Abstract

Previous results (Greaney, et al.,1991.) indicate that season of year has little effect on the response parameters of MOET although interactions between breed and season were recorded. Flocks within a breed have been selected for differences in seasonal lambing patterns based on ewe lambing date (Smith, et al.,1992). This trial reports the effects of this selection on the production and quality of embryos following superovulation at two times of the year as part of the cryogenic conservation process for these flocks.
