摘　　要：[ Objective] The paper was to study the immune activities of Lactobacillus acidophilus 1. 1878 and its effect on antioxidant capacity of broiler chicks. [ Methods] Samples of intestinal mucous, serum and liver were collected from broiler chicks after oral administration of L. acidophilus 1. 1878. Secretory immunoglobulin A （slgA） content in the intestina/mucous, total antioxidant capacity （T-AOC）, level of MDA and activity of SOD and GSH-Px were determined, respec- tively. [Result] Oral administration of L. acidophilus 1. 1878 significantly improved the slgA content in jejunum and ileum mucous （P 〈0.05）. No significant differences were observed in GSH-Px activity between treatment group and control group. The concentration of T-AOC and activity of SOD in serum and liver increased significantly （P 〈 0.05 ）, while the level of MDA reduced significantly after oral administration of L. acidophilus 1.1878 （P 〈 0.05 ）. [ Conclusion ] L. acidophilus 1. 1878 can enhance the immune function of intestinal mucous and antioxidant capacity of broiler chicks.[ Objective] The paper was to study the immune activities of Lactobacillus acidophilus 1. 1878 and its effect on antioxidant capacity of broiler chicks.
