Popis: This study was conducted to investigate the effects of a mixed extract of Cortex Fraxini, Pulsatilla chinensis, and Eucommia ulmoides on growth performance, immune function, and antioxidant capacity in hemp ducks. A total of 90 one-day-old hemp ducks were randomly assigned to 5 treatments, each of which was replicated 3 times (6 ducks in each pen). The treatments were: basal control diet (CON), positive control (PC, CON + 0.5% Astragalus polysaccharides), and CON + 0.25, 0.50, and 1.00% mixed extract. The results showed that the weight of thymus gland increased (quadratic, p
