“…The root of R. glutinosa also contains some biologically active substances, such as iridoids, monoterpenes, glycosides, saccharides, amino acids, and organic acids (22). Many clinical and experimental studies have shown that R. glutinosa possesses various pharmacological properties, such as hemostatic (23), antifatigue (24), immune enhancement (25), antitumor (26), antiinflammatory (6), and antioxidant (27) activities. Thus, in our study, improved production performance and egg quality might also be due to overall improvement of the health of FPFA-supplemented layers.…”
