A total of 20 apparently healthy adult Muscovy ducks (10 birds per sex) reared on scavenging system were used for the study. Two sets of blood samples were collected from each duck at point of sacrificing and analysed for haematological and electrolyte constituents. The result showed that sex did not significantly (P>0.05) influence all the parameters studied with values that were comparable to other works. The overall mean haemato-biochemical values from this study were 2.00x10 12 /L (red blood cell), 35.85% (packed cell volume), 19.24 g/dL (haemoglobin), 98.43pg (mean corpuscular haemoglobin), 57.21 g/dL (mean corpuscular haemoglobin concentration), 187.38 fL (mean corpuscular volume), 132.00x10 9 /L (platelets), 14.56x10 9 /L (white blood cell), 43.55% (heterophils), 1.85% (eosinophils), 52.55% (lymphocytes), 2.05% (monocytes), 0.92 (heterophil/lymphocyte ratio), 2.16mg/dL (calcium), 157.00 mmol/L (sodium), 7.87mmol/L (potassium), 112.17mmol/L (chloride), and 9.37 mg/dL (phosphate). Therefore, the haematological and electrolyte constituents of the scavenging Muscovy ducks studied in comparison with available literature on healthy ducks possibly indicated normal health and low stress status of the birds.

Comparative biometric measurements (weight, length, width and thickness) of their liver organs were also done. Total protein and albumin were significantly (P<0.05) higher in female ducks than in males while ALT, AST ALP and total bilirubin were unaffected (P > 0.05) by sex. The biometric measurements of the liver of Muscovy ducks according to sex were significantly (P < 0.05) higher in males than females. Liver biometric measurements according to lobation were significantly (P < 0.05) higher in the right lobe than in the left lobe, particularly, in terms of liver lobe weight and length of both sexes of ducks while liver lobe width and thickness were statistically similar (P > 0.05) in both sexes. Therefore, sex had a significant influence on serum total protein and albumin, as well as the biometric measurements of the liver of Muscovy ducks studied.

Mean±SD of all the measured traits were significant (P<0.05) across the different age groups. Pearson's coefficients of correlation among the measured traits were all highly significant (P<0.01) and ranged from 0.9-0.63. Using varimax rotation of the transformation matrix, two Principal Components (PC) were extracted which total 89.14% of the total variance. PC1 accounted for 86.49% of the total observed variance and was loaded by; wither height, rump height, neck length, foreleg length, hind-leg length, scrotal length, ear length, tail length and face length which describes the overall body size. While PC2 contributes 2.64% of the total observed variance and had its loading (rump length, body length, neck circumference, abdominal circumference, scrotal circumference and top-line) for meatiness. The results suggest that PCA could be explored in breeding programs with greater success to eliminate variable redundancy.
