[Effect of hysterectomy in swine on health status and various indicators of peripheral blood. I. Clinical observations].

Studies were carried out on 36 sows from 100-250 kg of body weight, divided into 5 groups. The sows of group I were given Stresnil and Vetbutal to examine the effect of the anesthetics used during operation on the health condition of the animals studied in the other groups. Laparotomy was performed in group II, amputation of unpregnant uterus in group III, amputation of pregnant uterus or several hours after delivery in group IV, and amputation of pathologically changed uterus by the intraabdominal method and of fallen out uterus after delivery by the extra-abdominal method in group V. It was found that laparotomy, amputation of unpregnant uterus and that several hours after delivery were not a serious danger to the life of pigs, but general disturbances occurring after the operation depended on the magnitude of the operational trauma and health condition before operation. The treatment of pathologically changed uterus by intraabdominal amputation gave positive results in 69.2% of cases. However, no positive results were obtained in the treatment of fallen out uterus after delivery by extraabdominal amputation.
