Project description:The objectives of the study were to use RNA-Seq to examine the effect of (i) breed and (ii) gradual weaning, on the whole blood mRNA transcriptome of artificially reared Holstein-Friesian and Jersey calves. The calves were gradually weaned over 14 days (day (d) -13 to d 0) and mRNA transcription was examined one day before gradual weaning was initiated (d -14), one day after weaning (d 1) and 8 days after weaning (d 8). RNA-seq analysis was carried out on RNA extracted from whole blood. Gradual weaning had no effect on gene expression (P>0.05).There were 550 differentially expressed genes at a false discovery rate of 10% and with a â¥1.5-fold change, between Holstein-Friesian and Jersey calves on d -14, 490 on d 1, and 411 on d 8. GOseq/KEGG pathway analysis showed that the cytokine-cytokine receptor interaction pathway and the neuroactive ligand-receptor interaction pathway were over-represented between breeds on all days (P<0.01; Qâ¤0.1). These results demonstrate that the gradual weaning practiced here does not compromise the welfare of artificially-reared dairy calves, evidenced by the lack of expression changes in any genes in response to gradual weaning. These data also suggest differences in cell signalling and immune responses between breeds. Eight Holstein-Friesian and eight Jersey bull calves were group housed indoors and individually fed milk replacer and concentrate using an automatic feeder. Calves were gradually weaned by reducing milk-replacer from 6 litres to 0 litres over 14 days (d) (d -13 to d 0). Calves were blood sampled on d -14, 1, and 8, relative to weaning (d 0). RNA-seq analysis was carried out on RNA extracted from whole blood.

Project description:Bovine Herpesvirus 1 (BoHV-1) 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 whole blood mRNA transcriptomic response to an experimental challenge with BoHV-1, 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 whole blood (100 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 BoHV-1 challenged and control calves based on the gene expression changes in whole blood. There were 488 differentially expressed (DE) genes (p < 0.05, FDR < 0.1, fold change > 2) between the BoHV-1 challenged and control calves.

Project description:Bovine Respiratory Syncytial Virus (BRSV) is a leading cause of Bovine Respiratory Disease (BRD) in young calves, which is responsible for substantial morbidity and mortality. Infection with BRSV induces global gene expression changes in respiratory tissues. If these changes are observed in tissues which are accessible in live animals, such as whole blood, they may be used as biomarkers of the disease. Therefore, the objective of the current study was to elucidate the whole blood transcriptomic response to an experimental challenge with BRSV, in dairy calves. Holstein-Friesian calves were either inoculated with virus (103.5 TCID50/ml x 15 ml) (n=12) or mock challenged with sterile phosphate buffered saline (n=6). Clinical signs were scored daily and whole blood was collected in Tempus RNA tubes immediately prior to euthanasia, at day 7 post-challenge. RNA was extracted from blood and sequenced (150 bp paired-end). Sequence reads were aligned to the UMD3.1 bovine reference genome and differential gene expression analysis was performed using EdgeR. An MDS plot displayed an obvious separation between BRSV challenged and control calves based on whole blood gene expression changes, despite an observed mild clinical manifestation of the disease. There were 281 differentially expressed (DE) genes (p < 0.05, FDR < 0.1, fold change > 2) between the BRSV challenged and control calves. The top enriched KEGG pathways and gene ontology terms were associated with viral infection and included “Influenza A”, “defense response to virus”, “regulation of viral life cycle” and “innate immune response”. Highly DE genes involved in these pathways are may be beneficial for the diagnosis of subclinical BRD from blood samples.

Project description:<p><strong>BACKGROUND:</strong> Long-distance transportation, a frequent practice in the cattle industry, stresses calves and results in morbidity, mortality and growth suppression, leading to welfare concerns and economic losses. Alkaline mineral water (AMW) is an electrolyte additive containing multiple mineral elements and shows stress-mitigating effects on humans and bovines.</p><p><strong>RESULTS:</strong> Here, we monitored the respiratory health status and growth performance of 60 Simmental calves subjected to 30 hours of road transportation using a clinical scoring system. Within the three days of commingling before the transportation and 30 days after the transportation, calves in the AMW group (n = 30) were supplied with AMW, while calves in the Control group (n = 29) were not. On three specific days, namely the day before transportation (day -3), the 30th day (day 30) and the 60th day (day 60) after transportation, sets of venous blood, serum and nasopharyngeal swab samples were collected from ten calves for routine blood testing, serology detection, whole blood transcriptomic sequencing, serum untargeted metabolic sequencing and 16S rDNA sequencing. The field data showed that calves in the AMW group displayed lower rectal temperatures (38.967 vs 39.022 °C; p < 0.001), respiratory scores (0.079 vs 0.144; p < 0.001), appetite scores (0.024 vs 0.055; p < 0.001), ocular and ear scores (0.185 vs 0.338; p < 0.001), nasal discharge scores (0.143 vs 0.241; p < 0.001) and higher body weight gains (30.87 vs 7.552 kg; p < 0.001). The outcomes of laboratory and high throughput sequencing data revealed that the calves in the AMW group demonstrated higher cellular and humoral immunities, antioxidant capacities, intestinal absorption and lipogenesis abilities, and lower inflammatory levels on days -3 and 60. The nasopharynx 16S rDNA microbiome results revealed the different composition and structure of the nasopharyngeal microflora in the two groups of calves on day 30. Joint analysis of multi-omics revealed that on days -3 and 30, bile secretion was a shared pathway enriched by differentially expressed genes and metabolites, and there were strong correlations between the differentially expressed metabolites and the main genera in the nasopharynx.</p><p><strong>CONCLUSIONS:</strong> These results suggest that AMW supplementation enhances peripheral immunity, nutrition absorption and metabolic processes, subsequently affecting the nasopharyngeal microbiota and improving the respiratory health and growth performance of transported calves. This investigation provided a practical approach to mitigate transportation stress and explored its underlying mechanisms, which are beneficial for the development of the livestock industry.</p>

Project description:Objectives: Identify gene products that characterize the biological status of typical calves which have been recently weaned, transported, and co-mingled prior to arrival at stocker facilities in order to identify gene products associated with BRD resistance. Methods: Whole blood RNA profiles were generated via NGS approach, using an Illumina HiSeq 3000. Individual samples were processed using an adaptation of the Revised Tuxedo Suite protocol (Tuxedo 2), then analyzed in R using edgeR and DESeq2 with likelihood-ratio testing. Genes were considered differentially expressed with an FDR cutoff of 0.10. qRT-PCR validation was performed using a SYBR green assay. Results: 135 differentially expressed genes were identified between healthy and BRD animals; 36 were shared between edgeR and DESeq2. Biological processes, using the 36 DEGs, were identified to be involved with inflammation, defense response, macrophage function, and lipoxin metabolism/biosynthesis. Enriched pathways of the 36 DEGs were involving SPM synthesis and angiotensinogen metabolism to angiotensins. Genes increased in diseased animals had known function towards anitmicrobial activity. Conlusions: Our analysis has provided, for the first time, a list of whole blood molecular biomarkers that may predict disease risk in the first 28 days of stocker cattle arrival. We identified pathways related to immune response, inflammatory mediation, metabolic processes, and stress regulation. Using whole blood transcriptomic analysis, this study provides an insight to host immunity in response to BRD.

Project description:This objective of this study was to identify gene expression and biological mechanisms related to trace mineral metabolism, central to inflammatory mediation and disease development, through the evaluation of the whole blood transcriptome in post‐weaned cattle receiving different mineral treatments. Here, 56 high‐risk cross-bred beef cattle (~250 kg) were assigned to receive ad libitum access to supplements containing 1 of 3 treatments over a 60-day period: 1) sulfate sources of Cu, Co, Mn, and Zn in feed (INR; custom blend; n= 40); 2) organic complexed source of Cu, Mn, Co, and Zn in feed (AAC; Availa4; n = 40); or 3) organic complexed source of Cu, Mn, Co, and Zn in feed and administration of a drench product [ProFusion] upon arrival (COMBO; n = 40). Whole blood RNA from 26 cattle (~4 calves/pen) were matched and utilized to assess the host transcriptome at days 0, 13, 28, 45, and 60 for the assessment of host transcriptome responses over time.
