Abstract:
two-week-old chickens were randomly divided into treatment group(T)and control group(C)in this experiment.Newcastle Disease I Series(NDI)was taken as the source of immunological stress;the muscles of chicken group T were inoculated with 2 close per chicken to induce immunological stress,and group C wasn't given any treatment. The effects of immunological stress on blood hormone level and immunity Function of experimental chickens were detected at different time after inoculation.The results shows that content of ACTH,Cor and T4 in the blood of group T were higher(p<0.05) or significantly higher(p<0.01) than that of group C;The reaction properties of T-lymphocyte in blood to PHA decreased greatly, the total content of IgG in serum first decreased and later increased.There is negative correlationship between the content of Cor in blood and the transformation rate of T-lymphocyte,and there isn't any correlationship between the content of Cor in blood and the change of IgG in serum. Result indicated that,after the occurrence of immunological stress,ACTH、Cor and T4 in chicken blood will change evidently,the immunological function of humoralwas first restrained, then inhanced;the immunological funct ion of cell was restrained,too.
