[Stomach dilatation-stomach torsion syndrome: a 'new' clinical picture in sows?].
Increased mortality occurred among sows in a pig-breeding unit during a few months. It was concluded that gastric torsion was one of the causes of death. This disease is becoming increasingly important in large intensive units, also in the Netherlands. Little is so far known of the origin of this syndrome. The feeding system and the quality of the food (fine-grained feed, contamination by toxic agents) could be a factor in the pathogenesis. Closer investigation of this economic problem would appear to be advisable.
