Résumé

Cramming of geese is an ancient skill (2,500 years B.C.) that has allowed "foie gras" production. The hepatic steatosis which develops as a result of over-feeding is particularly dramatic: in less than two weeks the liver weight may increase tenfold. The liver has a composition which does not depend on the length of the force-feeding period, but only on its weight. "Foie gras" formation is a reversible process: after a long fasting period, birds recovered their initial live weight and a liver with the same characteristics (weight, composition, histological structure) than those observed in never force-fed controls. It seems that cramming does not really hurt the birds. There is no symptom of acute or chronic stress.
