Further physiopathological features of experimental Homeria glauca (Wood & Evans) N.E.Br. poisoning in Merino sheep.

Three Merino sheep were given 3 g/kg of dried, finely-milled Homeria glauca (Natal yellow tulp) plant material intraruminally. Plasma glucose, cortisol, catecholamines and lactate were measured hourly and also at the moment of death. Rising plasma glucose was shown to be associated with rising plasma cortisol and catecholamines, and the metabolic component of tulp-associated acidosis was shown to be the result of lactate accumulation.
