[Objectives]The current situation of ecologically farming Lidang chicken in Mashan County,Guangxi Zhuang Autonomous Region was investigated and the effects of ecological farming technology on the growth performance,meat quality,and comprehensive benefits of chicken were studied to provide practical ba-sis for the ecological farming of poultry.[Methods]300 Lidang chickens aged 50 days were randomly divided into 5 groups with a rearing period of 100 days.The control group was fed with traditional house and basic diet,while the experimental groups were subjected to housing and mountain/forest grazing and fed with microbial fermented feed and 0.3%Chinese herbal powder.The growth performance and indexes of meat quality were measured to analyze the ecological and economic benefits.[Results]The experimental group with mountain/forest grazing+fermented feed+Chinese herbal powder had the best effect,with a body weight of 1 985 g at 150 days old,a survival rate of 96%,a lean meat rate of 78.71%(14.46%higher than that in the control group),and a cholesterol level only 50%of that in the control group.The ecological farming of Lidang Chicken yielded an average profit of 3 825 RMB per 667 m2,with an average annual increase of 1.47%in slaughter volume from 2020 to 2024 and the vegetation coverage above 85%.[Conclusions]Ecological farming of Lidang chick-ens can significantly improve growth performance,meat quality,and economic benefits,achieving a cycling of farming and planting.It will provide support for the standardization of ecologically farming local chicken breeds.
