人工哺育猎豹幼仔体重和体尺相关性

The Regression Analysis between Body Weight and Body Measurement of Younger Cheetah

采用多元统计分析方法对人工饲养的44头幼猎豹(Acinonyx jubatus)生长发育规律展开研究。研究结果显示,体重和体尺等相关指标,雄性猎豹都比雌性猎豹发育较快,提示在饲养过程中需要注意公、母猎豹生长速度差异所造成的营养需要量的不同;相关分析显示雌雄幼猎豹体重和体尺资料都成显著的正相关;通过体重和6个主要体尺指标的回归分析,得到雄、雌幼猎豹体重和体尺指标的最优回归方程分别为:W=-3019.648-4.888L-62.973C+77.181T+127.625A-153.310F+194.038H,W=-4147.921+56.533L+29.301C-68.212T+87.033A+76.012F+29.517H,该方程明确了幼猎豹体重与体尺指标的关系,为猎豹的选育工作提供了参考。

The present study investigated the low of the growth and development of the 44 young cheetah （Acinonyx jubatus） by statistic aralysiso The findings showed that, male than female cheetah rapid development for weight-related indicators such as body size, In need of attention, the cheetah growth rate caused by the difference in the nutritional requirements of different sexuad cheetah. The correlation analysis shows that weight and body size of data is a significant positive correlation,which indioted the existence of strong interal relatoons. The regression analysis was conducted between the body weight and 6 body measurements of younger cheetah by regression analysis method. The optimum regression equations were obtained as follow： W=-3019.648-.4.888L-62.973C＋77.181T＋ 127.625A-153.310F＋194.038H, W=-4147.921＋56.533L＋29.301C-68.212T＋87.033A ＋76.012F＋29.517H. The relationship between the body weight and body measurement has been made certain and the results could be used as a reference information for selection and breeding of cheetah in the future.
