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

evaluate the influence of supercritical CO2 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 mgkg-1 flavomycin, 0.1%, 0.15% and 0.3% supercritical CO2 Schisandra 

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

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

late growth of broilers, the diets which added 0.3% supercritical CO2 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.
