Influence of supercritical carbon dioxide of Schisandra chinensis extract on immunity of broilers.In order 

to evaluate the influence of supercritical CO2 of Schisandra chinensis extract on broilers immunity. One 

experiment was conducted in the current study. In the experiment, two hundred 1 d old chicks were used. Chicks 

were randomly divided into 5 groups. The control groups were fed a basal diet, treatments were fed a basal 

diet supplemented with 5 mg kg-1 flavomycin, 0.1%, 0.15% and 0.3% supercritical CO2 of Schisandra chinensis 

extract. Immunity function was tested on the 21 st, 42 nd, and 56 th days. The results showed that supercritical 

CO2 of Schisandra chinensis extract could significantly increase the indexes of thymus in the late growth 

of broilers, the diets which added 0.3% supercritical CO2 of Schisandra chinensis extract could significantly 

increase serum antibody titers to NDV-HI and serum lysozyme activities of broilers, and also significantly increase 

serum IgM and spleen lymphocyte proliferation of broilers. The results showed that Schisandra chinensis could 

improve immunity of broilers.
