Plasma Protein Fractionation by Electrophoresis and Albumin/Globulin Ratio of the Pintail (Anas acuta)

Plasma protein electrophoresis was performed on 25 males and 25 female Pintails (Anas acuta) captured in the wild, and albumin and globulin fractions and albumin/globulin ratio (A/G) were obtained as the reference value of this species. The proportion of the albumin fraction in the protein was high (49.18±5.43%) and the prealbumin fraction was present (20.40±4.03%). The ratio of α1-, α2-, and β- and the γ- globulin fractions was 2.84±0.58%, 4.23±0.91%, 21.10±2.81% and 2.25±0.95%, respectively. The A/G ratio (2.33±0.40) determined by electrophoresis was higher than that obtained through blood chemistry using BCG method (0.38±0.03). Plasma protein electrophoresis and the A/G ratio determined through this method are useful for monitoring the physical conditions of wild Pintails.
