梅花鹿茸鲜重与年龄的相关性研究及经济效益分析

Studies on the Correlation between the Antler Weight and the Age of Sika Deer and on the Economic Performance of Sika Deer

以江苏地区的梅花鹿为对象,研究分析了梅花鹿鹿茸重量与其年龄之间的相关性。结果表明:9龄内梅花鹿的鹿茸重与年龄呈正相关(r=0.767,P<0.05),它们之间线性回归方程为y=0.345x+1.186。梅花鹿3～8锯的鲜茸单产很高,平均水平达3.28kg/锯。公鹿鲜茸重的变异系数在2～6龄之间逐渐减小,7龄之后又有上升的超势,其中以5～7龄的变异系数最小,分别为16.2%、6.1%、11.7%。相关数据分析表明,梅花鹿公鹿在1～4龄内经济效益较差,从5龄开始获利,年获利逐年增加,这种趋势与梅花鹿的茸产量变化趋势是一致的。

Sika deer in Jiangsr district were used as subject to study the correlation between the antler weight and the age of Sika deer.The results showed that andter yield(y)was linearly related with age(x)when the age of deer was less than9(y=0.345x+1.186,r =0.767,P <0.05).High antler yields of Sika deer,averaged3.28kg/saw,occurred during saw3to8.The Coefficient of Variation(CV)of antler weight decreased gradually from saw2to6and had a tendency to increase after saw7.From saw5to7,the CV of antler weight were16.2%,6.1%,and11.7%,respectively.In addition,economic performance of male Sika deer was poor when its age is less than4.After5years old,the male deer began to make a profit and the financial gain increased year after year,which was similar to the variation of the antler weight.
