(Submitter supplied) The objective of this work was to investigate differential gene expression of Charolais (n=90) and Holstein Freisian (n=77) steers divergent in RFI. The primary goal was to uncover genes and pathways associated with feed efficiency. Cattle were subjected to three different 70 day dietary phases. Initally animals were offered a high concentrate phase, termed "High Concentrate 1". Following this phase animals were offered sero grazed grass for 70 days followed by another high concentrate phase known as "High Concentrate 2". more...

(Submitter supplied) The objective of this study was to identify differentially expressed genes in the liver of steers with divergent Residual Feed Intake (RFI). Methods:In total 50 purebred Angus, 48 purebred Charolais and 158 Kinsella Composite breed steers were tested for individual feed intake using the GrowSafe system for an average period of 70 to 73 days. During the feedlot test animals were fed at ad libitum with a finishing diet composed of 75% barley grain, 20% barley silage and 5% rumensin pellet. more...

(Submitter supplied) Transcriptional profiling in skeletal muscle of 48 pigs (132 days of age) originated from two lines divergently selected for residual feed intake (RFI) : low-RFI pigs (RFIneg), high-RFI pigs (RFIpl). Both lines were offered isocaloric and isoproteic diets with contrasted energy source and nutrients: low fat, low fiber (LF) diet or a high fat, high fiber (HF)diet during 10 weeks. Effects of RFI selection, diet and interaction between diet and line were investigated.

(Submitter supplied) A transcriptomic approach was used to evaluate potential interactions between prepartum body condition score (BCS) and feeding management in the weeks before calving on hepatic metabolism during the transition period. Thirty-two mid-lactation grazing dairy cows of mixed age and breed were randomly allocated to one of four treatment groups in a 2 × 2 factorial arrangement: two prepartum BCS categories [4.0 (thin, BCS4) and 5.0 (optimal, BCS5); based on a 10-point scale], and two levels of energy intake during the 3 wk preceding calving (75 and 125% of estimated requirements). more...

(Submitter supplied) MicroRNAs (miRNAs) are short non-coding RNAs that post-transcriptionally regulate expression of mRNAs in many biological pathways. Here we report comprehensive miRNAs profiles by next-gen deep sequencing in Angus cattle divergently selected for residual feed intake (RFI) and identify miRNAs related to feed efficiency in beef cattle Results: Two microRNA libraries were constructed from pooled RNA extracted from livers of low and high RFI cattle, and sequenced by Illumina genome analyser. more...

(Submitter supplied) As polyphenols are exerting a broad spectrum of metabolic effects, we hypothesize that feeding of GSGME might influence other metabolic pathways in the liver which could account for the positive effects of GSGME observed in cows during early lactation. In order to investigate this hypothesis, we used using a genome-wide transcript profiling technique to explore changes in the hepatic transcriptome of cows supplemented with GSGME during the transition period. more...

(Submitter supplied) The selection of cattle with high feed efficiency is of paramount importance with regard to reducing feed costs in the beef industry. Global gene expression patterns in metabolically important tissues can be used to identify genes that are potentially involved in regulating feed efficiency. We identified 5 genes (p<0.001;FDR <0.1) to be differentially expressed in skeletal skeletal muscle between high and low residual feed intake heifers with all 5 transcripts being upregulated in the low residual feed intake phenotype. more...

(Submitter supplied) Background: The liver is central to most economically important metabolic processes in cattle. However, the changes in expression of genes that drive these processes remain incompletely characterised. RNA-seq is the new gold standard for whole transcriptome analysis but so far there are no reports of its application to analysis of differential gene expression in cattle liver. We used RNA-seq to study differences in expression profiles of hepatic genes and their associated pathways in individual cattle in either mild negative energy balance (MNEB) or severe negative energy balance (SNEB). more...

(Submitter supplied) Effect of breed in mid lactation Holstein (H) and Montbéliarde (M) cows on mammary glande miRNA profile. Genetic polymorphisms are known to influence milk production and composition. However, genomic mechanisms involved in the genetic regulation of milk component synthesis are not completely understood. MicroRNAs (miRNA) regulate gene expression. The objective of the present study was to compare mammary gland miRNomes of two dairy cow breeds, Holstein and Montbéliarde, with different dairy performances. more...

(Submitter supplied) The regulatory effects of H3K27me3 on target genes expressions were analyzed by comparing S. aureus mastitis resistant and susceptible cows. The differentially expressed genes are mainly associated with immune and disease-related processes, which were negatively regulated by H3K27me3 modification on the up 2Kb regions relative to TSS in S. aureus mastitis cattle.

To delineate the molecular response of C. more...
