Chatenay Reproduction Center
Insemination & gynecological care
The gynecological care of a mare is a demanding undertaking, requiring consistency, availability, informed decision-making and, of course, in-depth expertise in the mastery of reproductive cycles.
It aims to optimize results, time spent at our center and the efficiency of gynecological interventions. At Centre de Reproduction de Chatenay, we are proud to place this delicate mission in the expert hands of our veterinary team, made up of world-renowned gynecologists entirely dedicated to our center.
Whatever the standard
Three protocols, one requirement.
Whether the stallion belongs to the BLH catalog or comes from another stud, the objective remains the same: to synchronize the mare's cycle with precision, preserve the quality of the semen and intervene in the best possible conditions.
Insemination with fresh "Beligneux Le Haras" semen
Fresh semen is essential. For our stud's stallions, collection is followed by insemination on site within ten minutes, guaranteeing optimum quality and maximizing the chances of conception.
Insemination with imported chilled semen
For Beligneux Le Haras studs and other catalogs, we import chilled semen. Our team ensures expert handling, preserves the quality of the semen, determines its grade and carries out insemination under ideal conditions from the moment it arrives.
Insemination with frozen semen
Frozen semen requires extra rigor. We carry out careful gynecological monitoring to synchronize insemination with ovulation, using a limited number of straws. The experience of our veterinarians guarantees precise execution, optimizing the chances of success.
Fertility results by cycle
differences in fertility.
Fertility varies according to seed type, storage method, time of use and precision of gynecological monitoring. These indicators summarize the references put forward for the Centre de Chatenay.
Fresh seed
Collection and insemination on site in a very short time.
Refrigerated seed
Reception, control and set-up on arrival at the center.
Frozen seed
Precise synchronization of ovulation and reasoned use of straws.
Laboratory focus
Clément prepares fresh seed for the Châtenay Center.
The control of fresh semen is based on a rapid and rigorous sequence: collection, inspection, preparation and insemination. This organization ensures maximum preservation of the biological quality of the semen before it is used.
Sanitary reception
Mare arrival procedures at the Châtenay Center.
At BLH, we never compromise on health and safety. All mares on site are vaccinated against influenza, tetanus and rhinopneumonitis. When they arrive, they must show no signs of contagious disease or fever.
If any of these conditions are not met, the mare will not be allowed to enter the gynecology room, or the facility. These strict rules not only offer you a guarantee of rigorous sanitary standards, but also testify to the vigilance with which we consider the health of the horses entrusted to us.
