Toxicity of Beta-Aminopropionitrile for Turkey Poults. ∗

Abstract

Summary

(1) Beta aminopropionitrile hydrochloride was toxic to turkey poults at levels as low as 0.01% of diet. (2) Paralysis. degeneration of anterior motor neurons and growth depression were the chief abnormalities observed at 0.25% and 0.125% while pericardial and pulmonary hemorrhage, ruptured aortas, leg and toe deformities, and growth depression were the primary symptoms at lower levels. (3) Preliminary attempts to alter severity of symptoms by reducing the methionine level or by adding vit. B₁₂ or a high level of all B vitamins were not very successful, but further investigation of the B vitamins appears to be justified.
