Abstract
The feeding ofhill heifer calves with bracken (Pteridium aquilinum) and dryopteris (Dryopteris juxtaposita) fern @30% w/w of their ration for 24 months resulted in hypoproteinaemia, suppressed humoral immunity, tissue damage and possible initiation of tumor formation. The overall effect of feeding of bracken and dryopteris bas resulted in more or less similar blood biochemical toxicity except for oxidative defense system, which maybe attributed to the composit~onal variation of fern and their toxins.
