The experimental results firstly demonstrate that the immunorcgulation of IL-2, and IL-2 receptor, the cellualr and humoral immune responses were significantly enhanced in the central and peripheral immune organs; the local mucosal immune function were markedly amplified in the respiratory and digestive tracts of the immunized-challenged,chicks, which were closely correlated with the immunoprotection against MD; the immune response and immunoprotective effect of the trivalent vaccine-immunized chicks were much better than those of HVT vaccine-immunized chicks:展开更多
