	abstract = {New software, able to account for the impact of early selection on genetic variances and covariances, was used to evaluate two-stage sequential selection schemes for genetic gains in terminal sire flocks. The objective was to increase carcass lean and decrease carcass fat. Ultrasound scanning of both ram and ewe replacements was financially rewarding. There was little difference between autumn and spring scanning for rams. Ultrasound scanning was significantly more rewarding in the South Island Intensive situation than the North Island Hard Hill Country. The scale of rewards varied significantly with generation interval in the ram breeding flocks.},
