Fatty liver hemorrhagic syndrome
Disease of birds
Fatty liver hemorrhagic syndrome (also referred to as fatty liver syndrome or FLHS), a disease in chickens and other birds. Birds with this disease have large amounts of fat deposited in their liver and abdomen.[1] This often results in an enlarged liver that is easily damaged and prone to bleeding.[2] In some cases the disease is fatal, usually as a result of blood loss from an internal hemorrhage in the liver.[3] The hemorrhage often occurs when a hen is straining to lay her egg.[2] Fatty liver hemorrhagic syndrome is "the major cause of mortality in laying hens."[4]
