Breed assignment was performed for pigs putatively belonging to Pied Danish Pigs, an endangered Danish conservation breed. DNA array data were available for the candidates who had insufficient pedigree information. So were data for a reference population of animals from Danish conservation breeds as well as data from a range of Northern European pig breeds, and wild boar. Breed proportions were estimated using the program ADMIXTURE. Half the candidates were found to have at least 95% of their ancestry from Pied Danish Pigs. Several candidates showed varying degrees of admixture with other breeds, most notably Gloucester Old Spot. The same was observed for several of the Pied Danish Pig reference animals. The analyzes identified suitable breeding candidates and prevented unwanted recent admixture from spreading in the breeding population.

对假定属于丹麦濒危保护品种Pied Danish Pigs的猪进行了品种分配。DNA谱系数据可用于谱系信息不足的候选人。来自丹麦保护品种的参考动物种群数据以及一系列北欧猪品种和野猪的数据也是如此。使用程序ADMIXTURE估算品种比例。发现一半候选人的血统至少有95％来自丹麦猪。几位候选人显示出与其他品种的混合程度不同，最著名的是格洛斯特老斑点。在一些丹麦小猪参考动物中也观察到了同样的情况。这些分析确定了合适的育种候选对象，并防止了不必要的近期混合物在育种种群中扩散。
