This finding is supported by observations reported
by Trckova et al. (2009), who found that kaolinite
in the diet reduced the colonization and shedding of
pathogenic E. coli after weaned pigs were experimentally
infected with an enterotoxigenic F-18 E. coli. The
effects of the clays appear not to be due to binding of
mycotoxins, as the content of mycotoxins in the control
diets used in both Exp. 1 and 2 were less than cautionary
levels (Table 1; van Heugten, 2001).
