The number of lambs marketed per ewe exposed has the greatest effect, of many factors studied including individual lamb weight, on the total weight of lamb marketed per ewe per year. Various approaches have been attempted to increase the number of lambs born per ewe lambing. Management techniques such as flushing, time of breeding and hormone therapy have all yielded success within moderate limits. The most successful approach at increasing lambing rate on a permanent basis has been by selection of appropriate breeds and/or their crosses. Although this has resulted in increased ovulations and birth rates, little information is available on total lifetime production in South Dakota. The purpose of this study was to evaluate a crossbred ewe (FDT) developed for potential high productivity under farm or range conditions found in South Dakota.
