摘要
Previous investigation demonstrated that oral administration of ginseng stem-leaf saponins in chickens could enhance the immune response. The present study was designed to evaluate the effects of ginseng stem-leaf saponins on oxidative stress induced by cyclophosphamide in chickens. One hundred and twenty chickens were randomly divided into 5 groups. Groups 1 to 4 received intramuscular injection of cyclophosphamide to induce oxidative stress while group 5 was injected with saline solution and served as control. Following administration of cyclophosphamide, groups 1 to 3 were orally administered ginseng stem-leaf saponins at 2.5, 5, and 10 mg/kg BW in drinking water for 7 d, respectively. After that, the spleen, thymus, bursa, and serum were collected to measure the indices of the organs and oxidative parameters. The results showed that ginseng stem-leaf saponins significantly inhibited cyclophosphamide-induced oxidative stress by increasing the organ indices, total antioxidant capacity, and the levels of glutathione, ascorbic acid, and a-tocopherol, while elevating the activity of total superoxide dismutase, catalase, and glutathione peroxidase, as well as decreasing the protein carbonyl content and malondialdehyde. Therefore, ginseng stem-leaf saponins could be a promising agent against oxidative stress in the poultry industry.
