In dairy cattle, Rendel and Robertson (1950) estimated the annual genetic gain, considering that accuracy of prediction, selection intensity, and generation interval are different for four paths of selection: sires of bulls (SB), dams of bulls (DB), sires of cows (SC), and dams of cows (DC). Objectives of this study were to examine genetic selection differential (GSD) and generation interval (GI) that affect actual genetic gain per year and to predict genetic changes in the future for milk production of Holsteins in Hokkaido, Japan.
