N2 - Fatty acid (FA) composition was analysed in unincubated eggs of 200 hens. The birds were either from lines (RIR, line 33, SS, line 44) and crosses where feed efficiency of egg-mass production had been improved over eight to nine generations of reciprocal recurrent selection, or from a control population. The somewhat more efficient line 33 had less saturated FA (SAT FA), but a higher ratio for PUFA (polyunsaturated FA)/SAT. Selection decreased SAT FA but increased PUFA/SAT, and heterosis acted in the same direction. Thus it appears that modern poultry breeding affects egg composition in a dietary desirable direction.
