【摘要】 研究旨在探究塔里木鸽、白卡奴鸽乳鸽的生长发育规律，选择最佳的生长曲线模型。试验分别测定塔里木鸽和白卡奴鸽其0～4周龄体重、体尺指标并进行相关性分析，通过Logistic、Gompertz和Von Bertalanffy 3种模型拟合其生长曲线。结果显示：在体重体尺比较方面，4周龄时，白卡奴鸽乳鸽优于塔里木鸽（P<0.01）。在生长曲线拟合方面，Gompertz模型对塔里木鸽和白卡奴鸽拟合效果较佳。在体重体尺相关性方面，除了白卡奴鸽的2周龄外，塔里木鸽和白卡奴鸽的体重均与其体斜长达到极显著水平（P<0.01），因此建议将体斜长作为两种鸽早期体重选育的一个辅助指标。综上所述，Gompertz模型是塔里木鸽和白卡奴鸽的最适生长曲线拟合模型，可将体斜长作为塔里木鸽和白卡奴鸽早期体重选育的辅助指标。更多还原

【Abstract】 The study aimed to investigate the growth and development rules of young pigeons of Tarim pigeon and Carneau pigeon, and to select the optimal growth curve model. In this experiment, Tarim pigeon and Carneau pigeon were used as the research subjects. The body weights and body size indices of pigeons from 0 to 4 weeks old were measured respectively, and a correlation analysis was carried out. The growth curves were fitted using three models: Logistic, Gompertz, and Von Bertalanffy. The results showed that in terms of the comparison of body weight and body size, the young Carneau pigeon were superior to those of Tarim pigeons at 4 weeks of age. Regarding the fitting of growth curves, the Gompertz model showed the best fitting effect for both Tarim pigeons and Carneau pigeons. In terms of the correlation between body weight and body size, except for the Carneau pigeons at 2 weeks of age, the body weights of Tarim pigeon and Carneau pigeon were highly significantly correlated with their body diagonal lengths(P<0.01). Therefore, it is recommended that the body diagonal length be used as an auxiliary index for the early-stage body weight selection and breeding of these two types of pigeons. In summary, the Gompertz model was the better growth curve fitting model for Tarim pigeon and Carneau pigeon, and the body diagonal length could be regarded as an auxiliary index for the early-stage body weight selection and breeding of these two kinds of pigeons.更多还原
