A total of 324 90-day-old beard chickens were randomly divided into six groups (six replicates/group and nine chickens/group). The animals were fed for 40 days, and breast and thigh muscles were collected after slaughter to analyze the antioxidant activity, meat color, drip loss, nutrients, etc. of beard chicken muscles. In terms of the indicators of antioxidant activity, the results showed that EPE could significantly enhance the activity of
