- Abstract
The study was conducted on 40 Harderian glands obtained from 20 (10 male and 10 female) adult clinically healthy Mongolian pheasants. The glands were weighed and measured before placement in fixation fluids. Permanent histological preparations were prepared from fixed glands using conventional techniques. Histometric studies of all microstructural elements of the glands were done with a light microscope with a built-in eyepiece micrometer. The histometric analysis showed that the average size of pheasant Harderian gland lobules was 285.42 µm. The average outer diameters were as followed: acini - 46.24 µm, secretory ducts - 48.73 µm, lobular ducts - 167.96 µm and gland excretory ducts - 272.28 µm. The histometric investigation of 13 microstructural elements of the gland allowed concluding that by the time of the commercial realisation of Mongolian pheasants, the Harderian gland was a structurally and functionally complete organ.
