It is well established that pigs suffering from Ileitis have to eat more feed per kg gain and have higher feed costs than healthy pigs (Gebhart and McOrist 1999). This leads to the obvious question whether differences in the feed conversion can be mirrored in the Ileitis seroprofile (Fig. 2.1.7a). Figure 2.1.7a Ileitis ELISA values in farms with good feed conversion (2.75 kg feed per kg gain) in fattening. * means with non overlapping 0.95 confidence intervals are significantly different. Farms with poor feed conversion showed significantly higher Ileitis ELISA values in the fattening period than farms with good feed conversion. Jacobson et al. (2003) came to the same conclusion by comparing a wide range of enteric pathogens in good and poor performing herds. In addition to L. intracellularis being the most common cause of infectious enteric disease in growing pigs, there was a significant correlation between poor performance and the presence of L. intracellularis and B. pilosicoli.
