The present study was conducted to evaluate the status of hemato-biochemical indices in Vanraja birds during different seasons from southern Bihar, India. For this study, a total of 50 bisexual Vanraja birds were randomly selected for three different seasons viz. summer, autumn, and winter. Haematological parameters, including Total erythrocyte count (TEC), Packed cell volume (PCV), Hemoglobin (Hb), Mean corpuscular value (MCV), Mean corpuscular hemoglobulin (MCH), Total leukocyte count (TLC), and Differential leukocyte count (DLC), were measured using standard laboratory techniques. Biochemical parameters such as total protein, albumin, glucose, urea and creatinine levels were also analysed. Statistical analysis revealed significant variations in several hematobiochemical parameters across seasons. Notably, TEC count, Hb concentration, and PCV were highest in winter, while TLC count showed a non-significant change during different seasons. Biochemical parameters such as glucose levels were higher in winter, while albumin levels were elevated in autumn followed by summer and winter. These findings highlight the importance of considering seasonal variations in the management and husbandry practices of Vanraja birds to optimize their health and productivity. Understanding these seasonal changes is essential for sustainable poultry production and can aid in the development of strategies to mitigate the potential impacts of environmental fluctuations on Vanraja bird populations. Further research is necessary to elucidate the underlying mechanisms driving these seasonal variations in hematobiochemical parameters.
