TO THE QUESTION OF THE TECHNIQUE OF ENDOMETRIAL BIOPSY IN COWS

Abstract

The article presents the results of studies of morphometric parameters of the reproductive system in cows. It was found that the diameter of the left horn in the bifurcation area significantly exceeds the diameter of the right horn of the uterus. The length of the uterus sections is 28.53% (left) and 29.68% (right) in relation to the total length of the egg ducts. The length of the uterine horns is 34% (left) and 32.52% (right), the body of the uterus is 6.53%, the neck is 2.31%, the vagina is 28.63% - 28.8%. The length of the left ovipositor in cows is less than the right ovipositor by 9.69%, and the length of the left uterine horn exceeded the indicator in the right by 9.53%. The diameter of the left egg duct is expanded in the caudal direction. The right ovipositor is narrowed in the medial area, and has no significant differences in width in the cranial and caudal parts. In the caudal direction, the diameter of the uterine horns increases. At the same time, the width of the left uterine horn is greater than the width of the right one in the middle by 7.33%, and in the caudal by 4.43%. The body and cervix are rectangular in shape. The widest part of the vagina is cranial. The vagina narrows in the caudal direction. The thickness of the wall of the horns and the body of the uterus is uneven. Areas with a thinner wall predominate. The mucous, submucosal and muscular layers of the left uterine horn are inferior by 21.97%, 33.3% and 20.79% to the corresponding indicators in the right uterine horn.
