What is the likely impact of Ileitis on farm economics?
The economic impact of an Ileitis infection depends on several circumstances. However, the economic margins are negatively affected in any case. The actual economic impact on a specific farm is influenced by the age and number of affected pigs and the severity of the disease (Figure 2.3 a). Figure 2.3 a The economic impact of Ileitis in relationship to the severity of the disease and the number of affected pigs (the circle size is related to the size of the economic impact) . In some farms, a number of pigs may be found with mild or even undetectable clinical signs typical for the chronic form. In farms with the acute form, usually a lower number of animals is affected but with more serious and often including fatal clinical signs. In both situations, the economic effects can be the same (e.g. farm 5 and farm 7 in Figure 2.3 a). Therefore, the economic impact of Ileitis depends rather on the specific farm situation than on the form of the disease (chronic or acute) alone. Pigs affected
