| Abstract: | 14 traits relative to body size of 55 firstborn deer were measured and analysed by cluster and principal component analysis to study the relationship of each trait.The results showed that all traits could be divided into 4 kinds of factors,such as chest,croup,head and tail according to similarity of traits and some representative traits including body weight,chest girth,body length,body height,croup width,head width,tail length were selected by this way. |
| Keywords: | firstborn deer body sizes body weight cluster analysis principal component analysis |
