A healthy horse has regular rumbling sounds, which your veterinarian will listen to through a stethoscope. Both regions of the abdomen are listened to, to detect these rumbling sounds. It is essential to detect sounds in all four quadrants of the abdomen. The veterinarian must hear 1 to 3 rumblings per minute. Less than one movement signifies hypomotile which means there is not enough movement. This might lead to diarrhea and needs to be treated immediately. More than 3 movements lead to complications which might be the cause of obstruction. These problems can be treated through regular exercise.
