Abstract
Biochemical and hematological analyses of blood and serum were performed in pigs with regional ileitis and in wasting pigs with a negative necropsy. In sera from pigs with regional ileitis the levels of total protein, albumin, transferrin, alkaline phosphatase and zinc were significantly decreased compared with normal pigs of the same age. The number of white blood cells, and the concentration of Cortisol and α1-antitrypsin were significantly increased. In wasting pigs with early signs of regional ileitis or with a negative necropsy the same blood changes were observed but to a less degree. It was concluded that a wasting syndrome after weaning may precede regional ileitis. Concerning the etiology of regional ileitis the significance of malabsorption and wasting syndrome in combination with invasion of intestinal intercellular microorganisms is discussed.
