摘要： 为了解闽南火鸡的生长发育规律，对不同性别火鸡生长曲线选择较为适宜的拟合方程，比较公、母火鸡生长模式差异。本研究运用Logistic、Gompertz和Von Bertalanffy 3种非线性生长模型对不同性别的福建闽南火鸡0~8月龄体重生长数据进行曲线拟合和分析。结果表明：3种模型均能较好的模拟闽南火鸡的生长曲线，拟合度(R2)均达0.992以上，其中以Gompertz生长曲线拟合效果最佳，公、母火鸡拟合度均为0.997；公、母火鸡的拐点月龄分别为4.26、2.63月，拐点体重分别为2799.40、1266.67 g，最大月增重分别为929.40、587.73 g。利用 Gompertz 生长曲线拟合闽南火鸡各种指标能够揭示其生长规律，较好地掌握不同性别闽南火鸡生长过程的特性，结果为确定不同时期饲料最佳用量、实施科学的饲养管理提供参考信息。

Abstract: In order to research the growth and development of the law of Taiwanese turkey, we choose a more suitable fitting equation turkey growth curves for different genders, compare male and female turkeys differences in growth patterns. This study applies Logistic, Gompertz and Von Bertalanffy these three kinds of nonlinear growth models to fit and analyze for growth data curve of different gender Minnan Turkey's 0-8 month-old weight. The results showed that all these three kinds of models can simulate Minnan Turkey's growth curve, the values of R2 were more than 0.992, Gompertz showed the best fitting efficiency, especially its cock and hen's fitness reach to 0.997; Cock's and hen's growth inflection point were 4.26、2.63 month-old, weight inflection point is 2799.40 Gram, 1266.67 Gram and its maximum month weight gain is 929.40 Gram, 587.73 Gram. Using Gompertz growth curve to fit all Minnan Turkey's index can reveal its growth rule and master its growth character of different gender in different growth periods, therefore it can offer reference information for determining best proper amount in different feeding periods and implement scientific feeding management.
