丹系猪及我国猪遗传育种的研究进展

Research Progress on Genetics and Breeding Programs in Danish and Chinese Pigs

丹麦养猪业技术先进、体系成熟,在各个方面都处于国际领先地位,因此丹麦是名副其实的养猪强国。随着高通量测序的日益成熟,成本逐渐降低,丹麦对丹系猪品种开展了大规模基因组选择育种,进一步加快了遗传进展,以提高其生产效益。本文主要从丹系猪品种起源与育种模式、重要经济性状的遗传机制挖掘与标记筛选、全基因组预测模型方法以及我国猪遗传育种研究进展等方面进行了总结,分析了目前丹系猪选择育种的现状、策略以及未来发展趋势,为提高我国猪生产性能提供理论基础和参考依据。

The Danish pig farming industry has the advanced technology and mature system in an international leading position in all aspects,so Denmark is a veritable pig farming country.With the gradual increasing maturity and decreasing cost of high-throughput sequencing,Denmark has carried out large-scale genome selective breeding of Danish pig breeds to further accelerate genetic progress and improve production efficiency.This review article mainly summarizes the origin and breeding mode of Danish pig breeds,the genetic mechanism revelation and marker identification of important economic traits,the genome-wide predictive model and method,and the research progress of Chinese pig genetic breeding,etc.The summarized aspects analyzed the current situation,strategy and future development trend of Danish pig selective breeding that aim to provide the theoretical and reference basis for improving pig production performance in our country.
