Abstract
The aim is to determine the potential of rectal and ultrasound methods of ex-amination of cow ovaries in the diagnosis of follicular cystic disease.
Materials and methods. The object of the study is infertile Holstein cows of black-and-white breed, owned by Saryagash LLP (Republic of Kazakhstan). 58 ani-mals of 2-3 lactation were selected from 727 dairy cows for gynecological medical examination, the service period of which varies from 130 to 170 days. There are nu-merous unproductive inseminations and signs of anaphrodisia in the anamnesis. During gynecological medical examinations, clinical, rectal and ultrasound methods are used.
Results. Infertility in 79,31 % of cows is caused by follicular cystic disease, which has no specific clinical signs. Rectal palpation revealed pathology in 46 out of 58 cows; it is characterized by painless ovaries, the shape of which is rounded, the size is enlarged; the surface is smooth, but has rounded fluctuating elevations. The ultrasound method confirms the diagnosis in 30 animals. The cysts have clear boundaries, a thin-walled capsule and a size of more than 23 mm; they consist of two or three chambers with anechoicity. With ultrasound in B-mode, the size of cysts, the total area and area of cystic fluid, the total volume of cysts and cystic fluid average 3,30 cm; 17,05 and 26,30 cm2; 100,05 and 68,55 cm3; width of the luteal rim 0,10 to 7,00 mm. A comparative analysis of rectal and ultrasound diagnostics shows that the rectal method is less accurate, while ultrasound is more informative and less traumatic.
