¹Data are least square means of eight observations for all treatments. ESBM = enzyme treated soybean meal (Hamlet Protein Inc., Findley, OH).

²Phase 1 diets, control diet contained 5% ESBM and 2.5% plasma protein; second diet contained 2.5% plasma protein and 5% corn protein; third diet contained 4.5% ESBM and 5% corn protein; and fourth diet contained 10% corn protein.

³Phase 2 diets, control diet contained 7.5% ESBM; second diet contained 5% ESBM and 2.5% corn protein; third diet contained 1% ESBM and 7.5% corn protein; and fourth diet contained 10% corn protein.

⁴Phase 3 diet, common corn–soybean meal diet.

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

⁶Pen days = number of pens × the number of days assessing diarrhea scores.

⁷Frequency = (number of pen days with diarrhea scores greater than or equal to 3/pen days) ×100.

^x,yValues within a row lacking a common superscript letter tend to be different (P < 0.10).
