Paralysis of undetermined origin in bobwhite quail.

Paralysis of undetermined etiology occurred in a group of pen-reared bobwhite quail. Other than severe dehydration, no gross or microscopic lesions were observed, and the cause was not identified. Fumonisin B1 was detected in the feed at 17.7 ppm. In an attempt to reproduce the condition, a feeding trial was conducted utilizing the suspect feed. The feeding trial was not successful in reproducing the symptoms observed in the field case.
