The immune potentials of full dose of bursal derived IBD oil emulsified vaccine (OEV) and a full dose of chick embryo derived IBD oil cemulsified vaccine, were compared. The antibody response was detected by quantitative agar gel precipitation Lest (QAGPT). Challenge studies were also performed. The bursal derived OEV at full and half dose provided higher Immune response and better protection than chick embryo derived OEV, when vaccinated at seventh day of age. A half dose of killed bursal derived IBD OEV is recommended.
