Pregnancy disease is a highly fatal, acute metabolic disease affecting pregnant ewes during the last few weeks of gestation. It is characterized by acetonemia with fatty infiltration of the liver and is often associated with a low blood sugar. The condition is found wherever sheep are raised; it has been variously called stercoremia, lambing paralysis, prenancy toxemia, and lamzietke, ketosis, domzietke, acidosis, preparturient paresis, and hypoglycemic encephalophaty, snow blindness, and twin lamb disease. The entity has been widely studied if not always well studied.
