Two pairs of chicken lines were developed from individual phenotypic selection for serum immunoglobulin M and G levels at 10 weeks of age. After three generations of selection, the lines were tested for their competences to graft-vs-host reaction (GVHR) and antibody response to brucella abortus (BA). Serum immunoglobulin M and G levels changed significantly (P<0.05) during the selection period. Splenomegaly indices, used to measure GVHR competence, differed significantly (P<0.05) between the high IgG (KG) and low IgG (LIG) lines. Total BA antibody titers also differed significantly (P<0.05) between the KG and LIG lines at 7 day postimmunization. The selected lines showed their divergence in T and B cell responses although the selection was conducted on the basis of serum immunoglobulin isotypes.
