| Abstract | ||||
| Fourteen buffalo-calves each was vaccinated twice within 2 weeks interval with 3 ml of the reconstituted inactivated combined vaccine. The vaccinated calves were kept for 6 months in a natural setting with five non-vaccinated control calves. All vaccinated calves remained clinically normal during the observation period, 3 control calves developed symptoms of respiratory disorders and PI - 3 virus was isolated from the nasal discharge of only 2 control animals. IBR virus was isolated at 45 days post-vaccination from the third one, and showed titer of 122 after 2 months, while BVD virus was not isolated from any calf. Results of the SN test against IBR, BVD and PI - 3 antigens indicated that, efficacy of vaccine and the calves should be revaccinated each 6 months from vaccination. | ||||
