dc.description.abstract <p>Associations between egg production and feed efficiency and the genes of the major histocompatibility complex (MHC) of the chicken were investigated. Breeders were selected on the basis of indexes incorporating information on body weight and egg mass, with or without feed consumption information. Over 1,000 progeny were serotyped for the erythrocyte antigen B (Ea-B) after the 6th generation of selection. The <em>B</em>2 and <em>B</em>13 haplotypes accounted for over 75% of the <em>Ea-B</em> gene pool in all lines. Comparing each index-selected line with the control, <em>B</em>2 significantly increased in frequency at the expense of <em>B</em>13. This study further implicates MHC-linked genes as important in the physiology of growth and reproduction in the chicken.</p>
