Summary and Implications
Feed efficiency data from multiple generations of a brown egg layer line were analyzed with pedigree- and marker-based methods. Marker information improved accuracy of estimated breeding values (EBV), especially for long-term prediction. Several regions in the genome were found to be associated with feed consumption and efficiency.
