Considerations for Gastrointestinal Cannulation (Rumen, Duodenum and Ileum) in Sheep With a Ruminal, a Simple T-Type and a Modified T-Type Cannula

Abstract

The aim of this study was to investigate the feasibility of simultaneous application of three cannulations and to test the effectivness of a modified T-type cannula compared to simple T-type cannula. A ruminal, a simple T-type and a modified T-type duodenal and an ilial cannula were used in sheep. No complication was encountered in ruminal cannulation. Although no grafts were used, leakage of digesta was not seen for at least five months in T-type cannula and seven months in modified T-type cannula after surgery. Fibrous tissue grew between the serosa of the intestine and the peritoneum. No erosion of the tissue between intestine and body wall was observed after slaughter. Especially ilial digesta was easily obtained from modified T-type cannula.
