Abstract

A single inoculation of combined vaccines of Newcastle disease and avian infectious bronchitis of chicken, in a form of gel-oil emulsion type (gel-OEV) was tested their immunogenecity in chickens. The results were summerized as follows: 1. Average minimum and maximum ELISA antibody titers of ND were recorded 2407 and 13144 respectively. In the case of IB, 1824 and 4496 were recorded as minimum and maximum titers. 2. The distribution of average proportional groups, in the lowest and the highest, were 1.6 and 7.0 in ND ELISA and 1.4 and 2.8 in IB ELISA antibody titers. 3. ND ELISA antibody titers were significantly increased upto 7th week after the vaccination. On the other hand, IB ELISA antibody titers were raised upto 4th week after the vaccination.
