Unravelling the Drivers of Early-Life Mortality in Yak Calves A Retrospective Cohort Study Using Survival Analysis.

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 Animals : an open access journal from MDPI in 2026 evaluated unravelling the Drivers of Early-Life Mortality in Yak Calves: A Retrospective Cohort Study Using Survival Analysis..

Key Findings

Early-life calf mortality is a significant barrier to herd growth and overall productivity in yak husbandry. This retrospective study investigated the survival pattern and potential risk factors linked to yak calf mortality during the first 90 days of life. Analysis was performed on existing farm records from 428 yak calves born between 2013 and 2025 at a semi-intensive yak farm. The Kaplan-Meier method was used to estimate survival probability, and the log-rank test was used to compare survival probabilities; additionally, a multivariate Cox proportional hazards model was employed to identify independent risk factors. Overall, 70 (16.4%)...

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.
