Van Es, L., Cantwell, L.R., Martin, H.M., and Kramer, J. (1929) On the nature and cause of "The Walking Disease" of northwestern Nebraska (Necrobiosis et cirrhosis hepatis enzootica) (Research Bulletin: Bulletin of the Agricultural Experiment Station of Nebraska No. 43)
The "walking disease" of Northwestern Nebraska is essentially an enzootic necrobiosis and cirrhosis of the liver due to a toxic agent and does not materially differ from similar disorders occurring in other regions or countries. The disease affects horses and cattle but it is most commonly encountered in the former. The disease in all its clinical and pathological manifestations may be reproduced with the utmost fidelity by the feeding with plants of Senecio riddellii.
