Experimental study demonstrates fatal cerebellar lesions and ataxia in chicks on a purified diet, indicating a critical nutritional deficiency.

To describe the clinical manifestations and neuropathological changes associated with a nutritional cerebellar disorder in growing chicks.
Maintained growing chicks on a defined experimental diet consisting of milk powder, casein, starch, yeast, cod liver oil, salts, and filter paper.
Monitored birds for onset of neurological signs and performed post-mortem histological examinations of the brain.
Chicks developed acute neurological signs—including ataxia, tremors, head retraction or twisting, clonic leg spasms, and stupor—predominantly between days 18 and 25.
Neurological episodes frequently ended in death, though some chicks recovered and resumed normal development.
Histopathological analysis revealed cerebellar lesions featuring edema, necrosis, hemorrhages, and capillary hyaline thrombi in degenerated areas.

Pappenheimer et al. (1931) studied this question.
