Livestock diversity

INRA is actively involved in preserving and characterising livestock genetic resources. Lines that have unique characteristics are selected and maintained in INRA’s experimental units. Some of these lines are sold to breeders, while others are used as biomedical models or as models for studying biological functions. Below is a list of the lines studied and maintained in the Animal Genetics Division. Some of these lines are or will be made available to the national cryobank, which works in partnership with INRA.
