| description | The evaluation of reproductive qualities of mares is an important element of horse breeding technology. Histological analysis of the endometrium provides information about the mare’s ability to conceive and carry a pregnancy to term. The article presents the results of histological studies of the endometrium in mares of <10 (n=6) and ≥10 (n=13) years old (yо). Two morphometric parameters were used for the analysis: diameter (GDm) and density (GDs) of endometrial glands in diestrus phase of the cycle. There was noted an increase in GDm (20.5 - 62.9 μm, p<0.001) and a decrease in GDs (16.6 - 10.9 units per field of view (ufov), p<0.1) in the endometrium of mares older 10 yo. An endometrial index EI (GDm / GDs, μm/ufov) characterizing the functional state of the endometrium has been proposed. The results of pregnancy rate and the level of life foal birth in mares after histological studies were analyzed. A significant relationship EI with age (p=0.0133) and fertility (p=0.0059) of mares was established. Among mares with EI< 3 µm/ufov only one mare was older than 10 years and all the mares had foaled successfully. The mares with EI>3 µm/fov were older than 10 years and had problems with conception and gestation. In our studies, EI in the range from 3 to 6 µm/ufov could be interpreted as reversible state of the endometrium and after correct treatment it is possible to increase the fertility of mares. |
