“…2006a and this study) and farmed polecats/ferrets (Enders and Schlafke 1972; Lindeberg 2003) occurs on day 12 of pregnancy, and the rates of embryonic development are similar (Lindeberg and Järvinen 2003; Amstislavsky et al. 2006a), there has been a consistent failure in successfully producing kits from interspecies embryo transfer between these two species of mustelids (Amstislavsky et al. 2006b).…”

“…This has been reported earlier by Moshonkin (1981), and both studies indicate that the period between the first and the second oestrus is approximately 1 month. Re-entry to oestrus has also been observed even following embryo removal by flushing (Amstislavsky et al 2006b), thereby providing a valuable means to expand European mink numbers by transfer of embryos from genetically superior females to hybrid honorik ⁄ nohorik recipient females.…”

“…Methods for embryo collection have been recently adapted to European mink and the transfer of fresh European mink embryos to hybrids (between European mink and European polecats) was successfully performed (Amstislavsky et al 2004(Amstislavsky et al , 2006a. However, attempts to undertake straightforward embryo transfer between European mink and European polecat have failed, no positive outcome of this interspecies transfer has been detected so far (Amstislavsky et al 2006b) despite the close genetic similarity existing between these species (Grafodatsky 1976;Davison et al 2000;Sato et al 2003) and the similar duration of pregnancy (Ternovsky and Ternovskaya 1994).…”

Despite efforts undertaken to conserve the endangered European mink, its reproduction is still poorly studied. The aim was to study its reproductive cyclicity, faecal progesterone concentration and ovarian changes during early pregnancy, with the emphasis on the pre-implantation period and implantation. During the 2004 breeding season, oestrous cycle was monitored in 39 females as well as ovarian changes during early pregnancy in 22 females. During the 2007 breeding season, faecal progesterone concentration measured by radioimmunoassay was monitored during pregnancy in 10 females throughout their pregnancy. The breeding season 2004 started on March 18 and ended on May 10, with the peak recorded in April. The duration of first oestrus was 1-12 days. If not mated, the vast majority of females entered second oestrus after 12-55 days. In general, relatively low faecal progesterone values were detected in European mink; an average of 42.69 +/- 4.70 ng/g faeces in oestrous females with a maximum of 176.44 +/- 23.01 ng/g faeces on pregnancy day 12. anova indicated a significant effect of the pregnancy stage. Post hoc comparisons with Fisher least significant difference (LSD) test revealed that faecal progesterone concentrations on days 8 and 12 post coitum (p.c.), but not at the end of pregnancy (day 40), were higher when compared with the initial oestrous level. Implantation in this species occurs on day 12 p.c. and was indicated by prominent uterine swellings and failure to flush the uterine horns beyond this day. Advanced luteogenesis was observed with prominent corpora lutea found in ovaries around the time of implantation. To conclude, European mink is a seasonally polyoestrous species; the early pregnancy of European mink resembles that of European polecat, i.e. in both species, implantation occurs on day 12 p.c. without any implantation delay.

“…This, together with the use of polecats as a species for method testing, led to the development of an embryo freezing protocol applicable to mustelids (Lindeberg 2003; Lindeberg et al. 2003; Amstislavsky et al. 2006b), thereby opening the possibility of embryo cryobanking and embryo transfer towards the preservation of the genetic diversity of European mink.…”

The European mink (Mustela lutreola) is a small mammal, which belongs to the Mustelidae family (Carnivora). Earlier, the range of distribution of this species encompassed much of the European continent. During the 20th century, the numbers of European mink declined and the range of its distribution became reduced to three fragmented populations; today this species faces extinction. The urgent necessity for effective conservation efforts to protect the European mink is accepted by the governmental organizations as well as scientific communities of most European countries. In this paper, the reasons for the disappearance of European mink are reviewed and results of past conservation efforts based on captive breeding and reintroduction programmes are critically evaluated in the broad context of modern concepts of conservation genetics and reproductive biology. The data recently obtained on the reproduction and pre-implantation development of European mink and the prospects of incorporation of modern reproductive technologies into the conservation programme of this species are discussed.
