Abstract
The effects of extracts of the bursa of Fabricius on the return to normal and greater than normal of antibody production in hormonally bursectomized chickens and on the switch-over of IgM antibody production to IgG antibody production was studied. Antibody production in hormonally bursectomized chickens treated with bursal extract was markedly increased as compared with bursectomized birds not given bursal extract and the IgG antibodies at three weeks was similar to that in normal immune chickens.Entities:
