A large-scale screening operation over two seasons by Landcorp Farming Ltd has established a terminal sire-breeding programme for sheep. Within the North and South Islands, screened hoggets were transferred to Huirimu Station and Kepler Station respectively. In 1989, 2,046 ewe hoggets (0.8%) were screened on liveweight from 248,500 animals in 114 flocks. Mean pooled population weight (adjusted to 18 December) was 43.2
