severe diarrhea; 5, watery diarrhea
⁵Frequency = (number of pen days with diarrhea scores ≥ 3/pen days) × 100
