The article deals with the issues of prevention of trauma to the organs of the reproductive system of cows. The experiment used cows-primates and adult animals during childbirth, for the premature rupture of a productive bladder, when the cervix was not completely opened, because of this, allantois and amnion broke through the birth canal without leaving the outside. All animals on the principle of pair analogues were divided into two groups: experimental and control. Animals of the experimental group of primates used the drug SenseilskWeix in dose 5 ml, and a group of adults and Cor - 10 ml, according to instructions. At the same time, experimental groups of cows-primates and adult cows were injected 40–50 OD oxytocin to increase the contractile function of the uterus after 10–15 after the relaxation of her cervix. In control groups, animals were not given drugs. In the experimental and control groups of cows, the firstborn was selected for 21 goals, and adult cows 39 and 38 goals, respectively. Immediately after birth, obstetric examination of cows was conducted in order to detect traumas of the genital organs obtained during the birth process. In this case, lacerated wounds, hematomas of the vagina, vulva , horse, vagina, cervix were recorded . As a result of the studies, the frequency of traumas of the soft tissues of the canal tract in the experimental and control groups of animals was taken into account, and the correlation of this indicator with the weight of the calf after birth was established. We found that calves weighing 35 and more kg were more often born in adult cows of experimental and control groups at 22.0 and 28.1% respectively. At the same time, we drew attention to the fact that during the birth of large calves in adults trauma to the genital organs of cows was noted at least 19.9% or twice in the experimental group and 7.3% in the control group. This indicates a slight progress in the birth process and better preparedness of adult cows for calving. Similar data were obtained from experimental and control cows at calves weighing less than 35 kg. At the same time, in experimental groups traumas of the birth canals were registered twice as often in primary cows as in comparison with adult animals, and in control groups 2.3 times, respectively. In the control group of primary cows, the frequency of trauma to the birth canal was 1.35 times or 14.3% higher compared with the experimental animals. Depending on the weight of the calf during birth, this difference was greater by 21.7% or 2.1 times, and at birth calves weighing less than 35 kg and 8.0% or 1.2 times, and – weighing more than 35 kg. In the group of first-born cows during the genera, the frequency of trauma to the birth canal more depends on the size of the fetus at birth, and the use of the drug SenseilskWeix reduces her more than twice the birth of calves weighing less than 35 kg and 1.2 times - and with a mass of calves more than 35 kg. In the control group of adult cows, trauma to the birth canal was noted 2.05 times more often than in the experimental one. The genital organs of the experimental group of cows were traumatized 1.8 times and less frequently compared with the control group at birth of calves weighing up to 35 kg, and at birth of calves more than 35 kg this figure was increased to 2.2 times. Analyzing the incidence rate of trauma in adult cows, depending on the number of animals in the experimental and control groups, we established its dependence on the size of the fetus at birth. At birth, calves weighing more than 35 kg in the control group observed an increase in the trauma of the canal of the cows by 13.5% compared with the animals of the experimental group.
