1921: Frank Schofield, a Canadian veterinary pathologist, determines that the cattle were ingesting moldy hay made from sweet clover. Only spoiled hay made from sweet clover (grown exclusively in North America) produced the disease . (cont’d)
Schofield separated good clover stalks and moldy clover stalks from the same hay mow, and fed each to a different rabbit 🐰.
