Genomics and sexed semen in dairy cattle

Claire Ponsart’s area of research concerns animal breeding and artificial insemination. After being qualified as a veterinarian, her PhD thesis was dedicated to the use of flushing as a means to improve cyclicity resumption in beef cattle. She joined France’s UNCEIA Research and Development department in 1998 with the responsibility of leading projects related to embryo production in cattle. In 2002, she was chosen to implement new practical tools in French breeding companies, aiming to improve fertility within the UNCEIA Research and Development project called “Fertility at First”. Thus, Claire is interested in reproduction management, specifically looking at ways to achieve fertility improvement together with genetic selection.

Since 2012, Claire was appointed Director of the National Laboratory for Health Controls in Breeding Stock (Laboratoire National de Contrôle des Reproducteurs, LNCR) involving pathogens related to the genital tract and management of sanitary status in AI centres and ET stations.
