Abstract

Reproduction is a crucial issue at the present stage in the pig husbandry development. Infertility of breeding sows leads to excessive use of feed, increased costs associated with failed inseminations, insufficient breed and early culling of sows. Aim of the research. Study of infertility types and prevention of postpartum diseases in sows in order to develop methods to control them. Methods. A two-stage experiment was carried out in 2019–2020 at the LLC "Ryasnyanske" farm in Sumy region, Ukraine. The first stage involved development of a method for prevention and control of infertility in sows. The second stage focused on the method of postpartum pathology prevention. Results. The conducted research established that surfagon and vitamins manifested the highest efficiency in case of alimentary infertility as they increased fertilization by 20.8 %. In terms of symptomatic infertility, the best results were achieved through a combined use of surfagon and gonadotropic hormone for both primary and multiple fertilization of sows, especially considering extremely low values in the control group - 15 % and 6.5 % of piglets, respectively. Aminazine proved to be the most effective remedy for immune infertility, the obtained results were 17.2 % higher than in the control group. Surfagon at a dose of 5 ml together with estrofan twice a day fully prevented inflammatory postpartum pathologies in sows. Conclusions. Pathologies of the reproductive organs in sows are widespread at pork-producing farms. Individual use of surfagon was justified for treatment of alimentary, symptomatic and immune infertility of sows and prevention of postpartum pathologies. A combined use of tissue therapy and biologically active drugs proved to be the most effective. The treatment regimens described above reduce infertility and prevent postpartum pathologies in sows.

RELEASING HORMONE AND VITAMIN productive cycle for 25–30 daysProductivity of pig-breeding farms mostly depends on the frequency of using breeding stock and the reproductive potentialEFFICIENCY IN THE TREATMENT OF OBSTETRIC AND GYNECOLOGICAL PATHOLOGIES IN BREEDING SOWS after weaning
After tetravit administration for alimentary infertility, the fertilization percentage in relation to the total number of animals in the groups exceeded the control by 20.8 %, after tissue therapy, the first and third groups showed a percentage which is higher by 39.0 % indicating a significantly higher efficiency of surfagon in comparison with vitamins
The data obtained on the basis of treatment of sows with symptomatic infertility, differ significantly from those with alimentary infertility

RELEASING HORMONE AND VITAMIN productive cycle for 25–30 days. Productivity of pig-breeding farms mostly depends on the frequency of using breeding stock and the reproductive potential. All the animal studies follow ARRIVE guidelines and have been performed according to the of sows. At the site of insemination, 6.4 % of the main sows and 1.9 % of tested ones showed signs of anaphrodisia, which appeared for suppression of the reproductive cycle in sows due to alimentary and symptomatic infertility, fertilization disruptions due to an increased sperm antibody titer, which is characteristic of the immune infertility [1, 2]. Frequent postpartum genital diseases eventually cause infertility in sows and insufficient quality and quantity of young animals [4]
