Abstract
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.
期刊介绍：
Acta Agriculturæ Scandinavica, Section A – Animal Science publishes results of original research in animal science and their applications related to the following topics:
-Animal breeding and genetics
-Molecular genetics
-Animal physiology and reproduction
-Nutrition and feeding
-Animal behaviour and welfare
-General animal husbandry and systems of production, including economic and technical aspects
-Hygiene and quality of animal products
In addition to original articles, covering basic as well as applied subjects, the journal features review articles and short communications.
Acta Agriculturæ Scandinavica, Section A – Animal Science forms part of a trilogy of titles published on behalf of the Nordic Association of Agricultural Scientists (NJF). The series also includes Section B - Soil & Plant Science and the recently launched Section C - Food Economics .
Acta Agriculturae Scandinavica A, B and C are available to purchase as a combined subscription. This provides access to all three journals in the series, and is available to institutional subscribers only. For full pricing information, please view the Taylor & Francis Journals Price List here.
