Abstract

Hematologic and plasma biochemistry parameters of barn owls (Tyto alba) were studied in collaboration by the Exotic Division of the Faculty of Veterinary Science of the Szent Istvan University and the Eötvös Loránd University, both in Budapest, Hungary. Blood samples were taken from a total of 42 adult barn owls kept in zoos and bird repatriation stations. The following quantitative and qualitative hematologic values were determined: packed cell volume, 46.2 ± 4%; hemoglobin concentration, 107 ± 15 g/L; red blood cell count, 3.2 ± 0.4 × 1012/L; white blood cell count, 13.7 ± 2.7 × 109/L; heterophils, 56.5 ± 11.5% (7.8 ± 2 ×109/L); lymphocytes, 40.3 ± 10.9% (5.5 ± 1.9 × 109/L); monocytes, 1.8 ± 2.1% (0.3 ± 0.3 × 109/L); eosinophils, 1 ± 1% (0.1 ± 0.1 × 109/L); and basophils, 0.6 ± 0.5% (0.1 ± 0.1 × 109/L). The following plasma biochemistry values also were determined: aspartate aminotransferase, 272 ± 43 U/L; l-γ-glutamyltransferase, 9.5 ± 4.7 U/L; lipase, 31.7 ± 11.1 U/L; creatine kinase, 2228 ± 578 U/L; lactate dehydrogenase, 1702 ± 475 U/L; alkaline phosphatase, 358 ± 197 U/L; amylase, 563 ± 114 U/L; glutamate dehydrogenase, 7.5 ± 2.5 U/L; total protein, 30.6 ± 5.3 g/L; uric acid, 428 ± 102 µmol/L; and bile acids, 43 ± 18 µmol/L. These results provide reliable reference values for the clinical interpretation of hematologic and plasma biochemistry results for the species.

Intervalos de referencia hematológicas y de bioquímica plasmática de lechuzas comunes adultas sanas (Tyto alba).

Se estudiaron los parámetros hematológicos y de bioquímica plasmática de lechuzas comunes o también llamadas de campanarios (Tyto alba) con la colaboración de la División de Animales Exóticos de la Facultad de Ciencias Veterinarias de la Universidad Szent Istvan y de la Universidad Eötvös Loránd, ambas localizadas en Budapest, Hungría. Las muestras de sangre fueron tomadas de un total de 42 lechuzas adultas que se encontraban en zoológicos y en estaciones de refugio de aves. Se determinaron los siguientes valores hematológicos cuantitativos y cualitativos: volumen de hematocrito, 46.2 ± 4%; concentración de hemoglobina, 107 ± 15g/L; recuento de glóbulos rojos, 3.2 ± 0.4 × 1012/L; recuento de glóbulos blancos, 13.7 ± 2.7 × 109/L; heterófilos, 56.5 ± 11.5% (7.8 ± 2 × 109/L); linfocitos, 40.3 ± 10.9% (5.5 ± 1.9 × 109/L); monocitos, 1.8 ± 2.1% (0.3 ± 0.3 × 109/L); eosinófilos, 1 ± 1% (0.1 ± 0.1 × 109/L) y basófilos, 0.6 ± 0.5% (0.1 ± 0.1 × 109/L). También se determinaron los siguientes valores bioquímicos plasmáticos: aspartato aminotransferasa, 272 ± 43 U/L; L-γ-glutamil transferasa, 9.5 ± 4.7 U/L; lipasa, 31.7 ± 11.1 U/L; quinasa de creatina, 2228 ± 578 U/L; lactato deshidrogenasa, 1702 ± 475 U/L; fosfatasa alcalina, 358 ± 197 U/L; amilasa, 563 ± 114 U/L ; glutamato deshidrogenasa, 7.5 ± 2.5 U/L; proteína total, 30.6 ± 5.3 g/L; ácido úrico, 428 ± 102 µmol/L y ácidos biliares, 43 ± 18 µmol/L. Estos resultados proporcionan valores de referencia confiables para la interpretación clínica de resultados hematológicos y de bioquímica plasmática para dicha especie.
