Efficacy of yeast and yeast-derived products on growth performance and intestinal morphology of broiler chickens a meta-analysis.

Clinical evidence update from Poultry science

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 Poultry science in 2026 evaluated efficacy of yeast and yeast-derived products on growth performance and intestinal morphology of broiler chickens: a meta-analysis..

Key Findings

The restriction of antibiotic growth promoter use in poultry production has increased interest in alternatives such as yeast and yeast-derived products. However, studies on yeast supplementation have reported inconsistent results. Hence, this study evaluated the effects of dietary yeast supplementation on the growth performance and intestinal morphology of broiler chickens using a meta-analysis and meta-regression approach. A systematic search conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA; 2020) guidelines across three databases found 1,397 records, and 41 controlled broiler studies that...

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.
