ABSTRACT
Raghu TK, Nagaraja TR, Kumar APc,
Mishra SC, Mortality and antibodies to
bursal disease in fowl by oil, vitamin A and E vaccines. Onl J Vet
Res., 30 (2): 66-72, 2026. Groups of 2 week old chicks were vaccinated
subcutaneously with oil, vitamin A and vitamin E adjuvanted
live infectious bursal disease (IBD) vaccines. IBD live-in-oil vaccine, vitamin
A and E adjuvanted IBD live-in-oil vaccine and IBD
live vaccine adjuvanted with vitamin A and E (injected
adjacent to live vaccine) Of groups of 10 chicks challenged with the disease,
those given only IBD vaccine we found 5/10 dead chicks by 10 days, with IBD and
oil none, IBD and vitamin A 3 dead, IBD vitamin A and oil 5 died whereas no
controls died. However, IBD with Vitamin E none died and IBD vitamin E with oil
1 death. Ten days after challenge, comparing antibody titres with controls, we
found IBD vaccine boosted antibody 3.4 fold, IBD with oil 3.6 times, IBD vitamin
A 3.7 fold with IBD with oil 4 fold, vitamin E 3.65 times, IBD with oil 3.8
fold and controls 23 fold by 10 days.
