羽毛断层带(Fault Bars)的形成机制及在家禽福利评价中的研究进展
Formation Mechanism of Feather Fault Bars and Research Progress in the Welfare Assessment of Domestic Poultry
摘要
Abstract
Fault bars are structural deformities formed during feather growth due to disrupted keratin synthesis,leading to weakened or fractured barbules,loss of vane integrity,and conse-quently impaired flight capacity and survival adaptability in birds.Studies on wild birds have shown that the occurrence of feather fault bars may be associated with multiple factors,such as nutritional deficiencies,environmental stressors,disease infections,and genetic predispositions.Although the exact etiology remains unclear,it has been widely accepted that physiological or psychological stressors during feather growth can induce fault bars formation.In modern farming systems,poultry are frequently exposed to multiple stressors in the high-density environment,compromising their welfare status.However,evaluating stress level in poultry remains a persis-tent challenge in practical welfare assessments.Recently,fault bars have gained attention as a non-invasive,practical,and promising biomarker for poultry welfare evaluation.This review synthesizes the influencing factors and formation mechanisms of fault bars,as well as their cur-rent applications in poultry welfare assessment,aiming to provide insights for improving poultry welfare evaluation systems.关键词
