摘要： Background Caffeic acid (CA) and its derivative, chlorogenic acid (CGA), have shown promise in preventing and alleviating fatty liver disease. CA, compared to CGA, has much lower production costs and higher bioavailability, making it a potentially superior feed additive. However, the efficacy, mechanistic differences, and comparative impacts of CA and CGA on fatty liver disease in laying hens remain unclear. This study aimed to evaluate and compare the effects of CA and CGA on production performance, egg quality, and fatty liver disease in laying hens. Results A total of 1,440 61-week-old Hyline Brown laying hens were randomly divided into 8 groups and fed diets supplemented with basal diet, 25, 50, 100 and 200 mg/kg of CA, and 100, 200 and 400 mg/kg of CGA (CON, CA25, CA50, CA100, CA200, CGA100, CGA200 and CGA400, respectively) for 12 weeks. Both CA and CGA improved production performance and egg quality, while reducing markers of hepatic damage and lipid accumulation. CA and CGA significantly decreased TG, TC, and LDL-C levels and increased T-SOD activity. Transcriptomic and proteomic analyses revealed that CA and CGA reduced hepatic lipid accumulation through downregulation of lipid biosynthesis-related genes (ACLY, ACACA, FASN, and SCD1) and enhanced lipid transport and oxidation genes (FABPs, CD36, CPT1A, ACOX1, and SCP2). Of note, low-dose CA25 exhibited equivalent efficacy to the higher dose CGA100 group in alleviating fatty liver conditions. Mechanistically, CA and CGA alleviated lipid accumulation via activation of the ADPN-AMPK-PPAR alpha signaling pathway. Conclusions This study demonstrates that dietary CA and CGA effectively improve laying performance, egg quality, and hepatic lipid metabolism in laying hens, with CA potentially being more economical and efficient. Transcriptomic and proteomic evidence highlight shared mechanisms between CA25 and CGA100. These findings provide a foundation for CA and CGA as therapeutic agents for fatty liver disease and related metabolic diseases in hens, and also offer insights into the targeted modification of CGA (including the isomer of CGA) into CA, thereby providing novel strategies for the efficient utilization of CGA.
