By determining the maternal antibody titre against IBDV. The protective efficacy of vaccines 228-E, BUR-706 and Gumboral CT was also evaluated by challenging the vaccinated birds with virulent IBD virus. A total of 200 day-old birds were randomly divided into four equal groups designated A, B, C and D. Chicks of group A, B and C were vaccinated with 228-F, BUR-706 and Gumboral CT, respectively. Group B served as un-vaccinated control. ELISA was found more sensitive than AGPT and IHA in determining maternal antibody titre. Higher antibody titres were produced by 228-F compared to BUR-706 and Gumboral CT, respectively. Maximum mean ELISA titres in group A, B, C and D on day 35 were 10,080, 8539, 7022 and 537, respectively. Decline in maternal antibody titre was observed weekly. AGPT could detect it up to day 14, while IHA up to day 2] and ELISA up to day 35. 228-F [Intermediate Hot (Plus) strain] provided maximum protection in vaccinated birds when challenged on day 20 and day 35 post-vaccination.Item type | Current location | Collection | Call number | Status | Date due | Barcode | Item holds |

The present project was aimed at determining the comparative sensitivity of AGPT, IHA and ELISA. By determining the maternal antibody titre against IBDV. The protective efficacy of vaccines 228-E, BUR-706 and Gumboral CT was also evaluated by challenging the vaccinated birds with virulent IBD virus.

Group B served as un-vaccinated control.
ELISA was found more sensitive than AGPT and IHA in determining maternal antibody titre. Higher antibody titres were produced by 228-F compared to BUR-706 and Gumboral CT, respectively. Maximum mean ELISA titres in group A, B, C and D on day 35 were 10,080, 8539, 7022 and 537, respectively.
Decline in maternal antibody titre was observed weekly. AGPT could detect it up to day 14, while IHA up to day 2] and ELISA up to day 35.
228-F [Intermediate Hot (Plus) strain] provided maximum protection in vaccinated birds when challenged on day 20 and day 35 post-vaccination.
