Abstract

In another publication the writer pointed out that five generations of selection for resistance to fowl typhoid in the chicken resulted in a decided decrease in the mortality of the selected stocks. Specifically, the effect of the selection was to decrease the mortality from approximately 85 percent in the unselected parental stock to slightly more than 10 percent in the fifth selected generation.
