摘要： The objective of this experiment was to evaluate the antioxidant potential of Allium hookeri (AH) root in two forms, powdered AH root and fermented powdered AH root, to demonstrate its value as an antibiotic alternative feed additive for broiler chickens. A total of 125 male Ross-708 broiler chickens were randomly assigned to five groups (n = 25 birds/group) and fed standard diets supplemented with root or fermented root of AH at two different levels (1% or 5%). Control birds were provided with non-supplemented basal diets. Body weights was measured at days 14 and 21 of age. To monitor antioxidant activities, heme oxygenase (HMOX), aflatoxin B1 aldehyde reductase (AFAR), superoxide dismutase 1 (SOD1), and catalase (CAT) enzyme levels were quantified by real-time PCR in the jejunums 21-day-old birds. Also, serum levels of SOD, CAT, and malondialdehyde (MDA) were measured using commercial kits. The results showed greater body weight gains at day 14 in chickens fed diets supplemented with 1% AH root, as compared to the control group (p < 0.05). Up-regulated transcript levels of AFAR, HMOX1, and CAT were observed in the jejunum of chickens fed diets supplemented with AH. The serum levels SOD and CAT were significantly increased (p < 0.05) in groups treated with AH, whereas MDA levels were decreased in groups fed diets supplemented with AH, as compared to the control group. These results indicated that an optimum level of dietary AH supplementation to young broiler chickens influences growth and improves antioxidant activities.
