Fatty liver hemorrhagic syndrome
Fatty liver hemorrhagic syndrome (also referred to as fatty liver syndrome or FLHS), a
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]
Causes
Excessive
egg production.[2]
As a result, death can occur quite unexpectedly.
Symptoms
Affected birds are usually overweight and may also have pale combs.[1] Generally, however, the disease has few or no symptoms prior to the bird's death.[6]
Treatment
Additional information needed
The use of
L-Tryptophan in the diet can decrease the syndrome.[7]
