摘要
2005年5月,对北京南海子麋鹿苑1岁到5岁5个不同年龄阶段33头雌性麋鹿的体重(BW)、肩高(H)、头长(HL)、耳长(EL)、胸围(BR)、尾长(TL)、体长(BL)、后足长(ZL)进行测量,分别对体重与其余7项体尺性状进行相关分析和主成分分析。结果表明,在不同年龄阶段,雌鹿的7个体尺和体重性状之间存在着不同程度的相关性,其中体重与胸围、肩高和体长相关性较大。在1至2岁雌性麋鹿,体重增长速度较快,2岁为麋鹿外貌定型阶段,3～4岁麋鹿的性状第一主成分相似,说明雌性麋鹿的体成熟期是在3～4岁。
Correlations between body weight and each of other 7 body measurements ： shoulder height, head length, ear length, chest girth, tail length, body length, and hind leg length of 33 female milus of 1 to 5 years old in Milu Park of Beijing were calculated and the data were analyzed with principal component analysis. The results showed that there were direct correlations of different levels between body weight and all the body measurement traits. Female milu grew fast during 1 to 2 years old, and reached physical maturity at age of 3 to 4 years old.
