¹A total of 160 weaned pigs (initially 6.3 kg; Line 359 × Camborough; PIC, Hendersonville, TN) were randomly allotted to four dietary treatments with five pigs per pen and eight replicate pens per treatment.

²Data are least squares means of eight observations for all treatments.

³Diarrhea score = 1, normal feces; 2, moist feces; 3, mild diarrhea; 4, severe diarrhea; 5, watery diarrhea.

⁴Pen days = number of pens × the number of days assessing diarrhea scores.

⁵Frequency = (number of pen days with diarrhea scores ≥ 3/pen days) * 100.
