                      The operational site is identified about 4-7 inches (10-15cm) 
                      behind the end of the xiphoid (breastbone) and prepared 
                      according to the preference of the surgeon. (Cleaned, clipped, 
                      scrubbed, sanitized, etc.) At the surgeon's discretion, 
                      the abomasum may be ausculted in this area with a stethoscope. 
                      When auscultating, the cow should be positioned with the 
                      loudest 'ping' in the center of the operational site previously 
                      described. 
                    
                    It 
                      should be remembered that the abomasum will assume its normal 
                      anatomical position under most circumstances, except when 
                      concurrent adhesions or peritonitis might prevent normal 
                      movement to its correct anatomical location. Such cases 
                      are few, but occasionally cause failure to toggle the abomasum. 
                      This condition might merit a laparotomy for further evaluation.

                      Have an assistant place the pressure of a knee, hand, or 
                      foot, on the lower left abdominal quadrant ahead of the 
                      udder, or in lieu of an assistant, the surgeon may elect 
                      to place a knee or foot on the abdomen from the cow's right 
                      side. This will help to ensure that the abomasum is in proper 
                      position and as close to the ventral abdominal wall possible.
