However, strong selection mainly on growth and number of born alive decreased fitness and reduced environmental changes that animals can tolerate especially under suboptimal environments. Additional challenges are genetic differences between purebreds (selected animals) and crossbreds (commercial animals), and possibly different environments for these groups of animals. A successful genetic selection at this time requires comprehensive data for all levels of the pyramid, multitrait models for a variety of traits including categorical and survival, and software that can implement complicated models while supporting large data sets. Many projects in pig genetic evaluation are carried out at the University of Georgia. Those studies are supported by software family called BGF90.展开更多

It plays an important role in the maintenance of biological diversity. The genetic resources of wild boar can not only protect the genetic resources, but also improve the formation of new breeds in pigs. This paper summarized the advance on the main biological characteristics of wild boars, evolutionary origin between wild boars and domesticated pigs, and development and utilization of wild boars aimed to provide further insight into wild boar＇s genetic research and its resource protection.展开更多
