Project description:Delivery of colostrum within the first several hours after birth is vital for establishing successful passive immunity in neonatal dairy calves. However, it is unclear whether the difference in colostrum feeding strategy can affect the development of the calf gastrointestinal tract. The aim of this study was to evaluate the effect of colostrum feeding time within the first 12 h after birth on the colonic mucosal immune system in neonatal calves using a genome wide transcriptome analysis.RNA sequencing based transcriptome analysis of colon tissues collected from twenty-seven male Holstein calves which were randomly assigned to one of three colostrum feeding strategies (immediately after birth (TRT0); 6 h after birth (TRT6); 12 h after birth (TRT12)) and were euthanized at 51 h of age detected 15935 ± 210, 15332 ± 415, and 15539 ± 440 expressed genes in groups, respectively. The core transcriptome of the colon in dairy calves included 12,678 genes, with enriched “cellular process” and “metabolic process” as the top three biological functions. Expression of 802 immune related genes were detected in the colon tissue. Principal component analysis of the transcriptomes did not display a clear separation by colostrum feeding strategy, and differential abundance analyses showed no significant difference in the expression of immune related genes among the treatments.Transcriptome analysis indicates that the development of the colonic mucosal immune system in neonatal calves may be independent of the timing of initial colostrum meal within 12 h after birth.

Project description:An early settlement of a complex gut microbiota can protect against gastro-intestinal dysbiosis, but the effects of neonatal microbiota colonization and early life feeding of medium chain triglycerides on the maturation of the porcine gastric mucosa are largely unknown. The transcriptome of the oxyntic mucosa of 24 caesarian-derived pigs previously associated with microbiota of different complexity and fed a diet fortified or not with medium chain fatty acids was studied. Pigs received pasteurized sow colostrum at birth (d0), 2 mL of starter microbiota (10^7 CFU of each Lactob. Amylovorus (LAM), Clostr. glycolicum, and Parabacteroides spp.) on d1-d3 of age and either a placebo inoculant (simple association, SA) or an inoculant consisting of diluted feces of an adult sow (complex association, CA) on d3-d4 of age. Then half of pigs was fed a moist diet (CON) or, for the remaining half, CTRL fortified in medium chain triglycerides with 7% coconut oil ( MCT). Gastric samples were obtained at on euthanised pigs at 3 weeks of age.

Project description:Here we studied the glycation of bovine milk proteins by lactose as dominant sugar in milk and hexoses using tandem mass spectrometry (CID and ETD mode). In a bottom-up proteomics approach after enriching glycated peptides by boronate affinity chromatography, first we could identify 260 lactosylated peptides corresponding to 124 lactosylation sites in 28 bovine milk proteins in raw milk, raw colostrum, three brands of pasteurized milk, three brands of UHT milk, and five brands of infant formula. The same regular and additionally two lactose-free milk products (pasteurized and UHT milk) where lactose is enzymatically cleaved into the more reactive hexoses were analyzed in terms of hexosylation sites that resulted in identification of 124 hexosylated tryptic peptides corresponding to 86 glycation sites in 17 bovine milk proteins. In quantitative terms glycation increased from raw milk to pasteurized milk to UHT milk and infant formula, i.e., with the harsher processing conditions. Lactose-free milk contained significantly higher hexosylation degrees than the corresponding regular milk product.

Project description:Breast milk is the primary source of nutrition for newborns, and rich in immunological components. microRNAs (miRNAs), a well-defined group of non-coding small RNAs, are present in various body fluids (such as breast milk), which are selectively packaged inside the exosomes, a type of membrane vesicles, secreted by most cell types. These exosomal miRNAs could be actively delivered into recipient cells, and regulate target gene expression and recipient cell function. We present the lactation-related miRNA expression profiles in porcine milk exosomes across entire lactation period in pig industry (newborn to 28 days after birth) using deep sequencing technology. We found that the immune-related miRNAs are presented and enriched in breast milk exosomes, and generally resistant to relatively harsh conditions. Notably, these exosomal miRNAs exhibited the higher abundances in the colostrum (newborn to 3 days after birth) than that in the mature milk (7 to 28 days after birth), as well as in the serum of colostrum-feeding piglets compared with the only mature milk-feeding piglets. These immune-related miRNAs-loaded exosomes in breast milk may be transferred into the infant body via the digestive tract. These observations are prelude to the in-depth investigations of the essential roles of the breast milk in the development of the infant’s immune system.

Project description:An early settlement of a complex gut microbiota can protect against gastro-intestinal dysbiosis, but the effects of neonatal microbiota colonization on the gut barrier upon the further encounter of favorable bacteria or not, are largely unknown. The jejunal transcriptome of differently perfused intestinal loops of 12 caesarian-derived pigs previously associated with microbiota of different complexity was studied. Pigs received pasteurized sow colostrum at birth (d0), 2 mL of starter microbiota (10^7 CFU of each Lactob. Amylovorus (LAM), Clostr. glycolicum, and Parabacteroides spp.) on d1-d3 of age and either a placebo inoculant (simple association, SA) or an inoculant consisting of diluted feces of an adult sow (complex association, CA) on d3-d4 of age. On days 26-37 of age, jejunal loops were perfused for 8 h with either enterotoxigenic E. coli F4 (ETEC), F4 fimbriae (F4), LAM or saline (CTRL) and jejunal samples were obtained from each piglet immediately afterwards.

The analysis of whole mRNA transcript expression was done by Affymetrix©Porcine Gene 1.1 ST array strips, a Robust Multichip Analysis was performed on the CEL files, and Transcripts IDâs were associated to 13,406 Human gene names, based on Sus scrofa Ensemble
