Photosensitization of cattle in Montana: is Descurainia pinnata the culprit?

, : Photosensitization of cattle in Montana: is Descurainia pinnata the culprit?. Veterinary and Human Toxicology 31(3): 225-227

Recurrent photosensitization of cattle in Montana has been blamed on Descurainia pinnata, tansy mustard. Two feeding trials were conducted to determine if it was phototoxic. Pen-fed cattle each consumed 2.4 and 4.1 kg/day of the live plant in 2 trials, and no photosensitization was detected. Liver clearance of BSP was within normal limits, as were blood chemistry values for AST, CK and GGT.
