Abstract

THE ingestion of bracken fern causes the death of numbers of young cattle in the South-West of Western Australia every year.

Early experimental work in the United Kingdom demonstrated that bracken contained an anti-Vitamin Bl factor called thiaminase which was thought to be the cause of the poisoning, but later work indicated that a bone marrow poisoning, not yet chemically identified, was responsible.
