Animals were fed experimental diets from 17 to 24 days of age but were not infected with E. coli K88 until they were 24 days old (after 7 days on the experimental diets).
Pooled standard error of the mean.
BI, before inoculation, calculated from the day of weaning until inoculation (17 to 24 days of age).
AI, after inoculation, calculated from the day of weaning until inoculation (24 to 34 days of age).
0, normal feces; 1, mild diarrhea; 2, diarrhea; 3, severe diarrhea.
Means within rows without common letters differ (P < 0.05).
