Mallow
Sheep, especially lambs are more susceptible than cattle or horses to poisoning. Most cases occur in the July to October period with some as late as December when Mallow has made up a large part of their diet for days or weeks. Toxicity may be passed to lambs through milk. May contain toxic quantities of nitrate.

Symptoms usually appear after driving some distance and include staggers, sluggish movement, stiff action in the hind legs that are tucked under the body, back arched, head stretched forward, knuckling over of the front legs, sitting with the head turned into the body then lying on one side, trembling, rapid breathing and pulse. If forced to move again they often die, otherwise they rest and recover. Symptoms usually appear a day or two after eating Mallows
