Abstract: Fatty liver hemorrhagic syndrome (FLHS) is one of the main causes of noninfectious death in cage chickens. It is characterized by fragile liver, rupture bleeding and sudden death. Chicken is easier to form FLHS than mammals because of its physiological characteristics,but the pathogenesis of chicken FLHS is not clear. This paper will elaborate the multiple influencing factors of FLHS disease, such as genetics, nutrition, hormones, environment and intestinal microorganisms. Enumerating and comparing the way of structuring FLHS model by changing diet composition or hormones, and putting forward the pathogenesis of "the multiple-hit" pathogenesis in order to provide a reference for further study of chicken FLHS.

Key words: chicken fatty liver hemorrhagic syndrome, influencing factors, models, the multiple-hit pathogenesis
