Abstract
Genomic selection using high-density SNP panels was first implemented in dairy cattle breeding programs. It provided benefits in terms of reduced generation intervals, improved accuracies of selecting young animals, and reductions in costs associated with the requirement of progeny testing bulls in traditional breeding programs (Hayes et al., 2009). Several distinct features of the poultry breeding industry differ markedly from dairy cattle breeding and influence the manner in which genomic selection can be used for genetic improvement in poultry breeding: · Traditional genetic improvement programs in poultry already have short generation intervals (multiple overlapping generations per year with selection every 6 wk in broilers, non-overlapping annual generations in layers). There is some scope for shortening the generation interval in layers but not as much as was the case for dairy cattle breeding where bull pathways could be reduced in length from greater than 6 yr to less than 3 yr (Schaeffer, 2006, Schefers and Weigel, 2012).
期刊介绍:
Animal Frontiers is the official journal of the following globally active professional animal science societies:
ASAS, the American Society of Animal Science
CSAS, the Canadian Society of Animal Science
EAAP, the European Federation of Animal Science
AMSA, the American Meat Science Association
These organizations are dedicated to the advancement and dissemination of science-based knowledge concerning animal agriculture. Animal Frontiers provides a novel forum for innovative and timely perspectives that have relevance to understanding the complex dynamics at work through animal agriculture. Animal Frontiers publishes discussion and position papers that present several international perspectives on the status of high-impact, global issues in animal agriculture. Every issue will explore a theme of broad and current interest within animal science and animal agriculture.
