Source and sex effects on the total blood protein and its various fractions were studied using juvenile West African Dwarf goats derived from Southern Nigeria. The goats were sourced from three distinct towns in the humid tropics namely, South-East (Umuahia), South-South (Ugheli) and South-West (Akure) at the rate of 6 males and 18 females per location. The mean values of the total blood plasma protein and its fractions obtained for the WADGs from different zones are 10.01±0.07 g/100ml, 10.07±0.08 g/100ml and 10.16±0.35 g/100ml (total plasma protein); 9.62±0.10 g/100ml, 9.68±0.08 g/100ml and 9.68±0.09 g/100ml (total serum protein), 0.38±0.03 g/100ml, 0.39±0.01 g/100ml, and 0.38±0.04 g/100ml (plasma fibrinogen), 5.62±0.23 g/100ml, 5.78±0.24 g/100ml and 5.45±0.26 g/100ml (serum albumin), 4.00±0.19 g/100ml, 3.89±0.29 g/100ml, and 4.12±0.25 g/100ml (serum globulin), and 1.41±0.27, 1.49±0.15 and 1.34±0.12 (albumin/globulin ratio) for the goats from South-East (Umuahia), South-South (Ugheli) and South-West (Akure) respectively. The studies also indicate that albumin accounts for 53-58% of the total serum protein; globulin accounts for 42-47% serum protein, and the plasma fibrinogen 3.6-4% of the total plasma protein. sex and source interaction had no significant (P>0.05) effects on serum proteins; plasma fibrinogen is sex dependent, and the source of goat affects the proportions of the serum albumin, globulin, and albumin/globulin ratio characteristics of the experimental goats.
