摘要

对被推定为丹麦花斑猪(一种濒临灭绝的丹麦保护品种)的猪进行了品种分配。家谱信息不充分的候选人可获得DNA阵列数据。丹麦保护品种的参考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ADMIXTURE程序估算品种比例。研究发现，一半的候选人至少有95%的祖先来自丹麦花斑猪。几个候选品种表现出不同程度的与其他品种的混合，最明显的是格洛斯特老斑。同样的情况也发生在丹麦花斑猪的几种参考动物身上。分析确定了合适的候选育种品种，并防止了不想要的新混合物在育种群体中传播。

Genomic assessment of suitability of pigs for inclusion in the Pied Danish Pig conservation program – A case study

ABSTRACT 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.
