Determinants of mortality from bovine respiratory disease in Australian feedlot cattle A survival analysis.

Clinical evidence update from Preventive veterinary medicine

Clinical Context

Peer-reviewed veterinary literature continues to shape everyday decision-making for production animal practice, especially when new evidence clarifies diagnosis, treatment selection, monitoring, or clinical outcomes.

What the Study Evaluated

A study published in Preventive veterinary medicine in 2026 evaluated determinants of mortality from bovine respiratory disease in Australian feedlot cattle: A survival analysis..

Key Findings

Bovine respiratory disease (BRD) is the leading cause of morbidity and mortality in Australian feedlot cattle, yet large-scale quantification of risk factors for BRD-specific mortality using time-to-event methods remains limited. A retrospective cohort survival analysis was conducted on 1,040,253 cattle from 7825 lots across three Australian feedlots inducted between 1 January 2018 and 5 December 2024 to characterise temporal patterns, identify risk factors, and assess attenuation pathways for BRD-specific mortality within 90 days on feed. The survival analysis was carried out using Cox proportional hazards and time-stratified models,...

Why It Matters for Veterinary Professionals

For veterinary professionals, the practical value of this work lies in how the findings may support more structured clinical assessment, clearer monitoring, and more informed decisions for production animal practice.

Practical Interpretation

The results should be interpreted in the context of the study design, population, inclusion criteria, and clinical setting. Application in practice should consider patient-specific risk factors, available diagnostics, local standards of care, and clinician judgment.

Clinical Takeaway

Overall, the study adds useful evidence for clinicians seeking to align daily practice with current veterinary research while maintaining a balanced, case-by-case approach.
