Özet:
Non-linear Logistic, Gompertz and Richards growth curve models were fitted to the
data from Simmental x Southern Anatolian Red (SAR) crossbred cattles. Individual
growth curves were fitted based on live weight measurements, and then general growth
curves were obtained for all the models.
In addition, Bernstein basis polynomials have played important roles in
nonparametric curve estimation. Therefore, Bernstein polynomial approach was used to
model the growth curve in the current data. We determined the accuracy of the models by
using coefficient of determination 2 R , mean square error (MSE) and iteration number
together.
In summary, the most suitable model based on the accuracy criteria was Bernstein
model. Among the well-known growth curves, Logistic, Richards and Gompertz were
ordered respectively.
