Evaluating Haemato-Biochemical Parameters Across Chicken Breeds: Insights from a Systematic Review of Selected Studies

Abstract

Background: Understanding the haemato-biochemical parameters of chicken breeds is crucial for optimizing health, productivity, and genetic selection strategies. Despite individual studies on various breeds, a comprehensive comparison and synthesis of these parameters are lacking, leading to fragmented insights into breed-specific physiological profiles.

Objective: This review aims to systematically evaluate and synthesize existing research on haemato-biochemical parameters across different chicken breeds, identifying patterns, variations, and gaps in the current knowledge base.

Methodology: We conducted a thorough search in Scopus, Web of Science, and PubMed, identifying 124 studies initially. Applying rigorous inclusion and exclusion criteria focused on relevance, methodology, and quality, we narrowed our selection to 32 studies for detailed analysis. Our methodology included a thematic analysis to identify common threads and a comparative approach to elucidate breed-specific differences.

Findings: The review revealed significant variability in haemato-biochemical parameters among chicken breeds, with clear distinctions that could be linked to genetic, environmental, and management factors. Key themes emerged around the influence of breed on parameters such as hemoglobin levels, leukocyte counts, and biochemical markers like glucose and cholesterol levels. Several studies highlighted the potential for using these parameters in selective breeding programs to enhance desirable traits.

Conclusion: The systematic review underscores the importance of breed-specific haemato-biochemical profiles in the management and genetic improvement of chickens. It highlights the need for standardized methodologies in future research to enable more accurate comparisons and the development of breed-specific health and productivity strategies.
