Abstract
ABSTRACT The morphometric parameters of erythrocytes in Mandarin ducks- Aix galericulata have never been subjected to study even though this species is common in aviculture. The aim of this study is to investigate the morphometric parameters of erythrocytes in juvenile Mandarin ducks. A total of 1500 erythrocytes obtained from thirty Mandarin ducks were analysed. The smears of the peripheral blood were stained using Diff-Quik® stain method, and the length and width of erythrocytes were measured using ImageJ program. The average length of the measured erythrocytes was 11.879 µm. The maximal measured length of the erythrocytes was 16.049 µm, and the minimal measured length was 5.668 µm. The average width of the measured erythrocytes was 6.160 µm. The maximal measured width of the erythrocytes was 10.115 µm and the minimal measured width was 3.750 µm. In conclusion, knowing morphometric parameters of Mandarin duck erythrocytes is the first step in evaluation process of erythrocytes’ functional state and health condition of an individual.
Highlights
Several studies have described morphometric parameters and hematological characteristics of non-domestic Anseriformes, including: three species of geese (Williams & Trainer, 1971), canvasback duck Aythyavalisineria (Kocan & Pitts, 1976), Pacific black duck Anas superciliosa (Mulley, 1979), Australian wood duck Chenonettajubata (Mulley, 1980) and mallard Anas platyrhynchos (Driver, 1981; Fairbrother et al, 1990; Fairbrother & O’Loughlin, 1990; Levengoodet al., 2000)

The study was conducted in January 2018 and the blood smears from juvenile Mandain ducks- Aix galericulata were taken from thirty Mandarin ducks which were six months old at the time
Summary
Several studies have described morphometric parameters and hematological characteristics of non-domestic Anseriformes, including: three species of geese (Williams & Trainer, 1971), canvasback duck Aythyavalisineria (Kocan & Pitts, 1976), Pacific black duck Anas superciliosa (Mulley, 1979), Australian wood duck Chenonettajubata (Mulley, 1980) and mallard Anas platyrhynchos (Driver, 1981; Fairbrother et al, 1990; Fairbrother & O’Loughlin, 1990; Levengoodet al., 2000) These studies have described themorphological characteristics of hematologicalcells. Erythrocytes were ovoid cells with an ovoid nucleus composed of dense chromatin and homogeneous eosinophilic cytoplasm. Mature avian erythrocytes are elliptical and have an elliptical, centrally positioned nucleus (Campbell, 2015). Avian mature erythrocytes are generally larger than mammalian erythrocytes but smaller than reptilian erythrocytes (Sturkie & Griminger, 1986)
