Effect of selection on residual feed intake on gene expression in porcine liver (115 kg body weight)

Transcriptional profiling in liver of 24 pigs of 115 kg body weight from lines divergently selected for residual feed intake (RFI): low-RFI pigs fed ad libitum (RFIneg), high-RFI pigs fed ad libitum (RFIpl) and high-RFI pigs restricted at RFIneg feeding level (RFIplR) to investigate the impact of feeding independently of selection. Three experimental conditions: low-RFI (RFIneg), high-RFI (RFIpl) and restricted-high RFI (RFIplR). 8 pigs per condition. One replicate per array.
