2 Between research and genetic improvement Initially derived from an INRA blood group lab, it was transformed in 1994 into a company to expand its activities LABOGENA is a commercial DNA genotyping lab, owned by INRA (43,3%) and its main customers of different species (particularly cattle, horse, and sheep) animal industry partners 40 years service activities in the genetics field 2004 MYB - LABOGENA 2
