Aiming at an improvement of natural resistance, a selection of turkeys for high and low activity of lysozyme in serum was undertaken. The presented results are the preliminary evaluation of the first three generations (G0, G1, G2). The selected lines differed significantly in lysozyme activity, while no performance variations between the particular lines were found. A considerable influence of selection was observed in the birds livability in the first weeks of life. The mortality of poults after parents with a high lysozyme activity was nearly twice lower than that of poults after parents with a low activity.
