Tiamulin and monensin intoxication in commercial brown pullets.

ABSTRACT: Tiamulin and monensin intoxication has been widely reported in broilers and many other domestic animals, causing muscular dystrophy. This study reports an outbreak of subacute tiamulin-monensin toxicosis in commercial brown pullets and provides a detailed clinicopathological description. The outbreak occurred on a floor-rearing farm in Spain of 21,044 Lohmann Brown pullets (11-16 weeks old) after monensin (120 ppm) was administered in feed and tiamulin (150 ppm) in drinking water. Within 24 h after tiamulin treatment, feed and water consumption declined drastically, and mortality increased progressively, reaching a peak of 1.75%. Cumulative mortality over a 13-day period was 4.3%. Affected pullets (8%) exhibited marked apathy, muscle weakness, flaccid paralysis, and prostration. Necropsy o
