Porcine Postweaning Wasting/Catabolic Syndrome (PWCS): pathological features

21-10-2010 | | |

Porcine Postweaning Wasting/Catabolic Syndrome (PWCS) is an emerging condition causing elevated nursery mortality1. Affected pigs, weaned in robust body condition, develop anorexia and most become severely emaciated and die within 3 weeks of weaning. Mortality rates wax and wane and reach 10% in peak months.

The cause of PWCS is unknown, but an infectious etiology suspected. Pathogens including PRRSV, porcine circovirus 2, rotavirus, transmissible gastroenteritis virus, influenza virus, Lawsonia intracellularis, Mycoplasma hyopneumoniae, Helicobacter spp., Campylobacter spp., calicivirus and coccidia were not causally related to PWCS2 (and unpublished data). The objective of the current study was to characterize the pathologic changes in PWCS-affected pigs.
