This study was undertaken to apply non-linear mixed effects model to examine the effect of short-term selection for 8-week body weight on growth parameters in divergently selected lines of Japanese quail and their controls. The parameters of Richards models were utilized to describe growth pattern of Japanese quails from the generation 5 including growth curves; and absolute and relative growth rates.
