摘要
对随机选择的32头(4窝)巴马小型猪0～25周期间每周平均体重进行测定,并用Logistic和Gompatz 2种模型对其进行拟合。结果表明:Logistic模型(R^2=0.997)和Gompatz模型(R^2=0.999)均能够对巴马小型猪的生长曲线进行良好的拟合,尤以Gompatz模型生长曲线预测的结果更接近实际情况。Gompatz模型预测的巴马小型猪早期生长速度的拐点周龄和拐点体重分别为18周和14.388 kg。
The average weekly body weight of 32 Bama miniature pigs randomly selected from 4 litters was measured during 0 - 25 weeks, and their growth curve was fitted by both logistic and Gompatz models. The results showed that their growth curve could be well fitted by both logistic mod- el（R2= 0. 997）and Gompatz model （R2 = 0. 999）, and the prediction by the Gompatz model-fitted growth curve better approached the actual value Bama miniature pigs＇early-stage growth curve was The Gompatz model-predicted inflexion point of 18 weeks in age and 14.388 kg in body weight.
