ABSTRACT
A method of telemetric recording of myoelectrical activity (EMG) in the female pig reproductive
tract is described. In 10 gilts the telemetry implant was placed extraperitoneally between the abdominal
muscle layers and connected with two or three bipolar silver electrodes sutured on different parts
of the uterus and oviducts. The animals recovered from surgery quickly and without complications.
The radio waves sent by the implant were collected and demodulated by a receiver and then recorded
on a computer disk. Two-three h recording sessions were performed every 2-3 days. The electrodes
collected EMG signals free of artifacts for 5-6 weeks after surgery. Off-line analysis of myometry
and oviduct EMG activities showed no major differences from the activities measured earlier by
conventional wire methods. In conclusion, a commercially available telemetry system can be used
for reproductive tract myoelectric activity studies in pigs.
