Clinical signs and forms of ileitis
The forms of presentation of ileitis in pigs are haemorrhagic or acute, chronic and subclinical.
The acute form affects young adults from four to 12 months of age, usually replacement gilts or hogs close to market age. It is characterized by an acute haemorrhagic syndrome with profuse bloody diarrhoea or sudden death (McOrist & Gebhart, 2012). Black tarry faeces are often seen at the beginning of the clinical presentation, or when the animal is recovering after being affected by a mild case.
