Cluster of Chinese Indigenous Pig Breeds with 10 Economic Important Traits
摘要
Abstract
94 Chinese indigenous pig breeds and lines were clustered into 6 groups by a cluster analysis using the latest data of 10 traits of body size,reproductive performance,growth and carcass traits.The 6 groups were characterized by highest reproductive performance,fastest growth,best comprehensive performance,grada-tional type,highest dressing percentage and smallest body size,respectively.Because Qiandong spotted pig,Wei and Leping spotted pig had the smallest Euclidean distance with the average breed,they were considered as the central breeds.The Euclidean distance between Dongxiang spotted pig and Leping spotted pig was not close e-nough,and they were clustered into different groups. Therefore, it was unreasonable to consider them as the same type.The results of the cluster analysis paved a way to exploit and use the Chinese indigenous pig breeds.关键词
