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 Journal of dairy science in 2026 evaluated factors associated with preweaning morbidity, lung consolidation, and mortality in preweaning Holstein calves in Ontario, Canada..
Key Findings
The objective of this retrospective cohort study was to explore factors associated with neonatal calf diarrhea (NCD), bovine respiratory disease (BRD), lung consolidation (LC), and mortality on Ontario dairy farms. Health records from 2,349 Holstein calves from birth until 56 d of age across 9 dairy farms were analyzed using multivariable mixed-effects logistic regression models, which accounted for farm-level clustering through a random effect. The models evaluated associations between the outcomes of interest and season of birth, birth BW, calving ease, first colostrum feeding volume, colostrum quality (measured as Brix percentage), number...
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.
