1. Nutritional encephalomalacia may be induced in chicks up to the age of approximately 2 months. As the preliminary feeding period on a natural foods diet is increased, the percentage incidence of the disease becomes progressively less. The average time between institution of diet and appearance of the disease tends to diminish.
2. There is no correlation between growth and incidence of the disease.
3. White Leghorns, Barred Plymouth Rocks, Rhode Island Reds, and White Wyandottes are equally susceptible.
