Clinical and Pathological Impact of Fatty Liver Hemorrhagic Syndrome in Caged Hens Farms in Diyala Province

Abstract

The aim of present study was to show the Fatty liver hemorrhagic syndrome (FLHS) in different areas of Diyala province and its effects on the eggs production. A total of 250 layer hens from different areas of Diyala Province (44) weeks suffering from pale appearance, anorexia, low weight and low egg production without any other signs refers to an outbreak of known infectious diseases were enrolled. Post mortem signs show enlargement of livers in the most cases with fatty appearance. The microscopic study appears the fatty change in hepatic section. The weights of layer hens, blood parameters, lesions score were studied. The results showed higher incidence of case in 11.6% the oldest layer hens in compare with 0.8% the youngest and low weights of affected farms at 31 and 64 wks of age. Birds of Farm 3 had a significantly higher BW than that recommended for Isa brown. No significant increase of all blood parameters measured at 73 wks of age in Farm 1. No significant changes in blood cell profile of hens at different flocks/ages at Farm 1. FLHS cause a significant economic loss by dropping of egg production and mortality increases.
