Blood immune transcriptome analysis of artificially fed dairy calves and naturally suckled beef calves from birth to 7 days of age

Project description:The aim of the overall study was to investigate the development of immune competence in artificially reared dairy calves and in two breeds of naturally suckled beef calves over the first 168h of life. Dairy calves were fed 5% total body weight of colostrum, with beef calves monitored to ensure natural ingestion of colostrum. Blood samples were taken from all calves at 24h 48h 72h and 168h, and analysed for alterations to immunes genes.

Transcriptomic analysis of adipose and muscle of dairy calves supplemented with 5-hydroxytryptophan

Project description:Serotonin is a monoamine that regulates processes such as energy balance and immune function. Manipulating this pathway in growing dairy calves could promote growth and development by modulating functions and signaling pathways within key organs. In this study, we characterized the adipose and muscle transcriptome of pre-weaned calves with increased serotonin bioavailability through the elucidation of differentially expressed genes.

Assessment of the effect of nutrition level on transcriptome of mammary gland structural components (parenchyma (PAR) and fat pad (MFP)) and liver in dairy calves mammary gland in dairy calves

Project description:The aim of this study was to identify changes in transcriptome of parenchyma (PAR), fat pad (MFP) and liver in dairy calves. Our earlier results showed that feeding management regulates the dynamics of organ growth in preweaned heifers. We observed that a daily dose of 5.3 kg of milk replacer inhibits mammary gland development. Therefore, this research aims at evaluation of the influence of the nutritional level in the early life period of calves on the biological processes related to the development of the mammary gland through transcriptomic alterations.

Experimental challenge with bovine herpesvirus 1 in dairy calves: bronchial lymph node mRNA transcriptome response

Project description:Bovine Herpesvirus 1 (BoHV1) is a leading cause of Bovine Respiratory Disease (BRD) in young calves, which is responsible for substantial morbidity and mortality. Therefore, the objective of the current study was to elucidate the bronchial lymph node mRNA transcriptomic response to an experimental challenge with BoHV1, in dairy calves. Holstein-Friesian calves were either challenged by intranasal atomisation with BoHV1 virus (6.3 x 10^7/mL x 1.35mL) (n=12) or mock challenged with sterile phosphate buffered saline (n=6). Clinical signs were scored daily until euthanasia at day 6 post-challenge. Total RNA was extracted and sequenced from bronchial lymph node tissue (150 bp paired-end). Sequence reads were aligned to the ARS-UCD1.2 bovine reference genome and differential gene expression analysis was performed using EdgeR. An MDS plot displayed an obvious separation between BoHV1 challenged and control calves based on bronchial lymph node gene expression changes. There were 337 differentially expressed (DE) genes (p < 0.05, FDR < 0.1, fold change > 2) between the BoHV1challenged and control calves.

Experimental challenge with bovine herpesvirus 1 in dairy calves: cranial lung lobe mRNA transcriptome response

Project description:Bovine Herpesvirus 1 (BoHV1) is a leading cause of Bovine Respiratory Disease (BRD) in young calves, which is responsible for substantial morbidity and mortality. Therefore, the objective of the current study was to elucidate the cranial lung lobe mRNA transcriptomic response to an experimental challenge with BoHV1, in dairy calves. Holstein-Friesian calves were either challenged by intranasal atomisation with BoHV1 virus (6.3 x 10^7/mL x 1.35mL) (n=12) or mock challenged with sterile phosphate buffered saline (n=6). Clinical signs were scored daily until euthanasia at day 6 post-challenge. Total RNA was extracted and sequenced from cranial lung lobe tissue (lesioned and healthy) (150 bp paired-end). Sequence reads were aligned to the ARS-UCD1.2 bovine reference genome and differential gene expression analysis was performed using EdgeR. There were 334 differentially expressed genes in the healthy cranial lobe tissue, between BoHV1 challenged and control calves, and there were 67 differentially expressed genes

In vitro investigations on the impact of constituents on fermented dairy on fecal microbiota composition

Project description:The consumption of fermented food has been linked to positive health outcomes due to a variety of functional properties. Fermented dairy constitutes a major dietary source and contains lactoseas main carbohydrate and living starter cultures. To investigate whether nutritional and microbial modulation impacted intestinal microbiota composition and activity, we employed fecal microbiota fermentations and a dairy model system consisting of lactose and β-galactosidase positive and negative Streptococcus thermophilus. Based on 16S rRNA gene based microbial community analysis, we observed that lactose addition increased the abundance of Bifidobacteriaceae, and of Veillonellaceae and Enterobacteraceae in selected samples. The supplied lactose was hydrolysed within 24 h of fermentation and led to higher expression of community indigenous β-galactosidases. Targeted protein analysis confirmed that bifidobacteria contributed most β-galactosidases together with other taxa including Escherichia coli and Anaerobutyricum hallii. Lactose addition led to 1.1-1.8 fold higher levels of butyrate compared to controls likely due to (i) lactate-crossfeeding and (ii) direct lactose metabolism by butyrate producing Anaerobutyricum and Faecalibacterium spp. Representatives of both genera used lactose to produce butyrate in single cultures. When supplemented at around 5.5 log cells mL-1, S. thermophilus or its beta-galactosidase negative mutant outnumbered the indigenous Streptococcaceae population at the beginning of fermentation but had no impact on lactose utilisation and final SCFA profiles. This study brings forward new fundamental insight into interactions of major constituents of fermented dairy with the intestinal microbiota. We provide evidence that lactose addition increases fecal microbiota production of butyrate through cross-feeding and direct metabolism without contribution of starter cultures.
