“…The lower IGF1 levels in the restricted sows may have played an important role in the regulation of reduced follicular growth, steroid production and oocyte developmental competence (Němcová et al, 2007; Xia et al, 1994; Zhou et al, 2013). Our findings are corroborated by recent findings of Han (2021a), where sows that received feed restriction during the last 2 weeks of a 28‐day lactation had 4 days after weaning lower follicular fluid IGF1 levels as compared to full‐fed sows. Interestingly, Han et al also describe that higher IGF1 levels in serum at weaning were related to a higher mean piglet birth weight in the next litter, indicative of long term consequences (Han et al, 2021b).…”

Metabolic demands of modern hybrid sows have increased over the years, which increases the chance that sows enter a substantial negative energy balance (NEB) during lactation. This NEB can negatively impact reproductive outcome, which is especially evident in primiparous sows causing a reduced second parity reproductive performance. The negative effects of the lactational NEB on reproductive performance can be partly explained by the influence of the premating metabolic state, during and after lactation, on the development of follicles from which oocytes will give rise to the next litter. In addition, the degree and type of body tissue mobilization during lactation that is, adipose tissue or lean mass, highly influences follicular development. Research investigating relations between the premating metabolic state and follicular and oocyte competence in modern hybrid sows, which experience higher metabolic demands during lactation, is limited. In this review we summarize current knowledge of physiological relations between the metabolic state of modern hybrid sows and follicular developmental competence. In addition, we discuss potential implications of these relations for current sow management strategies.

“…MET failed to increase voluntary feed intake (Mathews et al, 2021). This steady feed intake and increased milk production could lead to a more severe negative energy balance at the end of lactation, which might negatively affect subsequent litter characteristics (Han, 2021). Nevertheless, it is promising that Farmer and Palin (2021) established an increased IGF‐1 concentration in DOM‐treated sows, which is one of the most important hormones for subsequent reproduction, and litter birth weight and uniformity (Han et al, 2021).…”

Reproductive health of the sow during puerperium

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.
