Protective antibody response following oral vaccination of feral pigeons (Columba livia) with Newcastle disease vaccine (strain I-2) coated on oiled rice.
The novel vaccination technique for feral pigeons was developed in the present study. Multi-age feral pigeons were vaccinated orally with Newcastle disease (ND) strain I-2 vaccine coated on oiled rice. The results showed that 14 days after vaccination 40% of pigeons seroconverted with HI GMT of ≥3 log₂ whereas 28 days after vaccination the seroconversion rate of these birds reached 100%. Moreover, all vaccinated pigeons survived the challenge of virulent Newcastle disease virus (NDV). The findings from the present study indicated that the use of ND (strain I-2) vaccine in feral pigeons is feasible and resulted into the production of protective antibody response. Thus ND I-2 vaccine may prevent the spread of NDV to other birds particularly chickens. Furthermore the use of oral vaccine in feral multi-age pigeons overcomes the difficulty of catching these birds for individual vaccination.
