Integrative metabolic and lipidomic analysis reveals microbiota-associated mechanisms of thigh meat quality variation in spent laying hens from different rearing systems.
This study aims to elucidate the differences in poultry meat quality between cage-rearing (CR) and free-range (FR) rearing systems and to dissect the underlying microbiota-mediated mechanisms. A total of 200 Jianghan laying hens (50-week-old) were equally assigned to either FR or CR group. At 56 w, 10 hens from each gr...
