Evaluation of Autogenous Vaccine Use in Mitigating Salmonella in Lymph Nodes from Feedlot Cattle in Texas

What is it about?

The objective of this study was to evaluate the efficacy of an autogenous in mitigating Salmonella prevalence in lymph nodes of feedlot cattle in Texas. Salmonella-positive LNs were only recovered from control cattle, which did not receive vaccinations. Although not conclusive, results suggest that non-vaccinated cattle housed in common with or adjacent to vaccinated cattle may benefit from the protection provided to vaccinated cattle.
