摘　　要：【目的】研究焉耆马公马体尺生长发育状况，探讨其体尺生长发育模型，为焉耆马公马的科学饲养和育种提供数据参考。【方法】对252匹0～10岁焉耆马公马进行体高、体长、胸围和管围进行测定，并进行差异性分析和Logistic、VonBertalanffy及Gompertz3种生长曲线拟合。【结果】体高、体长、胸围及管围随着年龄的增长呈现极显著或显著的差异性（P〈0．01或P〈0．05）；对体高、体长、胸围及管围生长曲线进行拟合，拟合曲线较好，拟合度均在0．86以上。【结论】VonBertalanffy回归曲线拟合度最高，对焉耆马公马的实际生产具有一定的指导价值。[ Objective ] This paper aims to study the growth and development of Yanqi stallion, and hold a preliminary discussion about the growth curve model in the hope of providing a basis for scientific feeding management and breeding improvement. [ Method] 252 Yanqi stallion was chosen, which was from 0 to 10 years old, to detect the body height, body length, heart girth and cannon circumference. The growth curve of Yanqi stallion was analyzed with three kinds of nonlinear models （ Logistic, Von Bertalanffy and Gompertz）. [ Result] The results showed that the extremely significantly or significantly difference of the body height, body length, heart girth and cannon circumference by the age （ P 〈 0.01 or P 〈 0.05 ）. This experience showed that the growth curves of the body height, body length and heart girth and cannon circumference were appropriately fitted with Logistic, Von Bertalanffy and Gompertz models, the degree of fitting R2 were higher than 0.86. [Conclusion]The Von Bertalanffy model had the best effect on fitting with the growth curves of Yanqi stallion. This study had the certain reference value to the actual production.
