| Background and Aims: The objective of this study was to investigate the effects of Newcastle Disease and Infectious Bronchitis vaccination programs in chickens. Materials and Methods and Results: In the present study, 225 day-old broiler chicks divided into 5 groups. The groups were submitted to vaccinations, except for the non-vaccinated control group. The chickens in the groups 1 were kept as a control group and did not receive vaccine. The chickens in the group 2 were vaccinated with commercial mixed vaccine. The chickens in the groups 3 were vaccinated with two separate vaccines simultaneously. The chickens in the group 4 were vaccinated with single ND vaccine. The chickens in the groups 5 were vaccinated with single IB vaccine. Sera were collected at 18 and 45 days of age and submitted to serologic tests to assess antibody levels. Conclusion: Results demonstrate that there is not any significant statistical difference between the vaccinated groups. |
