Mono and Multiphasic Analysis of Growth Curves Selected of a Japanese Quail Line at 5-Week's Body Weight

Authors: HANDAN ÇAMDEVİREN, BAHAR TAŞDELEN

Abstract: In this research, monophasic, diphasic and triphasic logistic growth curve functions used to introduce the growing of the body weight in Japanese quail (Coturnix japonica) are presented. In male and female Japanese quail, the diphasic growth curve fits better than the other growth curves because of residual variance, autocorrelation and determination coefficients. In addition, the diphasic growth function is compared with the monophasic growth function to study the relationship between these two approaches for describing growth curves.
