Encephalomalacia associated with hypovitaminosis E in turkey poults.

Four-to-five-week-old turkey poults fed a diet markedly deficient in vitamin E (alpha-tocopherol) abruptly developed neurologic signs such as tremor, incoordination, and recumbency shortly after being moved to new quarters. Serum concentrations of alpha-tocopherol in birds on this diet were significantly lower than control values. Associated lesions included recent ischemic necrosis of the cerebellum and spinal cord. The condition closely resembled nutritional encephalomalacia of chicks. This report represents the initial published description of that entity in turkeys.
