title: In vitro culture of silver fox embryos.
abstract: This experiment was designed to establish in vitro culture methods for silver fox embryos in order to develop the methods for evaluation of the post-thaw viability of frozen embryos in future studies. Artificially inseminated silver fox females were killed humanely on predetermined days after insemination and oviducts and uteri were flushed for embryos. The embryos were cultured in modified TCM 199 or in the same medium supplemented with silver fox oviductal tissue suspension for varying periods, from 6 days to 3 weeks. A total of 60 embryos was recovered. Only embryos beyond the 8-cell stage up to expanded blastocysts developed in vitro (28 % of all embryos). Early stage blastocysts developed most reliably and were of the best quality.
