Germplasm Characteristics, Conservation and Various Utilization of Yunnan Local Pig Breeds

The pig breed resources are important strategic resources to ensure the safety and sustainable development of pig industry. Special and abundant local pig breed resources have been bred by the unique and diversified natural ecology, geographical, climatic environment and national farming customs, which provide the precious resources for cultivating new pig breeds (lines), developing high quality and characteristic pig production, and accelerating the sustainable development of pig industry. In order to provide some useful references for the scientific excavation, protection and utilization of local pig breed resources, this paper reviewed the research and practice advancements on the germplasm characteristics and genetic diversity, genetic basis of main economic traits, protection of the genetic resources, diversified breeding and utilization of Yunnan local pig breeds.
