Principal Component Analysis on the Slaughtering Performance of Anas Platyrhynchos

YANG Jun,TANG Deng-hua,LUO Jia-qin (College of Animal Science,Yangtze University,Jingzhou 434025,China)  
Principal component analysis was carried out to study the slaughtering performance of cross combinations using Anas platyrhynchos as male parent.The results showed that six traits were combined into three independent principal components with an accumulating contribution rate of 94.95%,which could totally reflect the information of the original traits.Comprehensive assessment showed that the combination LBLY containing 1/2 Anas platyrhynchos blood, 1/4 Peking Duck blood and 1/4 Cherry Valley Duck blood was the best among three cross combinations.
