Intestinal pathology of acute diarrhea in weaners: A case control study in 20 Danish herds

The most common cause of antibiotic consumption in Danish pig production is gastrointestinal disorders in weaners. The largest part of the consumption is used as recurring therapeutic batch medication of acute outbreaks of diarrhea. It is generally believed that proliferative enteropathy associated with Lawsonia intracellularis is the major cause of these outbreaks of diarrhea.

The objective of the current study was to describe the gross pathology in outbreaks of acute treatment requiring diarrhea in pigs between 10 and 70 days post weaning. Results of clinical and microbiological investigations of these outbreaks are reported elsewhere in these proceedings.
