    Abstract: In this study, results showed that study six indexes were 
  synthesized two composite indexes by Principal Component Analysis (PCA) on egg 
  quality characteristics of Chinese native duck breeds, the first 2 principal 
  components accounted for 65.320% of total variation using principal component 
  analysis. It represented the information of the original indicators.
