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. A study was designed to determine if vaccination in the face of maternal an­tibody would provide protection against a dual challenge with bovine viral diarrhea virus (BVDV) and Mannheimia haemolyti­ca ~5 months after vaccination.
