Adenocarcinoma of the small intestine of sheep

Abstract

Extract

Although tumours of the gastro-intestinal tract of man are very common, those which have their origin in the small intestine form only a small percentage of the total (Willis, 1953). The situation with respect to animals is not so clear because of the small number of recorded cases, but at least the impression is that tumours of the small intestine are rare. Cotchin (1956), for instance, in a recent review of the literature on neoplasms, of domestic mammals, found only one record of such tumours in the sheep. The almost total absence of reports of this condition in sheep seems most unusual, for, during the past four years, twenty-five cases have been recorded at the diagnostic laboratory of this station, and several have also been seen at the Wallaceville Research Station (Hartley, pers. comm.).
