Advances in understanding the genetics of sow prolificacy: reproductive performance, trade-offs, and management solutions
摘要
The domestication of the wild boar (Sus scrofa), about 10 000 years ago, marked the start of genetic improvement in pigs. This was followed by the selection of pigs (Sus scrofa domesticus) for specific traits, giving rise to a host of domestic breeds with different physical, behavioral, physiological, and reproductive characteristics (Dekkers et al., 2011).
