is an effective tool for shaping a herd and meeting your breeding objectives. Our ambition here is to select the best breeding stock to produce the best offspring.
Several selection methods :
Quality is AURIVA’s sole objective
Dairy or suckling breeds, size of reference populations, available data and technologies… the selection processes for each breed are not identical.
Although indexes (genetic values enabling comparison and overall assessment of each bull) are published for evaluated traits, they are not all obtained in the same way. Reflecting the diversity of French livestock, the multiplicity of these territories and the plurality of breeding methods, our breeding programs use all the technical innovations at their disposal, as well as methods that have been tried and tested for decades.
Today and tomorrow genetic progress
- The progression of already known traits, widely used in all breeds or currently being deployed in some.
- The emergence and perpetuation of new characteristics that will make the difference tomorrow. Thanks to a proactive R&D policy, we are working to identify genetic markers whose heritability or impact will help your herds to progress in a number of areas: performance and income, working comfort, animal hardiness, animal welfare and environmental impact.
How does AURIVA select the best bulls?
Directed couplings and biotechnologies
Phenotyping and/or genotyping
Progeny testing: the reliability of the Blond program.
Unique in the world, in the Blonde d’Aquitaine breed, the genetic value of genotyped bulls selected following Individual Control or Breed Station Control and Sexual Function is measured by a large-scale progeny evaluation.
Their genetic value will be confirmed by the performance of their sons and daughters. This progeny test is carried out at the Casteljaloux station.
Since 2012, AURIVA-Elevage has also carried out on-farm weaning evaluations to offer an ever more complete panel of bulls. Young bulls in the program are evaluated on the performance of their progeny at weaning, in addition to the bulls involved in the Maternal Qualities evaluation at the station.
The Aubrac, Gasconne and Bazadaise breeds are also subject to on-farm IBOVAL progeny evaluation, first at weaning and then for maternal traits.
This attention to testing, and thus to the reliability of the indexes issued, is one of the pillars that enable us to offer you a superior level of quality for the renewal of your livestock.

detailed presentation of all selection programs
The single-step system introduced in 2022 for dairy breeds will also be rolled out for all suckling breeds in 2024.
Developed by the various players in French and international genetics, the single step allows indexes to be calculated in a single step, harmonized internationally, corrected for genetic progress and all genotyping data to be taken into account.
