Project description:Identification of the sex of modern, fossil and archaeological animal remains offers many insights into their demography, mortality profiles and domestication pathways. However, due to manifold factors, sex determination of such remains is often impossible. To overcome this, we have developed an innovative protocol to determine an animal sex applying label-free quantification (LFQ) of two unique AmelY peptides ‘LRYPYP’ (AmelY;[M+2]2+ 404.7212 m/z) and ‘LRYPYPSY’ (AmelY;[M+2]2+ 529.7689 m/z) that are solely present in tooth enamel of males. we applied this method to eight (8) modern cattle (Bos taurus) and (12) twelve archaeological samples of Bos from a Neolithic sites of Beisamoun, Israel (8th–7th millennium BC). Our methodology correctly identified the sex of the modern samples and enabled determination of sex in the archaeological samples.

Project description:High yielding dairy cattle undergo a state of NEB (negative energy balance) during the post-partum period when energy demand for lactation and maintenance exceeds energy intake. During this period in order to counteract NEB the liver under goes extensive metabolic and physiological change resulting in alteration in hepatic genes and miRNAs expression. We used Affymetrix Multispecies miRNA-2_0 Array with miRBase version 15 coverage to assess the liver miRNA expression in SNEB (severe NEB) and MNEB (mild NEB) Holstein Friesian cattle during the post-partum period.

A NEB model of Holstein Friesian was established such that 12 post-partum cattle were randomly assigned to MNEB and SNEB groups depending on different feeding and milking regimes

Project description:Puberty is a complex physiological event measured by various indicator traits in genetic improvement programs of beef cattle; thus, developing a more complete understanding of the genes and regulatory pathways and networks involved in puberty will provide knowledge to help improve genetic selection strategies. Herein, we characterized the transcriptome of five reproductive tissues (i.e. hypothalamus, pituitary gland, ovary, uterus, and endometrium) as well as tissues known to be relevant to growth and metabolism needed for cattle to achieve puberty (i.e., longissimus dorsi muscle, fat, and liver). These tissues were collected from pre (PRE)- and post (POST)-pubertal Brangus (3/8 Brahman; Bos indicus x 5/8 Angus; Bos taurus) heifers derived from a population of cattle used to identify QTL associated with fertility traits. In order to exploit the power of complementary omics analyses, PRE and POST puberty co-expression gene networks were constructed by combining the results from RNA-Seq, GWAS, and bovine transcription factors. RNA-Seq of 8 tissues among PRE and POST Brangus heifers revealed 1515 differentiallyexpressed and 943 tissue-specific genes within the 17,832 genes confirmed by metrics of RNA-Seq analysis. Combining the results from RNA-Seq and GWAS indentified a total of 25 QTL associated to heifer fertility. The hypothalamus experienced the most notable up-regulation of genes via puberty. Complementary omics procedures revealed 2,450 co-expressed genes across the 8 tissues relative to puberty. The PRE network had 372,861 connections whereas the POST network had 328,357 connections. A sub-network from this process revealed key transcriptional regulators (i.e., PITX2, FOXA1, TSG1D1, DACH2, LHX4, PROP1 and SIX6). Results from multiples sources of omics data will facilitate the design of breeding strategies to improve fertility in Bos indicus-influenced composite cattle. Sixty-one samples from PRE and POST pubertal composite beef heifers were analyzed with RNA-Seq. The transcriptome of five reproductive tissues (i.e. hypothalamus, pituitary gland, ovary, uterus, and endometrium) as well as tissues known to be relevant to metabolism andbody morphometrics needed for cattle to achieve puberty (i.e.,) was characterized. These tissues were collected from pre (PRE)- and post (POST)-pubertal Brangus (3/8 Brahman x 5/8 Angus) heifers derived from a population of cattle used to identify QTL associated with fertility. Total RNA was purified using a Trizol protocol (Invitrogen, Carlsbad, CA). Sequencing libraries were made using TruSeq RNA Sample Preparation kit of Illumina (San Diego, CA).

Project description:The aim of the study was to identify genes which are differentially expressed in the peripheral blood nuclear cells of two breeds of cattle (Holstein-Friesian and Polish Red) and cervine in different points in their physiological states (dry-off period, peak of lactation) RNA from peripheral blood nuclear cells taken from cattle and cervine in peak lactation and dry period were hybridized to Agilent two color microarrays with a common reference. There were four Holstein-Friesian cattle, four Polish Red cattle and four deer investigated. The whole blood was drawn in two time point from each animal – during dry period and peak lactation. This means that there were six research groups (Holstein-Friesian cattle in dry period and Holstein-Friesian cattle in peak lactation; Polish Red cattle in dry period and Polish Red cattle in peak lactation; Deer in dry period and Deer in peak lactation). Using Gene Spring Software (one-way ANOVA and Tukey's HSD Post-hoc test) three lists of differentially expressed transcripts were obtained: a list of 576 transcripts which differ deer in dry period and in peak lactation, a list of 437 transcripts which differ Holstein-Friesian cattle in dry period and in peak lactation and a list of 158 transcripts which differ Polish Red cattle in dry period and in peak lactation.

Project description:<p><strong>INTRODUCTION:</strong> Paratuberculosis, commonly known as Johne’s disease, is a chronic intestinal infection of ruminants caused by <em>Mycobacterium avium subspecies paratuberculosis</em> (MAP). Clinical signs, including reduced milk yields, weight loss and diarrhoea, are typically absent until 2 to 6 years post exposure.</p><p><strong>OBJECTIVES:</strong> To identify metabolomic changes profiles of MAP challenged Holstein-Friesian cattle and correlate identified metabolites to haematological and immunological parameters.</p><p><strong>METHODS:</strong> At approximately 6 weeks of age, calves (n = 9) were challenged with 3.8 x 10^9 cells of MAP (clinical isolate CIT003) on 2 consecutive days. Additional unchallenged calves (n = 9) formed the control group. The study used biobanked serum from cattle sampled periodically from 3- to 33-months post challenge. The assessment of sera using flow infusion electrospray high resolution mass spectrometry (FIE-HRMS) for high throughput, sensitive, non-targeted metabolite fingerprinting highlighted differences in metabolite levels between the two groups.</p><p><strong>RESULTS:</strong> In total, 25 metabolites which were differentially accumulated in MAP challenged cattle were identified, including 20 which could be correlated with certain haematological parameters, particularly monocyte levels.</p><p><strong>CONCLUSION: </strong>The targeted metabolites suggest shifts in amino acid metabolism that could reflect immune system activation linked to MAP and as well as differences in phosphocholine levels which could reflect activation of the Th1 (tending towards pro-inflammatory) immune response. If verified by future work, selected metabolites could be used as biomarkers to diagnose and manage MAP infected cattle.</p>
