Age and Sex-Associated Variations in Hematological and Oxidative Stress Profiles of Geese

Why It Matters

The data give producers precise reference values to detect abnormal health trends, enabling targeted interventions that can improve flock welfare and productivity.

Key Takeaways

• Eosinophils higher in male geese; monocytes higher in females
• Females show increased TOS and OSI, TAS unchanged across sexes
• Young geese have higher erythrocyte counts and hematocrit
• Adult geese display higher leukocytes, heterophils, H/L ratios

Pulse Analysis

Biomarkers such as complete blood counts and oxidative‑stress indices are essential tools for assessing poultry health, yet geese have received comparatively little scientific attention. This study fills a notable gap by providing a comprehensive profile of hematological and oxidative parameters in Turkish geese, stratified by age and sex. By establishing baseline values, the research equips veterinarians and farm managers with a diagnostic framework that can differentiate normal physiological variation from disease‑related changes, a critical step for early‑stage intervention in commercial operations.

The findings underscore age as the dominant factor shaping blood and immune profiles. Young birds exhibited elevated erythrocyte numbers and hematocrit, reflecting robust oxygen‑transport capacity, while adults showed increased leukocyte counts, heterophil percentages, and higher heterophil‑to‑lymphocyte ratios, markers often linked to stress and infection risk. These age‑related shifts suggest that management practices—such as vaccination timing, nutrition adjustments, and environmental controls—should be tailored to the developmental stage of the flock to mitigate disease susceptibility and optimize growth performance.

Beyond immediate farm applications, the study’s insights into oxidative‑stress dynamics have broader implications for avian nutrition and breeding strategies. The higher total oxidant status observed in females points to potential sex‑specific nutritional requirements, perhaps warranting antioxidant‑rich feed additives to balance oxidative load. Moreover, the stable total antioxidant status across ages indicates an inherent capacity that could be leveraged in selective breeding programs aimed at resilience. Future research might explore how dietary interventions or environmental enrichment influence these biomarkers, paving the way for precision‑livestock approaches that enhance both animal welfare and economic returns.
