An Updated Procedure for Cecal Cannulation in Sheep and Cattle

Fifteen cattle (236-500 kg) and 38 sheep (36-55 kg) were fitted with 2 types of indwelling cecal cannulae. Cannulae were made of either clear silicone or plastic tubing. The surgery was conducted in a one-step procedure that involved pharmaceuticals and equipment that were readily available. Results indicated a success rate of 67% (33% failure due to inability to locate the cecum at the time of surgery) in cattle and 100% in sheep. Both cannula types tested were acceptable, but the cannula made from plastic tubing was more desirable because it was less bulky, more durable, and easier to construct. Animals fitted with cecal cannulae appeared to be healthy and to have normal life spans.
