天山马鹿数量性状相关的统计分析

Correlation and Regression Analysis between Quantity Traits of Tianshan Red Deer (Cervus eluphus)

探讨了凉泉天山马鹿上锯公鹿的体重、茸重、茸的鲜干比例性状与鹿年龄、茸重性状与体重 ,体重、体尺和茸尺性状与茸重的关系。结果表明 :在一定年龄段 ,这些数量性状除了体尺中角基距性状与茸重呈强负相关 (-r,P <0 0 1 )外 ,多呈极显著正相关 (P <0 0 1 ) ,少数呈显著正相关 (P <0 0 5 ) ,并建立了线性回归方程 ,为预测并比较天山马鹿各锯时的体重、茸重、体尺、茸尺和茸的鲜干比例水平及制审定其检测标准提供了科学依据。

The relationships between ages and body weight, fresh antler weight and the ratio of dry antler and fresh antler weight; between fresh antler weight and body weight; between antler weight and body weight, body measurements and size of antler of Liangquan breed,Tianshan red deer were analysed Most of the measurements are positively correlated with antler weight ( P <0 05); a few measurements are negatively correlated with antler weight ( P <0 05); the distance between the bases of antler is negatively correlated with antler weight ( P <0 01) A regression equation was derived The results of the study can be used in predicting body weight, antler weight, body measurements antler size and dry antler yield of the deer at different ages
