Increased productivity and more efficient management of the ewe flock will enable the sheep industry to better compete with other livestock operations. Improved lambing percentage, decreased mortality of lambs from birth to weaning and a more uniform lamb crop will assure a greater return on ewe investment. Controlled breeding would achieve a shortened lambing period and a more uniform lamb crop. The better management necessary for a shortened, more rapid lambing may result in more lambs saved and marketed. More vigorous lambs and a lower death loss may be expected from crossbreeding and the use of antibiotics in the ewe ration at lambing time.
