Project description:probiotics and prebiotics to maternal diets is related to decreased incidence of diarrhea and greater weight gain during lactation. Our objective was to determine the impact of adding whole ground oat as a prebiotic alone or in combination with postbiotic yeast culture (YC) (Saccharomyces cerevisiae) to sow gestation and lactation rations on milk composition, piglet growth, and incidence of post weaning diarrhea (PWD). Diets: control (CON), CON + yeast culture (YC) [5g/kg], CON + oat (15% inclusion rate) (Oat) or CON+ YC [5g/kg] + Oat (15%) were fed during the last 30 days of gestation and throughout lactation (18-21 days). Shotgun proteome analysis of day 4 and 7 postpartum milk samples found 36 differentially abundant proteins (P-adj <0.1) in both Oat and YC supplemented sows relative to CON. Notable was increased expression of antimicrobial proteins, lactoferrin and chitinase. IgG in milk of Oat supplemented sows was lower than YC supplemented sows (p<0.05) but had greater E. coli-antigen reactivity. Piglet weights at birth were similar. At weaning YC + Oat piglets weighed less and gained less weight (p<0.05) postweaning than CON. The incidence of PWD was lowest in the YC and Oat groups compared to CON and YC+ Oat groups. These data suggest that Oat or YC culture supplementation alters milk immune and antimicrobial associated proteins that can impact piglets but may have negative effects on piglet growth when given in combination.

Project description:Large litters of modern sows have complicated the rearing of piglets during the suckling period. The subpopulation of piglets with low birth weight and reduced growth potential has increased and has contributed to increasing the mortality rate from birth to weaning. Two of the most important measures to reduce mortality rate is to ensure sufficient energy and nutrient intake, while creating a safe rearing environment for vulnerable piglets. Use of complete artificial rearing with physical absence of the sow, with inclusion of unlimited access to a milk replacer high in fat and protein might potentially improve growth of low-birth-weight piglets.

Project description:Transcriptional profiling of Day 30 embryos (D30E) was performed. First parity sows were submitted to an ovulation-induction protocol, intermittent suckling (IS), during lactation. IS consisted of 8 h/d separation from their litters during the last 7d of a 28d lactation. During separation, sows received boar exposure. There were 3 treatments: control (C28, n=19), where piglets were weaned at D28 of lactation and were bred after weaning and two IS treatments: sows were either bred at their first induced estrus during lactation (IS21FE, n=18), or were “skipped” and bred at their second estrus (IS21SE, n= 17) which occurred after final weaning at D28. Sows were slaughtered and embryos were collected on D30 of gestation for DNA PCR sexing. Later, D30E from the same sex with similar weight were pooled for further microarray investigation.

Project description:Maternal stress occuring during gestation can influence the functioning of the stress and immune responses in offspring. Maternal supplementation with immunomodulatory compounds such as omega-3 polyunsaturated fatty acids may reduce inflammation associated with maternal stress, promoting offspring health and growth Sows were fed diets supplemented with microalgae or fish oil from gestation day 75 and were challenged with LPS on gestation day 112. Previously, LPS challenge in the male piglets of these sows resulted in differences in fever and cortisol responses among piglets from different maternal treatments. Therefore, the adrenal gland was chosen for microarray analysis to assess the effects of the maternal treatment on the gene expression within the hypothalamic-pituitary-adrenal axis.

Stimulating lactational oestrus then two mating strategies were applied to primiparous sows. For the microarray experiment, three biological replicates (three sows) were chosen from each treatment group comparing control (C28) to either IS21FE or IS21SE. A pool of females and males D30E were chosen and pooled separately for each comparison.

Project description:The transcriptome changes of the ileal mucosa in suckling piglets during early postnatal life were analysed to contribute to the knowledge of a pig’s gut development. In addition, the ileal transcriptome of suckling piglets was compared with that of age-matched weaned piglets (weaned at the age of 21 days) to elucidate the effect of weaning on the developing gut. DNA microarray was used to analyse the change of transcriptome profiles and biological pathways in porcine ileum that occurred during the developmental or the weaning process.

Project description:The majority of babies in the US are formula-fed instead of breast fed. There are major differences in the composition of formulas and breast milk and yet little is known about metabolic differences in babies as the result of feeding these very different diets and how that might affect development or disease risk in later life. One concern is that soy-based formulas might have adverse health effects in babies as a result of the presence of low levels of estrogenic phytochemicals genistein and daidzein which are normally present in soy beans. In the current study, we used a piglet model to look at this question. Piglets were either fed breast milk from the sow or were fed two different infant formulas (cow's milk-based or soy-based) from age 2 days to 21 days when pigs are normally weaned onto solid food. Blood glucose and lipids were measured. Formula-fed pigs were found to have lower cholesterol than breast fed piglets and in addition had larger stores of iron in their liver.Microarray analysis was carried out to see if changes in liver gene expression could explain these effects of formula feeding. It was found that overall gene expression profiles were influenced by formula feeding compared to breast fed neonates. Gender-independent and unique effects of formula influenced cholesterol and iron metabolism. Further, soy formula feeding in comparison to milk-based formula failed to reveal any estrogenic actions on hepatic gene expression in either male or female pigs. Piglets (female, male) were either fed breast milk from the sow or were fed two different infant formulas (cow's milk-based or soy-based) from age 2 days to 21 days when pigs are normally weaned onto solid food.

Project description:Background: This study investigated the effects of dietary soy isoflavone supplementation on reproductive performance, antioxidant capacity, and colostrum-derived exosomal microRNA profiles in sows, with the aim of exploring the molecular basis of maternal–offspring integrated regulation. A total of 120 Landrace × Yorkshire sows were assigned to either a control diet or a diet supplemented with 200 mg/kg soy isoflavone from gestation day 106 to lactation day 28. Reproductive performance and serum antioxidant indices were evaluated, and colostrum-derived exosomes were isolated for small RNA sequencing and bioinformatic analysis. Results: Dietary soy isoflavone supplementation significantly increased the total number of piglets born, the number of live-born piglets, litter weight at birth, and litter weight at weaning, while shortening farrowing duration (P < 0.05). In addition, soy isoflavone significantly elevated serum total antioxidant capacity and catalase activity on lactation day 21 (P < 0.05). Transmission electron microscopy, nanoparticle tracking analysis, and flow cytometry confirmed the successful isolation of colostrum-derived exosomes. Small RNA sequencing showed that most microRNAs ranged from 18 to 26 nucleotides, with a predominant peak at 22–23 nucleotides. Principal component analysis and differential expression analysis revealed that soy isoflavone markedly reshaped the microRNA cargo of colostrum-derived exosomes. Functional enrichment analysis indicated that the predicted target genes of differentially expressed microRNAs were mainly involved in transcriptional regulation, kinase-mediated signaling, inflammatory responses, and metabolic pathways, including mitogen-activated protein kinase, Ras, Rap1, endocytosis, autophagy, and adherens junction pathways. Integrated network analyses further suggested coordinated regulation of inflammatory signaling and metabolic homeostasis. Conclusions: Dietary soy isoflavone supplementation improved sow reproductive performance and antioxidant capacity, while reshaping colostrum-derived exosomal microRNA profiles and their associated regulatory networks. These findings provide a potential molecular basis for maternal–offspring integrated regulation.

Project description:Transcriptional profiling of 25d old piglets comparing control untreated suckling jejunum with weaned piglets' jejunum. The goal was to gain new insight into the interaction between weaning and intestinal function.A keen interest is paid in deciphering expression changes of apoptosis or cell cycle control genes. The statistical analysis of gene ontology revealed that most of these altered genes are metabolic-related enzymes and regulators which may involved in the biological regulation, developmental process, and cellular process. Weaning also causes alterations in various immune response pathways. Results likely indicate that weaning induced cell cycle arrest, enhanced apoptosis, and inhibited cell proliferation. Two-condition experiment, suckling control piglets' jejunum vs. weaned piglets' jejunum. Biological replicates: 4 control replicates, 4 weaned replicates.
