- Abstract
This study investigated the effect of glutamine (Gln) on antioxidant capacity of cold-stressed chicks. A total of 192 1-day-old Arbor Acres (AA) broilers were divided into 4 groups: group I was fed basic diet, groups II, III, and IV were fed with addition of 1.0%, 1.5%, and 2.0% Gln. The house temperature was maintained at 25 ± 2 °C. Compared with group I, on day 7, the activities of catalase (CAT) and glutathione peroxidase (GSH-PX) in serum and jejunum, GSH-Px in duodenum of group II, the CAT and GSH-Px activities in ileum of group III, the GSH-PX and total antioxidant capacity (T-AOC) activities in jejunum in group IV were increased (P < 0.05). The malonic dialdehyde (MDA) content in serum was decreased (P < 0.05). On day 14, the jejunum CAT and superoxide dismutase (SOD) activities in group II were increased (P < 0.05), and the serum MDA content was reduced (P < 0.05). CAT activity of jejunum and ileum, and GSH-PX activity of serum and jejunum were increased in group III (P < 0.05). The jejunum GSH-PX activity was increased in group IV (P < 0.05). The experiment confirmed that adding Gln to the diet can improve the antioxidant capacity of cold-stressed chicks.
