Abstract
An inactivated vaccine including Parainfluenza-3, Pasteurella Multocida and Pasteurella hemolytica stimulated good immunity in calves against an experimental shipping fever challenge. Calves were 1st vaccinated when 4 to 10 weeks old and revaccinated at weaning age. There were higher HI titers, lower temperatures, and less lung lesions recorded in the vaccinated group when compared to the control animals.
