This study aimed at estimating tinamous growth curve using different models, and at verifying their goodness of fit.
A total number 11,639 weight records from 411 birds, being 6,671 from females and 3,095 from males, was analyzed.
The highest estimates of a parameter were obtained using Brody (BD), von Bertalanffy (VB), Gompertz (GP,) and Logistic function (LG).
Adult females were 5.7% heavier than males.
The highest estimates of b parameter were obtained in the LG, GP, BD, and VB models.
The estimated k parameter values in decreasing order were obtained in LG, GP, VB, and BD models.
The correlation between the parameters a and k showed heavier birds are less precocious than the lighter.
The estimates of intercept, linear regression coefficient, quadratic regression coefficient, and differences between quadratic c...
