摘要： This study investigated the effects of dietary Enteromorpha powder supplementation on the productive performance, egg quality, and antioxidant performance of Zi geese during the late laying period. Three hundred twelve Zi geese (1 yr old) were randomly allocated into 2 cohorts to form a control group and an experimental group (with each cohort including 6 replicates and 21 female geese and 5 male geese in each replicate). The control group was fed a basal diet, and the experimental group was fed a diet containing 3% Enteromorpha powder. The data showed that Enteromorpha powder supplementation significantly improved egg production, laying rate, average daily egg weight (P < 0.01), and egg yolk color (P < 0.05). Supplementation Supplementation decreased the ADFI and feed conversion rate (P < 0.01). Compared with the control group, glutathione peroxidase (GSH-Px) activity was significantly higher in serum and ovary tissue (P < 0.05), but GSH-Px activity was lower in liver tissue (P < 0.01). Malondialdehyde was reduced in liver and ovary tissue (P < 0.05) in the Enteromorpha powder supplementation group. Meanwhile, the expression of the CAT gene was significantly upregulated in the liver (P < 0.01) in the Enteromorpha group. These results indicate that dietary Enteromorpha powder supplementation improved productive performance and reduced the level of lipid peroxidation in Zi geese during the late laying period.
