The relationship between heat stress, meat quality, and residual feed intake (RFI) is unknown in growing steers. To address this issue, high RFI (HRFI) and low RFI (LRFI) individuals were compared by assessing RFI in 48 Angus-sired steers during a 70-d feeding trial conducted during July through September to identify steers with calculated RFI at least 2 SD apart. The association of RFI with in...

Mechanisms underlying variation in residual feed intake (RFI), a heritable feed efficiency measure, are poorly understood while the relationship between RFI and meat quality is uncertain. To address these issues, 2 divergent cohorts consisting of High (HRFI) and Low (LRFI) RFI individuals were created by assessing RFI in 48 Angus-sired steers during a 70 d feeding trial to identify steers with ...

The prolactin-releasing peptide receptor (PrRPR) and its bioactive RF-amide peptide (PrRP20) have been investigated to explore the ligand binding mode of peptide Gprotein coupled receptors (GPCR). By receptor mutagenesis we identified the conserved aspartate in the upper part of transmembrane helix 6 (D) of the receptor as the first position that directly interacts with arginine 19 of the ligan...
