Abstract
In two male cattle (ca. 300 kg) there was of correlation between the electromyographic pattern of the abomasum, pressure changes in the antral lumen and the rate abomasal emptying. At times the electromyographic spike activity did not cause either pressure changes or abomasal emptying. It is concluded that the pyloric sphincter regulates the emptying process of the abomasum.
