The study aimed at determining the effect of Jatropha tanjorensis leaf meal on the haematology and serum biochemistry of broiler birds. A total of 132 unsexed two weeks old broiler chicks were randomly divided into four groups of thirty-three broilers each, with 11 birds per replicate. The four experimental diets were formulated to contain 0, 1.5, 3.0, and 3.5% dietary supplementation of Jatropha tanjorensis leaf meal, respectively. The groups were randomly assigned to the four experiment diets (T1, T2, T3 and T4) at 3 replicates for 10 weeks in a completely randomized design. At the start of the experiment, the haemoglobin ranged from 6.82 to 7.40g/dl, packed cell volume (PCV) ranged from 24.30 to 28.56%, red blood cell (RBC) 2.46–2.63x106mm3, White blood cell (WBC) 33.20-34.01x103mm3, Mean Corpuscular Volume (MCV) 81.00-86.05fl, while mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration ranges from 24.11-23.24pg and 17.98-19.01g/dl, respectively. At the end of the experiment, haemoglobin, PCV, RBC, WBC and MCV showed significant improvement (p < 0.05) across the treatment groups, while MCH and MCHC significantly reduced (p < 0.05). At the start of the experiment, total protein ranges from 3.62 to 4.20g/dl, albumin 2.12 to 2.89g/dl, globulin 1.04 to 1.65g/dl, cholesterol and glucose ranged from 83.67 to 86.59mg/dl and 161.67 to 162.05mg/dl, respectively. At the end of the trial, total protein, albumen, and globulin values were significantly (p < 0.05) higher in T3 and T4. Cholesterol and glucose was significantly reduced (p < 0.05) from T1 to T4. The study revealed that the supplementation of Jatropha tanjorensis leaf meal in broiler diets had no deleterious effect on these haematological and serum biochemical parameters of broilers and could be supplemented in broiler diets up to 3.5%.
