Systematic Veterinary Virology

SYMPTOMS

• The disease spreads rapidly around the farm. Piglets less than 21 days of age are all affected and generally die. Watery diarrhea (foul smelling yellowish-green often containing flecks of undigested milk particles in the piglet), vomiting, weight loss, dehydration and loss of appetite are the common symptoms.
• The weaned piglets become unthrifty. The growers, finishers and adults are generally mildly affected and will survive if their water supplies are adequate (prevention of dehydration). In adult pigs agalactia is a common symptom.
