Changeable hawk eagles (Nisaetus chirratus) are abundantly kept in sanctuary in which no haematologic reference is ever reported. This study aimed to present the visual keys and morphometric references of changeable hawk eagles’ blood cells as the standard for further haematologic count. The peripheral blood smears were prepared and collected from eight changeable hawk eagles kept at Wildlife Rescue Centre Jogja then stained with 10-fold diluted Giemsa stain following the standard manners. All slides were inspected and captured under camera-equipped microscope which then were morphologically and morphometrically evaluated using ImageJ version 1.52a. As the changeable hawk eagles are naturally present in dark and bright morph, we statistically compared the blood cells morphometric parameters between morph-based groups. Change...

Information related to the histologic description of various bird species' digestive organs based on their diet and its significance is yet limited. This study aimed to present a descriptive explanation of gastrointestinal organs of a changeable hawk-eagle (Nisaetus cirrhatu) and oriental honey buzzard (Pernis ptilorhynchus) as carnivorous, a southern cassowary (Casuarius casuarius) as an omnivorous, and a domestic chicken (Gallus gallus) as granivorous. In the current study, proventriculus (glandular stomach) and intestinal segments were microscopically examined and compared to understand the special histological features among avian species due to their important roles to digest the ingesta. The dissected specimens were preserved in 10% non-buffered formalin, then were processed throug...

Half of the world’s bird species are monomorphic, where male and female are difficult to distinguished morphologically, including cockatoos. Sex identification using molecular bird sexing is more accurate and applicable because it directly targets the sex chromosomes. The purpose of this study was to determine the sex of Sulphur‐crested cockatoo (Cacatua galerita) by detecting differences in the intron size of the chromodomain helicase DNA‐binding 1 (CHD1) gene on the Z and W chromosomes by polymerase chain reaction (PCR) method and to compare of plucked feathers and blood samples as DNA sources for molecular bird sexing. DNA was extracted from feather and blood samples from four C. galerita. Extracted DNA was amplified on the CHD1 gene by PCR method with P2, MP, and NP primers, which were visualized using agarose gel 1.5% under UV transilluminator with a wavelength of 280 ...

Annually, we perform general raptor examination involving conventional routine hematologic examination. However, low sample quality and over dense blood cell population during total erythrocyte and leukocyte counting were deemed as obstacles. This study aimed to give wider insight in how total erythrocyte and leukocyte counting was performed at WRC Jogja to overcome those obstacles. Firstly, handling and restraint were done physically adapting the Aba method. One-to-two half millilitres of blood was collected from the ulnar vein using 3-ml-syringe with 24-gauge-needle which was then preserved in an EDTA-containing tube and proceeded to subsequent method no more than 3 hours after collection. No hypovolemic shock was observed. During total erythrocyte and leukocyte counting using Neubauer-ruled counting chamber, we modified the dilution factor to be 250-fold and 50-fold respectively. This method yi...

A method of sex determine in monomorphic birds is by molecular sexing which is based on the PCR amplification of the chromodomain helicase DNA-binding 1 (CHD-1) gene of the bird sex chromosome. This study was aimed to sex determine of the C. sulphurea by amplifying the CHD-1 gene on the Z and W chromosomes and comparing the PCR amplification results from peripheral blood and plucked feathers samples. The samples used were four birds of C. sulphurea from the Wildlife Rescue Centre (WRC), Yogyakarta. The feathers obtained from the ventral wings of each bird were plucked. Through the cutting of the birds' nails, the peripheral blood samples were collected into microhematocrit tubes which contained Heparin. The amplification of the CHD-1 gene used the PCR method with specific primers, such as NP, ...

Metode ini telah diterapkan pada berbagai pemeriksaan klinis yang melibatkan inspeksi morfologi sel seperti pemeriksaan sitologi, histopatologi, dan patologi digital. Kalibrator skala yang umum digunakan adalah mikrometer kalibrasi (calibration slide). Terbatasnya ketersediaan mikrometer kalibrasi di laboratorium sering menjadi hambatan dalam melakukan morfometri sel sehingga diperlukan alat alternatif yang terbukti memiliki akurasi yang sama. Tujuan penelitian ini adalah membandingkan parameter morfometri eritrosit elang ular bido (Spilornis cheela) menggunakan tiga kalibrator berbeda: mikrometer kalibrasi, kamar hitung Neubauer, dan batang skala digital pada kamera mikroskop. Sebanyak 58 eritrosit elang ular bido dipilih dari preparat apus darah yang diwarnai dengan pewarna Giemsa dan difoto menggunakan kamera mikroskop. Seluruh sel diukur menggunakan aplikasi ImageJ.

This work used five C. goffiniana birds which were collected from the Wildlife Rescue Center (WRC) in Pengasih, Kulon Progo, Yogyakarta. From each C. goffiniana , feather samples were collected by plucking feathers on the ventral wing and peripheral blood samples were taken by cutting their nails and collecting the blood into microhematocrit tubes containing heparin. The next stage was DNA extraction and DNA amplification on the CHD-1 gene using the PCR method by NP, P2, and MP primer pairs. Then, products of DNA extraction and PCR amplification were electrophoresed on 1.5% agarose gel and visualized under a UV light transilluminator with a wavelength of 260 nm. ...
