Conteúdo: | In 1984 selected Oxford Down (0) and Texel (T) sheep in Denmark and T and Finnish Landrace (F) sheep in Finland were purchased or leased and thenassembled for treatment. The ewes were synchronised and superovulated before being subjected to surgical embryo recovery. Recovered embryos with at least 8 cells and an intact zona pellucida were then deep frozen. The mean ovulation rate, number ofeggs recovered and embryos frozen from the 0 and Tin Denmark were 5.4, 4.4, 1.5 and 7.1, 5.0 and 3.0, respectively. Results for T and F in Finland were 7.5, 4.9, 4. I and 10.0. 7.0 and 5.8. respectively. A total of 548 embryos was imported into New Zealand. Two-hundred and twenty embryos were thawed and transferred to Coopworth recipients in March and 46 in May 1985. The percentages ofembryos surviving to term for the various breeds in March and May were: Denmark 0,43 and 20; Denmark T, 59 and 7; Finland T, 59 and 55; Finland F, 64 and 50, rcsepctively. Thirty-two Coopworths were inseminated with thawed Fsperm deposited via endoscopy and 24 (75%) lambed producing 28 lambs. The importation of both embryos and semen was very successful.
