[Objective]The study was to investigate the effects of the complex immune stress induced by Newcastle Disease Ⅳ Series and lipopolysaccharides (LPS) on the growth performance and antioxidant capacity in broilers.[Methods] One hundred and twenty eight 1-day-old broilers were randomly divided into 4 groups.Group A was the control group,and saline was given as blank control;groups B,C,D were vaccinated with conventional dose of Neweastle Disease Ⅳ Series by putting drop in noses on the 15 d and 28 d, and also group C and group D were intraperitoneally injected with LPS 250 μg/kg body weight and 500 μg/kg body weight on 12,15,18 and 21 d for 4 times.After 7, 14, 21, 28 day of inoculation, eight chicken serum samples from each groups were collected to detect the content of malondialdehyde (MDA), and the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX).
