Gastroduodenal electrical activity in turkeys.

Bipolar Ag/AgCl electrodes were implanted in the stomach and duodenum of 21 turkeys to study electrical activity in those organs. Intraluminal pressure changes were also monitored. For comparative purposes, electric slow waves were recorded from the stomach of turkeys.

Electrical activity and intraluminal pressures in the lower small intestine of turkeys.

To study ileal motility, 14 young turkeys were surgically prepared with a fistula and 3 bipolar Ag/AgCl electrodes in the ileum. Electric slow waves were recorded which averaged 0.45 mV in amplitude and 6.

The use of strain gage transducers to study gastroduodenal motility in turkeys.

The purpose of this study was to determine if extraluminal strain-gauge transducers (SGT), which have not been tested in birds, could be used to accurately monitor gastroduodenal motility in turkeys. Recordings of gastroduodenal motility obtained from implanted SGT's were compared to recordings obtained simultaneously using measurements of intraluminal pressure (ILP), a method previously used in birds. Frequencies, durations and amplitudes of GI motility as determined by the ILP method were highly significantly correlated with those determined by the SGT method with one exception.
