Abstract

The purpose of this study was to demonstrate the effects of 11 generations of divergent selection on 5-week body weight in Japanese quail on both phenotypic and genetic variations of parameters of the Richards growth model. In total, 589 birds from a high body weight line (HL), a low body weight line (LL) and a random bred control line (C) were used in the study.
