Abstract: Songliao Black pig,as a premium crossbred variety of pigs in China,has unique genetic characteristics and economic value.Its breeding history can be traced back to the early 20th century.Songliao Black pig exhibits excellent adaptability and reproductive ability due to its prominent appearance features such as black fur,large ears and short legs.In terms of reproductive performance,Songliao Black pigs exhibit high conception rate and litter size.However,in terms of growth performance,although their growth rate and feed conversion rate are not as good as foreign breeds,their meat quality has obvious advantages,with delicious meat and moderate intramuscular fat content,which is highly favored by consumers.In recent years,the application of molecular biology technology has provided a new perspective for the study and breeding improvement of genetic characteristics in Songliao Black pigs.The author summarizes the breeding history,appearance characteristics,as well as the research progress in production performance,such as gene association analysis,the effects of dietary additives on growth and meat quality,and the progress in crossbreeding utilization of Songliao Black pigs.This review will provide theoretical supports that strengthen the protection and utilization of germplasm resource for promoting the sustainable development of special black pig industry.

Key words: Songliao Black pig; germplasm characteristics; breeding research; production performance; industrial development
