Subclinical ileitis: Diagnostic and performance parameters in a multi-dose mucosal homogenate challenge model

Abstract

A dose titration study was conducted using a Lawsonia intracellularis mucosal homogenate model in weaned pigs. Significant negative effects on performance were observed in the absence of positive diagnostic indicators or clinical signs. The results obtained showed that subclinical infection can have a detrimental economic impact on swine herds.
