Review: Vaccination against respiratory pathogens during the cow-calf phase: Effects on productive and health responses of feedlot cattle

Abstract

Purpose

Bovine respiratory disease (BRD) remains one of the costliest diseases affecting the beef industry, and vaccination is a key strategy to mitigate disease risk. This article discusses current knowledge of vaccine use and strategies during the cow-calf phase of beef production.

Sources

The primary source of information reviewed herein was independent, published, scientific peer-re- viewed literature.

Synthesis

Producers prioritize vaccination protocols as cattle progress through the segments of the beef pro- duction system, with BRD vaccine adoption rate increas- ing as cattle age. Vaccination against BRD pathogens dur- ing the cow-calf phase and before stressful events such as weaning, transportation, or feedlot entry enhances vaccine efficacy and health responses in feedlot cattle.

Conclusions and Applications

To maximize vac- cine effectiveness and ensure optimal protection from disease, the timing of vaccinations against BRD pathogens relative to disease challenge must be considered. Research is warranted to further explore the benefits of vaccination against BRD pathogens during the cow-calf phase on cattle health and performance during the feed- lot period.
