摘  要:
根据761峰阿拉善双峰驼出生到15岁龄的体重资料,采用10种生长曲线,以年龄为单位拟合阿拉善双峰驼体重生长模型。结果显示:采用S曲线模型、三次项模型、对数模型和二次项模型的拟合骆驼体重生长曲线的效果都比较理想,拟合度均在0.9以上。S曲线模型拟合效果最好,公驼和母驼拟合度均在0.99左右。

Alashan camel; body weight; growth curve
摘  要:
Fitted the body weight growth curve model of Alashan Camel according to data from 761 Alashan Camel body weight with 10 different growth curve. Result show: The goodness of fitted the body weight growth curve model with S function model Y= e(b0 +b1/x)and Cubic function model Y= bo+b1×X+b2×X2+b3*X3and Logarithm function model Y= bo+ b1×(lnX)and Quadratic Y= bo+b1×X+b2×X2 was higher than 0.9. The best fitting goodness of the body weight growth curve was achieved when the curve was fitted with S function model Y=e(b0 +b1/x), which was up to 0.99 for female and male camels.
