 Most national populations of White Park cattle have been DNA tested to verify parentage, to confirm the provenance of products, and to enable assignment of applicant animals to breed and determine the optimum breeding program to ensure their effective conservation survival.The breeding program in the UK aims to increase the desirable characteristics of the breed while maintaining genetic diversity, as heterogeneity is low due to inbreeding through much of the twentieth century.Faygate Brace (born 1906) contributed of the ancestry of the breed by the 1940s, and Whipsnade 281 (born 1956) repeated this pattern in the second half of the twentieth century.
