Two experiments were conducted to
determine whether 3 different clays in the nursery diet
reduce diarrhea of weaned pigs experimentally infected
with a pathogenic Escherichia coli. Weaned pigs (21 d
old) were housed in individual pens of disease containment
chambers for 16 d [4 d before and 12 d after the
first challenge (d 0)]. The treatments were in a factorial
arrangement: 1) with or without an E. coli challenge
(F-18 E. coli strain; heat-labile, heat-stable, and Shigalike
toxins; 1010 cfu/3 mL oral dose daily for 3 d from
d 0) and 2) dietary treatments. The ADG, ADFI, and
G:F were measured for each interval
