Objectives: To evaluate the effects of a cell-free supernatant from (CFSM) on performance and diarrhearelated parameters and the presence of F4+ enterotoxigenic (ETEC) in piglets during post-weaning, and to evaluate the effect of the CFSM on gene expression in an F4+.
Animals And Procedure: In 3 trials with 90 piglets per trial, pigs were assigned to receive a placebo or 1 of 2 CFSM treatments and observed for diarrhea and performance. Fecal swabs were taken to determine the presence of ETEC.
