Alsike clover
General poisoning notes:
Alsike clover (Trifolium
hybridum) is found most frequently in the farming areas of northern Canada.
This plant is adapted to cool climates and heavy, poorly drained clay soils.
Cases of photosensitization have occurred, sometimes accompanied by liver
damage and enlargement. This problem has occurred mostly in horses and
occasionally in cattle. There is also a potential for nitrate poisoning (Cooper
and Johnson 1984, Cheeke and Schull 1985).
