Investigation on genetic resources of Gaoligongshan pig.

The Gaoligongshan pig is one of the rare indigenous breeds in Yunnan province,which mainly distributes around on Nujiang autonomous prefecture locating in Gaoligongshan range in the northwestern of Yunnan.This pig breed,characterized by small body size,slower growth,low litter size and good meat quality,has adapted well to bad natural environment and extensive feeding.Since the Gaoligongshan pig breed is mainly found in minority areas with bad natural environment,underdeveloped social-economic conditions and inconvenient transportation,little attention was paid to this animal in the past.During 2006 to 2008,three times investigations have been made into Gaoligongshan pig breeding in Nujiang autonomous prefecture,meanwhile,the slaughtering,carcass composition and meat quality of this pig breed have been measured.The goal of the study is to fully grasp,exhume the unique germplasm traits of Gaoligongshan pig as well as to provide scientific basis for the protection,exploitation and utilization of this pig breed.
