Ryegrass staggers in Canadian wapiti deer

Authors:

Abstract
Extract Sir:- We would like to report an outbreak of ryegrass staggers in Canadian wapiti (Cervus elaphus mannitobensis) which occurred at the Invermay Agricultural Research Centre, Mosgiel. As far as we are aware this is the first recorded case of ryegrass staggers in deer associated with grazing perennial rye grass (Lolium perenne L.).
