This study was conducted to examine the effect of the intramuscular administration of Menotropin on the blood profile and internal organ dynamics of mature Nigerian Indigenous cocks during spermatogenic stimulation. 72 mature Nigerian indigenous cocks were randomly divided into 4 groups of 18 cocks in a completely randomized design (CRD) experiment. Varying doses of Menotropin at 0.0mL, 0.10mL, 0.20mL, and 0.30mL, representing T1, T2, T3 and T4, respectively were administered. At the start of the experiment, the red blood cell (RBC) ranged from 4.10–5.07x106mm3, packed cell volume (PCV) ranged from 36.60 to 40.05%, the haemoglobin ranged from 11.30 to 12.20g/dl, White blood cell (WBC) 214.06-240.73x103mm3, Platelet 128.00-157.00x109/l, Mean Corpuscular Volume (MCV) 128.56-158.56fl, while mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) ranges from 25.39-33.00pg and 31.00-32.75g/dl, respectively. At the end of the experiment, RBC, haemoglobin, platelet, and MCV showed significant improvement (p < 0.05) across the treatment groups; while the PCV, WBC, and MCHC significantly reduced (p<0.05) compared with the control group. At the start of the experiment, total protein ranges from 3.80 to 4.60g/dl, albumin 2.25 to 3.30g/dl, urea and cholesterol ranged from 9.65 to 12.30mg/dl and 121.50 to 138.00mg/dl, respectively. At the end of the trial, the total protein, albumen, and cholesterol values were significantly (p < 0.05) reduced, while the urea significantly (p<0.05) increased. The results indicated that apart from MCH, globulin, glucose, and creatinine, other haematological and serum biochemical parameters of mature Nigerian indigenous cocks may be affected by exogenous treatment with FSH and LH above 0.10ml. Increasing the Menotropin up to 0.20mL had deleterious consequences on the kidney and gallbladder. Although the values obtained fall within the normal range for chicken, the variations observed in the blood parameters suggest the need to constantly and closely monitor the blood profile of Nigerian indigenous cocks during treatment with exogenous FSH and LH to avoid deleterious consequences on the blood profile and internal organs.
