Journal of Dairy Science, 1961 Summary A method for estimating trend in genetic merit is described for a population consisting of animals sired by artificial insemination and of animals sired naturally. The contemporary comparison of unselected progeny of an artificially used sire and their naturally sired contemporaries making first records under the same conditions constitutes a
