摘要： Ginger powder (GP) has antioxidant properties and can be a suitable alternative to antibiotics in laying hen diets; however, research on its effects remains limited. Therefore, our study aimed to evaluate the impact of dietary GP supplementation on production performance during the pre-peak production stage. A total of 270 hens, 18 weeks old and averaging 1.83 +/- 0.03 kg, were divided into three groups: control (CN, basal diet), CN + 5 g/kg GP (T1), and CN + 10 g/kg GP (T2), with six replicates of 15 hens each, in a 10-week feeding trial. Dietary GP had no significant effect on feed intake (p > 0.05), but it dose-dependently improved laying rate, egg mass, and feed conversion ratio (p < 0.05). Egg quality parameters, including albumen height, Haugh unit, eggshell thickness, and strength, were also linearly improved with GP supplementation (p < 0.05). Dietary GP linearly enhanced the antioxidant status of hens (p < 0.01) and reduced malondialdehyde activity (p < 0.0001). Furthermore, 10 g/kg GP supplementation slightly improved gizzard index and liver morphology, and it linearly enhanced intestinal morphology (p < 0.01). These findings suggest that 10 g/kg GP supplementation can improve the productivity and health of laying hens.
