Plasma Biochemical Parameters of The Blood of Captive Adult Male and Female Black-Necked Pheasants (Phasianus colchicus), Gray Partridge (Perdix perdix) and Chukar Partridge (Alectoris chukar) in Bulgaria

Blood samples were collected from 36 (12 by species; 6 male and 6 female) captive, adult, clinically healthy Black-necked pheasants or Southern Caucasus pheasants (Phasianus colchicus), Gray partridge (Perdix perdix) and Chukar partridge (Alectoris chukar) for plasma biochemical analyses. The investigated parameters were Total protein, Albumin, Total bilirubin and Glucose. Significant differences (P<0.05) among both sexes were found in concentrations of total bilirubin and Glucose in Gray partridges; and Total protein in Chukar. In female Gray and Chukar partridges, the Total protein values were higher than in male ones, but in pheasants it was the opposite. The trend for Albumin and Total bilirubin values in the three game birds were inverted, with higher values observed in male than female birds.
