【摘要】 采用逐步回归的方法对随机抽取的45只0.5岁龄东北虎的体重和5个主要体尺指标进行了回归分析,得到0.5岁龄东北虎体重和体尺指标的最优回归方程为:W=-40.9314+0.3983L+0.7490S+0.2761A-0.2569C-0.0375T(♂)、W=-59.5255+0.7150L+0.2461S+0.1953A-0.0086C-0.1729T(♀),明确了0.5岁龄东北虎体重与体尺指标的关系,为东北虎的选育工作提供参考。更多还原

【Abstract】 By the stepwise regression method,the regression analysis was conducted between the body weight and 5 body measurements of 45 Amur tigers of 0.5 year old sampled randomly and the optimum regression equation was obtained as follow,W=-40.9314 +0.3983L +0.7490S+0.2761A-0.2569C-0.0375T(♂),W=-59.5255+0.7150L+0.2461S+0.1953A-0.0086C-0.1729T(♀),The relationship between the body weight and body measurement has been made certain and result could be used as a reference information for selection and breeding Amur tiger in future.更多还原
