Large-leaved lupine
General poisoning notes:
Large-leaved lupine (Lupinus polyphyllus) is a native of British Columbia and has been introduced in eastern Canada. This species has been used in developing many of the cultivars of lupines grown in gardens. Davis and Stout (1986) measured quantities of anagyrine that exceeded the minimum necessary to cause crooked calf disease (teratogenic deformities) in calves. The literature does not include any documented cases. Care should be taken to prevent pregnant cattle from feeding on this lupine from day 40 to day 70 of gestation. See additional notes under silky lupine Lupinus sericeus).
