Global impact of antimicrobial growth promoters on livestock productivity A meta-analysis for economic modeling.

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 global impact of antimicrobial growth promoters on livestock productivity: A meta-analysis for economic modeling..

Key Findings

The use of Antimicrobial Growth Promoters (AGPs) in livestock production is under increasing scrutiny due to concerns about Antimicrobial Resistance (AMR). However, the economic consequences of AGPs withdrawal remain insufficiently quantified, partly because globally representative estimates of their effects on productivity are lacking. This study addresses this gap through a systematic review and meta-analysis evaluating the impact of AGPs on broilers, pigs, and cattle across diverse production settings. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we screened 95 studies encompassing...

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.
