Serum biochemistry and electrophoretic patterns in the Eurasian Buzzard (Buteo buteo): reference values.

Area of Science:

• Avian Medicine
• Veterinary Hematology
• Wildlife Toxicology

Background:

• Hematologic and biochemical reference values for many avian species, including the Eurasian Buzzard (Buteo buteo), are lacking due to data collection challenges.
• This deficit hinders standardized diagnostic approaches, particularly for birds in critical condition.
• The Eurasian Buzzard is a common raptor in Italy, yet its physiological blood parameters remain largely unknown.

Purpose of the Study:

• To determine and establish reference ranges for serum biochemistry and electrophoretic profiles in healthy Eurasian Buzzards.
• To provide a foundation for standardized diagnostic testing in this raptor species.
• To contribute to the advancement of avian laboratory diagnostics.

Main Methods:

• Serum biochemistry and serum protein electrophoresis were performed on blood samples from 40 healthy Eurasian Buzzards.
• Samples were collected from birds undergoing rehabilitation in Italian wildlife rescue centers prior to release.
• Standard laboratory techniques were employed for biochemical analysis and protein fractionation.

Main Results:

• Mean serum biochemistry values included: glucose 375.1 mg/dl, uric acid 7.5 mg/dl, total protein 38.4 g/l, albumin 14.5 g/l, and creatinine 0.1 mg/dl.
• Mean electrophoretic values were: albumin 14.2 g/l, alpha 1 globulin 5.9 g/l, alpha 2 globulin 4.7 g/l, beta globulin 7.5 g/l, and gamma globulin 3.6 g/l.
• Specific enzyme and electrolyte levels were also quantified, providing a comprehensive biochemical profile.

Conclusions:

• This study successfully established key serum biochemistry and electrophoretic reference values for the Eurasian Buzzard.
• These findings represent a significant step towards standardizing diagnostic laboratory investigations in avian medicine for this species.
• The data will be invaluable for wildlife veterinarians and researchers involved in the health assessment and treatment of Eurasian Buzzards.
