摘要: 选用湘黄母鸡90只,测定140日龄前的体重、体尺(体斜长、胸宽、胫骨长),并对各指标进行生长曲线拟合。结果表明,Logistic模型和Gompertz模型均能很好地拟合出湘黄鸡各指标的生长曲线。对于体重,无论是拟合度还是实测值与估计值的比较,均显示Gompertz生长曲线拟合更优;而对体尺而言,则认为用Logistic模型拟合更合适。

Abstract: A total of 90 Hunan yellow hens at 140 days old were selected.The body weight and body size(body length,chest width and tibia length) were determined.Growth curve fitting was performed.The results showed that the Logistic model and the Gompertz model well fit the growth curve of Hunan yellow hens.The fitting degree and accordance between measured values and estimated values of body weight better fit the Gompertz model,but those of body size better fit the Logistic model.
