PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email info@biomedcentral.com, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

seminal research on residual feed intake in poultry

I disagree with the following sentence in the paper Genetics Selection Evolution 2013, 45:26:
"Residual feed intake (RFI) was originally used in beef cattle by Koch et al. [4] and in poultry by Luiting [5]."

This statement is not correct. Results on Residual feed intake in poultry were first obtained and published by Philippe M��rat's group at INRA in the 1980's, about 10 years before Luiting's papers on RFI. See for example:

Bordas A, Merat P: Genetic-variation and phenotypic correlations of food-consumption of laying hens corrected for body-weight and production.Br Poult Sci 1981, 22:25-33

Merat P: Divergent selection for the residual component of feed consumption of laying hens independent of body weight and egg production: effects on body composition. Archiv F��r Gefl��gelkunde 1985, 4:158-160.

It is unfortunate that authors and referees missed these references.
