“…Therefore, the clinical examination needs to focus on vulvar discharge characteristics, urine characteristics and ultrasound of the urogenital tract. Vulvar discharge can vary in duration, color, consistency, and quantity (Björkman & Grahofer, 2020), but obstetrical intervention and prolonged farrowing have been linked with prolonged, more yellowish and increased amounts of vaginal discharge (Grahofer et al, 2021; Nam, 2020; Waller et al, 2002). Further, prolonged vaginal discharge of more than 5 days, seems to be associated with postpartum disease and reduced subsequent reproductive performance (Björkman et al, 2018; Nam, 2020; Waller et al, 2002).…”

The modern hyperprolific sow is susceptible to metabolic disease and chronic inflammation. The most sensitive phase is parturition, when the sow experiences systemic inflammation and stress, and major changes in metabolism and endocrinology. Resolution of inflammation and stress needs to happen quickly to ensure good reproductive health during puerperium. If the sow fails to adapt to these changes, puerperal disease may occur. The economically most important puerperal disease complex is the postpartum dysgalactia syndrome (PPDS). Other puerperal diseases include infections of the urogenital tract. Diagnosis of PPDS and urogenital disease on‐farm is challenging but several diagnostic methods, including clinical examination, behavioral observations, ultrasonography and biomarkers are available. Ultrasonography is an excellent tool for monitoring the health of the urogenital tract, the mammary gland, and uterine involution and guide further diagnostic interventions. Biomarkers such as Chromogranin A, tumor necrosis factor‐α, and interleukin‐6 represent promising tools to monitor general health and the systemic state of inflammation and oxidative stress of the sow. Nonsteroidal anti‐inflammatory drugs, dopamine antagonists, and oxytocin are promising to address the symptoms of PPDS. Reducing of stress, improving nutrition and intestinal health, and supporting animal welfare‐friendly husbandry help in the prevention of PPDS.

“…There are life history stages where pain is unavoidable, and parturition is one of these times. Modern sows have been heavily selected for reproductive traits that have increased litter size, duration of farrowing, and consequently the associated pain [ 1 ]. The way in which we house sows may act to amplify this pain.…”

The aim of this experiment was to determine whether administration of an anti-inflammatory compound to sows prior to farrowing would, via reduced pain and inflammation, increase piglet survival and growth. At day 114 of gestation, multiparous sows were randomly allocated to one of the following treatments: Control (n = 43), which received 10 mL saline, NSAID (n = 55) which received 0.4 mg/kg meloxicam and SAID (n = 54) which received 0.1 mg/kg dexamethasone. Treatments were applied again on day 116 if farrowing had not occurred. There was no treatment effect on piglets born alive or dead from parity two to four sows but in those of parity five and older, NSAID administration reduced the number of piglets born alive and increased the number of piglets born dead (p < 0.05). Sow rectal temperature and incidence of mastitis were unaffected by treatment (p > 0.05). Lactation day two plasma concentrations of cortisol, prostaglandin F2 alpha metabolite and haptoglobin did not differ among treatments (p > 0.05). Treatment effects were not observed in liveborn piglet mortality at any age, or litter weight at day 21 (p > 0.05). Average feed intake during lactation was increased by both NSAID and SAID treatments (p = 0.001). The use of meloxicam prior to farrowing should be avoided as it reduced the number of piglets born alive and did not improve piglet survival and growth.

“…Follicle development is inhibited during lactation, consequently, they reach a size of 0.3 cm to 0.6 cm [7]. Genetic issues cause a decrease in the reproductive capacity, which, in its turn, leads to a decrease in the number of young animals and their vitality [8,9].…”

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.
