(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) Residual feed intake (RFI) is a measure of feed efficiency, where low RFI denotes high feed efficiency. Caloric restriction (CR) is associated with feed efficiency in livestock species and to human health benefits such as longevity and cancer prevention. We have developed pig lines that differ in RFI and are interested to identify the genes and pathways that underlie feed efficiency. Prepubertal Yorkshire gilts with low RFI (n=10) or high RFI (n=10) were fed ad libitum or at 80% of maintenance for eight days. more...

(Submitter supplied) The objective of this study was to decipher the molecular basis of feed efficiency in meat-type chicken using duodenum tissues from a chicken population divergently selected for residual feed intake (RFI). Residual feed intake is the deviation of expected feed intake from actual feed intake. Chickens that consume less feed than expected are efficient (LRFI) and chickens that consume more feed than expected are inefficient (HRFI). more...

(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) Sustainable aquaculture, which entails proportional replacement of fish-based feed sources by plant-based ingredients, is impeded by the poor growth response frequently seen in fish fed high levels of plant ingredients. To evaluate the potential to improve, by means of early nutritional exposure, the growth of fish fed plant-based feed, rainbow trout swim-up fry were fed for 3 weeks either a plant-based diet (diet V, V-fish) or a diet containing fishmeal and fish oil as protein and fat source (diet M, M-fish). 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) We studied the influence of the oleic acid content of the diet on adipose tissue transcriptome. Iberian pigs were fed a standard (C) or a high oleic sunflower oil enriched (HO) diet. Transcriptome analyses were performed in adipose tissue samples (inner layer) obtained at slaughter (110 kg live weight) employing the Affymetrix porcine GeneChip. Normalized and filtered microarray expression data (background corrected and base-2 logarithmic-transformed) were analyzed through Bayesian inference using the GEAMM v.1.6 program. 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. Developing predictive biological markers specifically for improved feed efficiency is an attractive alternative to direct measurement on large numbers of animals.Evidence is provided that, effects of RFI on gene expression in muscle of beef cattle are not consistent across breed type or dietary phase. more...

(Submitter supplied) Backfat thickness is one of the most important traits of commercially raised pigs. Meishan pigs are renowned for having thicker backfat than Landrace pigs. To examine the genetic factors responsible for the differences, we first produced female crossbred pig lines by mating Landrace (L) × Large White (W) × Duroc (D) females (LWD) with Landrace (L) or Meishan (M) boars (i.e., LWD × L = LWDL for Landrace offspring and LWD × M = LWDM of the Meishan offspring). 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...
