Background Intestinal disease in nursery pigs is the most common cause of antibiotic usage in pigs in Denmark. The decision to initiate batch medication of intestinal diseases in nursery pigs is typically made by the stock personnel based on clinical assessments of pigs and counting of diarrhoeic faecal pools on the pen floor. The target population of this study was batches of nursery pigs (10–66 days after weaning) where the stock personnel assessed the pigs to be without signs of intestinal disease and therefore did not needed treatment. The objective was to determine the within-herd prevalence of diarrhoea, and to determine the prevalence of Escherichia coli F4 and F18, Lawsonia intracellularis and Brachyspira pilosicoli by quantitative PCR in pigs with and without diarrhoea.
