Three replicate trials were conducted using different sows. Each trial was composed of two groups (up to 45 piglets per group). Piglets in the control group were fed antimicrobial-free diets. In the treatment group, piglets received three different antimicrobial feed additives during the growth period. Sowsreceived antimicrobial-free diets starting at 100 days of age, and gestation and lactationdiets were antimicrobial-free. Piglet diets wereidentical in formulation and physical form/processing except for the addition of AFAs for the treatment group.

Sows and piglets were sampled at regular intervals for fecal E. coli, and recovery of 12 E.coli isolates per animal was attempted at each sampling.
