From foaling to gestation diagnosis, the team of Semilly's studfarm managed by his chief center, Richard Levallois, gives you all his competencies depending on your needs, with the insurance of his experience and reliability.
Your mare can be inseminated at Semilly's stufarm by any stallion available on the market. Of
course we practice inseminations with fresh, chilled or
frozen semen and we are also used to do deep inseminations
if necessary (when there are only few straws available, if mares
have some gynaecological problems, …). Gynaecological
and ovarian exams are conducted daily - or even several
times per day if needed, like in case of embryo transfer
or when only few straws are available or in other special
Since several years
is the center N°1 in France
Each year, more than 600 juments are inseminated at Semilly's studfarm .
Moreover, his qualitative results are also excellent. In fact, the official SIRE results gave us the percentage of the foals born upon the inseminations declared the year before by the AI centers. This percentage is of course smaller than the pregnancies rate because there are always some abortions or dead foals after birth. Anyway Semilly's studfarm presents a percentage of 70% of foals born upon the inseminations done the year before in his center, which is the best (which is excellent compare to the number of mares inseminated) !
The good reasons to do an transfert d’embryon with your mare
Have offspring with some mares who could have any themselves,
Avoid the risks of a gestation to an old mare or a mare who went on competition for several years and didn't foal yet,
Speed up the genetic progress by getting offspring with young mares which are tested on the shows at the same time,
Increase the production of a very good broodmare.
Ourselves we often practice embryo transfert for our breeding and produced this way many sport horses and stallions like : Eloïse de Semilly (2002 Jerez WEG) and Kalaska de Semilly (2008 Beijing OG) by the excellent Normandy Night who became old, Right Now Semilly (4YO vice-Champion of the Inter-Regional Show in Le Lion d’Angers 2009) by our CSI mare Jaffna de Semilly, Rock’N Roll Semilly (Champion of France of the 4 YO 2009) in order to get the bloodline of Oriele de la Mare, …

At the time that many
embryo transfer centres are starting up everywhere,
what are the assets which characterize Couvains Stud ?
Stud has been performing embryo transfer for more than
ten years. With our acquired knowledge and skill, we obtain
one of the best results in Europe. This expertise ensures
Working with an independent
society, we can ensure embryos “traceability”.
Our recipient mares are
carefully selected for optimum breeding characteristics.
We only choose mares that are sound, young, have already
foaled successfully at least once, and of good size and
body condition. Most are trotter or saddle mares, although
some are light draft mares. All of our mares are fed excellent
quality hay and supplements in order to leave nothing to
chance for the success of embryo transfers. As soon as
the pregnancy has been confirmed after 21 days gestation,
the receiving mares go to field in rich Norman pastures
which optimises embryos implantation and their good development
until the recipient mares departure.
We keep about 200 of recipient mares which are kept under artificial lights
during winter to allow an early start of the breeding season. We also give
to the breeders the possibility to keep going quite lately for the ones who
want to do an embryo transfer after the showjumping season.
