ABSTRACT
The objective of the work has been to study the contraction of uterine muscles in cows during the placenta stage and the postpartum period. For the first time, a new device for determining uterine contractions has been used to study the strength, duration, and frequency of uterine contractions to diagnose early signs of postpartum disease in the uterus. The experimental part of the work was carried out based on the farms of agrofirm “Kolos”, LLC in the Tetyush district of the Republic of Tatarstan and MBS “Zhaiyk” in the Akzhaik district of the West Kazakhstan region of the Republic of Kazakhstan. The contraction activity of the uterine muscles after fetal excretion was studied by means of a device for determining uterine contractions, which consisted of a pressure rubber ball, discharge valve, manometer, handle, rubber tube, catheter, rubber camera, and rubber camera pin. Thirty minutes after fetal excretion, a 0.1 kPa decrease in uterine contraction strength and a 0.96 min reduction in the duration of the uterine contractions resulted in the retained placenta, while a 0.91 kPa decrease and a 0.37 min reduction in 10 min after the placenta expulsion in cows resulted in subinvolution of the uterus and postpartum endometritis. The device for determining uterine contractions allows for early diagnosis of uterine abnormalities in the placenta stage and the postpartum period.
