Influence of Dietary Turmeric Powder (Curcuma longa) Supplementation on Blood Haematological Parameters of Kuroiler Chicks

This study investigated the physiological impact of incorporating varying levels of turmeric powder (Curcuma longa) specifically focusing on haematological parameters of Kuroiler chicks. For this trial, 120 day-old chicks, selected for uniform body weight from a single batch, were distributed across four experimental groups. The control group T0 received a standard basal diet following BIS (2007) guidelines, while the treatment groups- T1, T2 and T3 were supplemented with turmeric powder at dosages of 5.0 g/kg, 7.5 g/kg, and 10.0 g/kg, respectively. Each treatment comprised 30 chicks, further divided into the three replicates of 10 chicks each. Following an 8-week feeding period, hematological analysis was conducted on representative blood samples from each chick to determine hemoglobin (Hb) levels, packed cell volume (PCV), total RBC, total WBC and including differential WBC counts for lymphocytes, neutrophils, monocytes and eosinophils. Statistical analysis revealed that the significant (P≤0.05) increase in haemoglobin concentration, total RBC and lymphocytes counts was observed in the T2 group (supplemented turmeric powder at 7.5 g/kg) compared to all other experimental groups. These findings suggest that inclusion of dietary turmeric powder @ 7.5 g/kg positively influenced the haemoglobin concentration, total RBC and lymphocytes counts in Kuroiler chicks.
