Suspected mycotoxicosis in laying hens.
A flock of 15,000 leghorn-type hens experienced a 10% drop in egg production. Enlarged, blue combs and diarrhea were also present. Clinical signs, postmortem and histopathological lesions, and response to therapy were compatible with a diagnosis of mycotoxin intoxication. However, all feed samples submitted were negative for mycotoxins, so the diagnosis could not be confirmed.
