Abstract
Lots of valuable medical information of avian species can be obtained from hematology and blood biochemistry such as nutritional status, physical condition and also the diagnosis of diseases. Studies of blood chemistry and hematology are the most important database for wildlife rescue and conservation. However, this kind of studies for endemic species in Taiwan is rare.
Collared Scops Owl（Otus bakkamoena）is one avian species living closely to people and listed on the Wildlife Conservation Law as a rare and valuable species in Taiwan (Wildlife conservation law, 2009). The wild population of this owl keeps declining due to nature habitat destruction. Collared Scops Owls are the major species of raptor rescued cases in wildlife rescue centers around Taiwan. The aim of this study is to establish the hematologic and biochemical references with protein electrophoretic fractions in clinically healthy Collared Scops Owls.
Blood samples were taken from the brachial vein from 25 subadults, 21 adult males, and 15 adult females. Hematologic values included packed cell volume（PCV）, hemoglobin（Hb）, red blood cell（RBC）count, white blood cell（WBC） count, and leukocyte differential count. Biochemical analyses included total plasma protein, albumin, glucose, Gamma glutamyltransferase（GGT）, Lactate dehydrogenase （LDH）, Aspartate aminotransferase（AST）, cholesterol, Creatine kinase （CK）, uric acid, calcium, phosphorus, Sodium, Chloride and potassium concentrations together with protein electrophoretic fractions.
Adults had higher levels of PCV, Hb, H/L ratio, total protein, albumin, cholesterol, A/G ratio, Na and Cl than subadults. Subadults had higher levels of phosphate concentration than adults. Subadults and adults had different levels of GGT. Females had higher levels of AST than males but not significantly. However, body condition index had no effects on these analyses. Morphology of blood cells from the Collared Scops Owls are similar to other Strigidae owls. Lymphocytes and heterophils are the most abundant cellular type.
The results of the hematological and biochemical reference values and protein electrophoresis presented in this study can be directly used in the clinical veterinary medicine and wildlife conservation in this species. This established research model of avian clinical pathology also contributed to the future work of other endemic avian species in Taiwan.
