(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) 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) Chickens divergently selected for either high growth (HG genotype) or low growth (LG genotype) at SRA-INRA, France were used to profile abdominal adipose gene expression at 7 wk of age. The HG and LG chickens are different in various phenotypic and metabolic measurements, including growth rate, abdominal fat, plasma glycemia, insulinemia, T4, T3, triglyceride and NEFA. The HG and LG chickens are valuable as a model for biomedical and agricultural traits. more...

(Submitter supplied) Several processes governing growth and metabolism are regulated by the neuroendocrine system, particularly the trophic hormones produced in the anterior pituitary gland. However, many of the differences that exist in pituitary gene expression and functional gene networks associated with divergent growth characteristics are still largely unknown. Using the Del-Mar 14K Chicken Integrated Systems microarray, this experiment evaluated global gene expression in the anterior pituitary gland during the first 7 weeks of post-hatch growth in two lines of chickens genetically selected for high growth (HG) or low growth (LG) at SRA-INRA, France. more...

(Submitter supplied) The processing ability of chicken meat is highly related to its ultimate pH (pHu), which is mainly determined by the amount of glycogen in the muscle at death. The molecular mechanisms involved in variations of those traits for chicken remain to be fully described. For that purpose, two chicken lines were divergently selected on breast meat pHu, i.e. the pHu- and the pHu+ lines. In this study, Chicken Genome Arrays (60 K) were used to compare muscle gene expression profiles of chickens from both lines. more...
