MORPHOLOGY OF OVIDUCTS OF EUROPEAN LOWLAND BISON BISON BONASUS BONASUS (L. 1758)

摘要

The female genital organs of European bison has not been thoroughly investigatedthus far. The aim of the present study was to describe the macroscopic and microscopicstructure of oviducts in European bison and their changes throughout postnatallife. As the material served genital organs of 55 European bison females. Animalswere divided into two age groups. The first included 36 sexually immature femalesat the age of 2 months to 1.5 year, whereas the other counting 19 cows includedsexually mature females at the age of 2 to 20 years. The morphological analysisof isolated oviducts were performed. The basic morphometric and micrometric parameterswere measured. It was stated that oviducts of bison females reach developmentalmaturity at the age of 1.5–2 years. The morphology and histological featuresof oviducts resembles that of domestic cattle, however their dimensions differ.
