A method for recording the motility of the reticulum in normal cattle has been devised. The method is based on measurement of the pressure variations occurring in connection with the reticular contractions. The pressure is transferred through open, water-filled catheters via a pressure transducer to an electromanometer, from which it is recorded with the aid of a mingograf. Mean values for the interval, duration and amplitude of the reticular contractions in 10 normal cows are given. The method permits recording in intact animals without any preliminary measures, and can therefore be used in clinical cases.
