| Özet |
| Growth patterns of Holstein cows in high altitude of Turkey were estimated by simple linear, quadratic, cubic models as linear in parameters and Brody, Bertalanffy, Logistic, Gompertz and Richards models as non-linear in parameters, and fitting accurracy of the models to age-weight data of Holstein were compared. Quadratic, Cubic, Brody, Bertalanffy, Logistic, Gompertz and Richards gave better fit to the data than the linear models. There were slight differences among these better fitting models in sum of squares explained by model. Non-linear models in the parameters gave the best fitting accuracy to dairy cattle data with the biological meaning of parameters. Cubic model can also be used for the purpose because of its simplicity and equal accuracy for fitting compared with non-linear model in the parameters. |
