Is it possible to differentiate meat products of a local breed from those of its sister breed based on genotypes?

To maintain endangered breeds and preserve their intrinsic diversity, it is often advocated to
develop derived labelled products and the related certification process. However, this
certification process is not always easily implemented if the endangered breed is closely
related to another one. The breed traceability is only possible if the genetic diversity between
those breeds is high enough. In this study, it was determined if meat of Dual-Purpose Blue
(DPB) animals can be differentiated from meat of its sister breed, the Beef Belgian Blue
(BBB), by the application of a genomic test. The results showed that the meat of DPB was
completely distinguished from the meat of BBB, and this, with a probability of one for all
meat samples. It therefore seemed possible to differentiate the DPB derived products from
those of BBB with a high accuracy, meaning the implementation in routine of a certification
process seemed possible.
