Control methods for bovine respiratory disease for feedlot cattle.

Area of Science:

• Veterinary Medicine
• Animal Science
• Immunology

Background:

• Bovine respiratory disease (BRD) remains a significant challenge in cattle production.
• Current standard practices for BRD involve vaccines and antibiotics.
• Effective disease resistance requires a proactive, integrated management strategy.

Purpose of the Study:

• To outline key components of a comprehensive strategy for bovine respiratory disease prevention and control.
• To emphasize the importance of management practices beyond traditional therapeutic interventions.

Main Methods:

• Genetic selection for disease resistance.
• Optimizing colostrum intake and quality.
• Minimizing pathogen exposure through sourcing and handling practices.
• Implementing low-stress cattle handling techniques and facilities.
• Developing and adhering to a comprehensive herd health and immunization program.

Main Results:

• Integrated management practices enhance host immunity and reduce disease incidence.
• Single-source cattle with documented procedures show reduced pathogen exposure.
• Low-stress environments support effective immune function against pathogens.

Conclusions:

• A holistic herd health program, incorporating genetic, nutritional, environmental, and immunological strategies, is crucial for effective BRD management.
• Proactive management and minimizing stress are essential complements to vaccines and antibiotics for controlling BRD.
