Selection programs in livestock species are becoming more and more efficient. New tools, such as molecular data used for genomic selection is accelerating how livestock breeds are evolving. Yet it is necessary to preserve the breeds’ genetic variability firstly because genetic progress is correlated to it, and any sudden increase of the inbreeding level can impact these populations in a negative way. Therefore it is necessary to regularly assess the genetic variability of both rare breeds and selected breeds in order to maintain their sustainability. Two types of data make it possible to calculate genetic variability indicators: pedigrees and genotyped data. For instance, thanks to these indicators, we can evaluate the impact of a major ancestor on the current population. The main goal of the VARUME project was to set up a genetic variability observatory for ruminant and equid breeds, in order to provide, on a regular basis, indicators that can assess the “genetic health” of the breeds, and that are agreed on by all the breed managers.
