  • Title: [Electromyographical studies on the effects of dorsal and truncal vagotomy upon the motility of abomasum in goats (author's transl)].
    Author: Hara S.
    Journal: Nihon Heikatsukin Gakkai Zasshi; 1979 Nov; 15(3):259-65. PubMed ID: 551231.
    Abstract:
    The vagus nerve was examined electromyographically for effect on the abomasal movement in adult female goats subjected to dorsal or truncal vagotomy. The results obtained are summarized as follows. 1. After dorsal vagotomy, the discharge interval prolonged slightly and the propagation velocity decreased. 2. After truncal vagotomy, the propagation velocity did not show a remarkable change except that the discharge interval showed a tendency to prolong slightly. 3. Neither dysrhythmia nor antiperistaltic discharge was seen after dorsal or truncal vagotomy. 4. The movement of the reticulum showed a tendency to be affected with temperature after dorsal vagotomy. It was not recorded after truncal vagotomy. The goats vagotomized dorsally showed an increase in body weight and decrease in volume of feces accompanied with repeated bloat. The goats vagotomized truncally died of acute frothy bloat 2-10 days after operation. Therefore, it was suggested that truncal vagotomy might have exerted a greater effection all the stomach of the ruminant than dorsal vagotomy, which reduced the movement of rumen more remarkably than the movement of the abomasum.
