[In vitro production of swine embryos]

In vitro production of transferable pig embryos is the key technology for an optimized utilization of high yielding farm animals, for the development of recent agricultural products and for the maintenance of genetic variability. Here we present research results of a recent larger study. Emphasis is on techniques to prepare sperm cells for IVF and to culture IVF-embryos in vitro up to blastocyst stages.
