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.
