Cattle are susceptible to onion poisoning and eating large amounts of this plant can cause death in this species. In areas where culled onions are grown commercially, they can be fed to cattle with few problems when the feed is mixed with ample amounts of other feed components. Poisoning may occur when cool spring weather delays growth of grass and wild onions are available in comparatively large amounts for cattle to graze. Horses and sheep are less susceptible, with goats being the least susceptible. In some cases, sheep may eat onions and show nothing more than slight hemoglobinemia.
