The effects of dietary ellagic acid supplementation on growth performance, immune response, antioxidant activity, digestive enzyme activities, and intestinal functions in yellow-feathered broilers.

ABSTRACT: This study was conducted to investigate the effects of dietary supplementation with ellagic acid (EA) on the performance, immune function, antioxidant activity, digestive enzyme activities, and intestinal functions in yellow-feathered broilers. In total, 288 healthy yellow-feathered broilers with an average body weight of 39 ± 0.24 g were randomly divided into four treatment groups. Broilers were given a corn-soybean meal basal diet supplemented with 0 (control group), 100, 200, or 400 mg/kg EA. In the finisher period and the overall period, the inclusion of 100, 200, and 400 mg/kg EA increased the average daily gain (P < 0.05), and the inclusion of 200 or 400 mg/kg EA decreased the feed/gain ratio compared with the control group (P < 0.05). The best immune activity (immunoglobulin G [IgG]
