Abstract: 【Objective】 This experiment aimed to investigate the effects of Acremonium terricola culture (ATC) on the growth performance,slaughter performance,hematological parameters,serum biochemistry,and antioxidant capacity of Pekin ducks. 【Method】 A total of 216 one-day-old healthy male Pekin ducks (51.36 g±0.15 g) were randomly divided into three groups,each with eight replicates and twelve ducks per replicate.The ducks were fed a corn-soybean meal-based basal diet supplemented with 0 (control group),0.1% and 0.2% ATC.The feeding trial lasted for 42 days.Growth performance and slaughter performance were recorded,and whole blood and serum samples were collected to measure hematological parameters,serum biochemical indexes,and antioxidant indicators. 【Result】 ① There was no significant effect of dietary 0.1% and 0.2% ATC supplementation on the growth performance of Pekin ducks (P>0.05).② The breast muscle yield of Pekin ducks in 0.1% ATC group was significantly higher than that in control and 0.2% addition groups (P<0.05),and the liver index of Beijing ducks in 0.2% ATC group was significantly lower than that in control group (P<0.05).③ Compared to control group,in 0.2% ATC group,lymphocyte (LYM) and monocyte (MID) counts,and red cell distribution width standard deviation (RDW-SD) of Pekin ducks were significantly increased,while white blood cell (WBC) and granulocyte (GRA) counts of Pekin ducks were significantly decreased (P<0.05).④ Compared to control group,the serum glucose level of 0.1% and 0.2% ATC groups were significantly decreased,and serum triglyceride level of 0.1% ATC group were significantly decreased (P<0.05).⑤ Compared to control group,the serum activities of T-SOD,CAT,and GR of 42-day-old Pekin ducks in 0.1% and 0.2% ATC groups were increased (P<0.05).Additionally,compared to control and 0.1% ATC groups,the serum activities of GSH-Px and T-AOC of 42-day-old Pekin ducks in 0.2% ATC group were significantly increased (P<0.05). 【Conclusion】 Dietary supplementation with 0.1% and 0.2% ATC did not improve the growth performance or organ development of Pekin ducks,but it significantly increased breast muscle percentage,enhanced immune and antioxidant capacities,and promoted glucose and lipid metabolism.
