Fatty Liver Hemorrhagic Syndrome in Laying Hens

Fatty liver hemorrhagic syndrome (FLHS), a major cause of mortality among caged laying hens, was second (15%) to lymphoid leukosis in 1975 among those hens submitted to the Animal Disease Research and Diagnostic Laboratory from this research station. The disease is characterized by a 20 to 25% increase in body weight, a 25 to 30% decrease in egg production and an Increase in mortality from excessive liver fat and liver hematomas. Two more experiments on this subject have been completed. One used a normal feeding regime and the other used the force-feeding technique described in last year\u27s Poultry Day Report (A.S.
