Selection for increased litter sizes have decreased the average birth weight of piglets and up to 30% of newborn piglets in Danish herds show signs of intrauterine growth restriction (IUGR). It has been reported that around 48% of liveborn piglets dying between birth and weaning have empty stomachs, and that IUGR piglets do not ingest the recommended amount of colostrum to survive. The aim of this study was to investigate how much colostrum could be administrated depending on whether they were IUGR compared to normal piglets. Seventy-two piglets within 24 h of farrowing were classified as either IUGR or normal based on their head morphology. Stomach weight, length and capacity were measured along with bodyweight (BW). The results displayed a decreased BW, empty stomach weight and capacity in IUGR piglets, as well as a decreased relative stomach capacity in IUGR compared with normal piglets. In conclusion, birth weight is not the only factor influencing stomach capacity, and IUGR piglets have a smaller stomach capacity compared with normal piglets. It is estimated that IUGR piglets have the capacity to be given a bolus of 25 mL per kg/BW, whereas a normal piglet have a higher capacity (30 mL per kg/BW).

Differentially Methylated Genes

Intrauterine growth restriction (IUGR) remains a major problem in swine production since the associated low birth weight leads to high rates of pre-weaning morbidity and mortality, and permanent retardation of growth and development. The underlying regulatory mechanisms from the aspects of epigenetic modification has received widespread attention. Studies explore the changes in genome wide methylation in small intestine (SI), liver and longissimus dorsi muscle (LDM) between IUGR and normal birth weight (NBW) newborn piglets using a methylated DNA immunoprecipitation-sequencing (MeDIP-Seq) approach. The data demonstrated that methylated peaks were prominently distributed in distal intergenic regions and the quantities of peaks in IUGR piglets were more than that of NBW piglets. IUGR piglets had relatively high methylated level in promoters, introns and coding exons in all the three tissues. Through KEGG pathway analysis of differentially methylated genes found that 33, 54 and 5 differentially methylated genes in small intestine, liver and longissimus dorsi muscle between NBW and IUGR piglets, respectively, which are related to development and differentiation, carbohydrate and energy metabolism, lipid metabolism, protein turnover, immune response, detoxification, oxidative stress and apoptosis pathway. The objective of this review is to assess the impact of differentially methylation status on developmental delay, metabolic disorders and immune deficiency of IUGR piglets.

OBJECTIVE: To investigate the relationship between physical activity during the second trimester pregnancy and low birth weight, preterm birth, and intrauterine growth restriction. METHODS: Case-control study including 273 low birth weight newborns and 546 controls carried out in the city of São Paulo, Southeastern Brazil, in 2005. Low birth weight cases were grouped into two subsamples: preterm birth (n=117) and intrauterine growth restriction (n=134), with their related controls. Information was collected by means of interviews with mothers shortly after birth and transcription of medical records. Data were analyzed using conditional multiple and hierarchical logistic regression. RESULTS: Light physical activity for over 7 hours per day was shown to be protective against low birth weight (adjusted OR=0.61; 95% CI 0.39-0.94) with a dose-response relationship (p-value for trend=0.026). A similar trend was found for intrauterine growth restriction (adjusted OR=0.51; 95% CI 0.26-0.97). Homemaking activities were associated as a protective factor for both low birth weight and preterm birth (p-value for trend=0.013 and 0.035, respectively). Leisure-time walking was found to be protective against preterm birth. CONCLUSIONS: Mild physical activity during the second trimester of pregnancy such as walking has an independent protective effect on low birth weight, preterm birth, and intrauterine growth restriction.

Risk factors associated with intrauterine growth restriction (IUGR) have previously been identified, but few studies have described the relationship between IUGR and maternal stress caused by exposure to civil unrest. Here, we investigate this relationship during the Mount Elgon crisis in western Kenya between 2006 and 2008, following a period of violence. Birth weight data were compared between three hospitals in an exposed area, Mount Elgon (n=570), and one hospital in a control area, Kimilili (n=530). In a sub-analysis, the most stress exposed hospital, Bungoma West (n=211), was compared with the control hospital in Kimilili. Adjustments were made for offspring sex, gestational age and parity. The difference in mean birth weight between the most stress-exposed hospital (Bungoma West) and the control hospital (Kimilili) was 91 g after full adjustment (P=0.041). In conclusion, epidemiological data suggest a significant relationship between exposure to civil unrest and IUGR causing lower birth weight.

Background: Poor fetal nutrient availability predisposes to adult cardiovascular disease (CVD). We have developed a fetal baboon model of maternal undernutrition resulting in Intrauterine Growth Restriction (IUGR) in both male and female fetuses (Li, et al, J Endocrinol, 2013). MicroRNAs are small non-coding RNAs that regulate gene expression through mRNA degradation and translational repression. Hypothesis: We hypothesized that IUGR is accompanied by cardiac dysfunction and dysregulation of cardiac miRNAs. Methods: Six control pregnant baboons ate ad libitum, and six nutrient restricted pregnant baboons ate a globally reduced diet (70% of control feed) from 0.16 gestation (G) through pregnancy resulting in fetal IUGR compared to controls (p<0.05). No differences in heart weight were observed. Fetuses (3 males and 3 females per group) were euthanized at C-section at 0.9G. Cardiac sections were studied for morphological changes and fibrosis using H&E and Masson’s trichrome staining respectively. Total left ventricular RNA was isolated and miRNA array was performed. Results: While no differences in myofiber orientation were observed, IUGR male but not female fetuses showed a reverse correlation between birth weight and accumulation of fibrotic tissue in the heart (r=-0.831, p=0.01). We next investigated the expression of the extracellular matrix proteins thrombospondin-1 (TSP-1) and connective tissue growth factor (CTGF). A reverse correlation between birth weight and cardiac TSP-1 levels (r=-0.77, p=0.03) was found in male but not female fetuses. No changes in CTGF were observed. Sexual dimorphism was observed in fetal cardiac miRNA expression within both IUGR and control groups. In male IUGR group, the increase in levels of TSP-1 was associated with more than 50% reduction in expression of its targeting miRNA-19a, reduction in which has been implicated in CVD. Other CVD-related and differentially expressed miRNAs in male IUGR included miRNA-23b, 27b, 99b, 143, 181a, and 378-3p. Summary: IUGR resulting from decreased maternal nutrition is associated with sexual dimorphism in cardiac structure and miRNA expression. If the changes observed in male IUGR fetuses persists postnatally they may program offspring for higher CVD risk later in life.

Neonatal Problems

Intrauterine growth restriction (IUGR), a condition that occurs due to various reasons, is an important cause of fetal and neonatal morbidity and mortality. It has been defined as a rate of fetal growth that is less than normal in light of the growth potential of that specific infant. Usually, IUGR and small for gestational age (SGA) are used interchangeably in literature, even though there exist minute differences between them. SGA has been defined as having birth weight less than two standard deviations below the mean or less than the 10th percentile of a population-specific birth weight for specific gestational age. These infants have many acute neonatal problems that include perinatal asphyxia, hypothermia, hypoglycemia, and polycythemia. The likely long-term complications that are prone to develop when IUGR infants grow up includes growth retardation, major and subtle neurodevelopmental handicaps, and developmental origin of health and disease. In this review, we have covered various antenatal and postnatal aspects of IUGR.
