[Monensin/sulfachlorpyrazine poisoning in turkeys].

Symptoms of paralysis were observed in seven-week-old turkeys on a farm following administration of sulphachlorpyrazine for coccidiosis. Paralysis was particularly common in the females which were separated from the male birds. Of monensin 122 ppm were found to be present in the feed, whereas the amount stated on the label was 100 ppm. When a new batch was substituted for this feed, the symptoms abated. As the result of a possible interaction of monensin and sulphachlorpyrazine, mortality was 1.7 per cent in the male and 11.2 per cent in the female birds.
