During the large-scale breeding of laying hens,yolk peritonitis occurs frequently,leading to a decline in egg production rate and an increase in mortality and culling rate,which reduces the production performance of laying hens and thus lowers the economic benefits of laying hen breeding,causing economic losses.Various factors can cause yolk peritonitis,such as nutritional factors,disease factors,and management factors,all of which can lead to necrotic enteritis in laying hens.In recent years,the causes of necrotic enteritis in laying hens have been complex and diverse,often presenting as mixed infections or secondary infections,increasing the difficulty of etiological diagnosis,prevention and control,and treatment.This article systematically reviews the various causes of yolk peritonitis in laying hens,aiming to provide a theoretical basis for precise prevention and control and treatment of yolk peritonitis,reduce the incidence of laying hens,thereby reducing economic losses and improving the economic benefits of laying hen breeding.
