In the time from 1st of May 1991 up to the 30th April 1995 in total 101 percutaneus fixations of displaced amomasi were done according to the method of GRYMER and STERNER (1982). In 90 cases it was a displacement to the left side (plus one rezidiv) and eleven cases to the right side. This method of fixation was not difficult. The milkyields of these cows in the year before the illness was higher than the average of the herds. In the year of the percutaneous fixation the milk yield went down, ever it was higher (655 kg = 9.1%) than the average. That of the young cows in first lactation was a little bit lower than the average (3.2%) but in the following year it was a little bit higher (50 kg). In total 17 patients with left side and four cows with right side displacement died or had be slaughtered. First week after surgery eight cows had to be killed due to: hepatitis (5x), foreign body (1x), peritonitis (1x) after fixation, perforated wall of the abomasum (1x). The examination shows, that a great number of cows after percutaneous abomasopexie according to GRYMER and STERNER (1982) can be used for a longer time with economically satisfying results.
