Abstract

Bovine respiratory disease continues to be the greatest threat to calf health. One of the common recommendations is to vaccinate young beef and dairy calves at 30-60 days of age to provide protection at weaning or when commingled. The study objective was to determine whether there were any dif­ferential leukocyte changes that could be measured following a dual challenge with Bovine Viral Diarrhea Virus (BVDV) and M. haemolytica ~5 months after vaccination.
