[Results of treatment by rotation in left-sided abomasal displacement (author's transl)]

The results are given of the treatment of thirty cows with left-sided abomasal displacement by rotation, followed by intravenous injection of hypertonic sodium chloride solution and a calcium borogluconate solution. In addition, ammonium chloride was administered orally for a few days. The rations of the animals were gradually restored to normal levels. The purpose was to examine whether recurrences following rotation could be prevented by supplementary measures. Of these thirty animals, five did not respond to treatment because of complications that would otherwise not have reacted favourably to any form of treatment either. Correction of the abomasal displacement was successful in more than 90 per cent (23 animals) of the remaining five cows. However, abomasal displacement recurred in sixteen of these twenty-three animals (70%). Of these fourteen cows, two animals developed an abomasal torsion. It is concluded that the supplementary measures adopted will not prevent recurrences.
