Providing assistance to highly productive sows in case of labor disorders

Pathological childbirth in highly productive sows is a critical condition associated with high risks for piglets and the mother herself. The purpose of this work was to study the prevalence of pathological childbirth in highly productive sows and to find an effective method of providing assistance in case of labor weakness. The object of the study was a hybrid breeding stock of pigs (large white× landrace) and the offspring obtained from them. The research was conducted on the basis of an industrial pig breeding enterprise. The prevalence of pathological childbirth was studied in 510 repair and basic sows. In order to develop an effective method of obstetric care for weak labor, a comparative assessment of different methods was carried out. Animals were diagnosed with: in the first group, a manual method of delivery was used; in the second group, oxytocin was injected intramuscularly at a dose of 40 ME; in the third group, 20 ME of oxytocin were injected intramuscularly (at the beginning of labor, all sows were injected intramuscularly with calcium borgluconate at a dose of 20 ml); The fourth group was simultaneously injected intramuscularly with 20 ml of calcium borgluconate and 20 ME of oxytocin; the fifth group was injected intramuscularly with calcium borgluconate at a dose of 20 ml and Uterotone with the active ingredient propanolol hydrochloride at a dose of 5 ml. It has been established that the main cause of pathological childbirth in highly productive sows is weak contractions and struggles, as well as the incorrect location of the fetus in relation to the birth canal of the female. The clinically justified and most effective method of correcting labor weakness with an interval between the birth of piglets of more than 30 minutes is combined intramuscular administration of calcium borgluconate at a dose of 20 ml and oxytocin at a dose of 20 ME. This scheme helps to restore the coordinated contractile activity of the myometrium and minimize the risks of perinatal loss of offspring.
