title: Immune function of Chinese formula Qingwen Baidu granule in broilers.
abstract: This study was to investigate the effects of Qingwen Baidu granules on the antibody level, immune organ index and the lymphocyte transformation of broilers. Hy-line variety white cocks of 30 days were used to evaluate the antibody titer of Newcastle Disease in each serum group, and MTT method was used to determine the T lymphocyte proliferation, and organ weighing methods to measure the immune organ index 21 days after immunization. The results showed that Qingwen Baidu granules could prolong the residue time in the body, improve the lymphocyte conversion ratio, increase the bursa, thymus and spleen index and promote immune organ development. These results suggested that Qingwen Baidu granules could improve the serum Newcastle disease antibody level, improve peripheral blood lymphocyte proliferation, enhance the cellular immune function, and elevate the immune organ index and growth, in order to raise the immune function in chicken. The above demonstrates that the Qingwen Baidu granules have significant effects on the cytoimmunity and humoral immunity, and the potentiation of the immune function in broilers.
