Abstract
The aim of this work was to investigate the different responses of Japanese quails to different methods of inducing forced rest. The methods applied to force resting included qualitative and quantitative dietary procedures. In the First method different levels of dieta~y zinc and calcium were used, while in the second method a fasting regimen was applied. To achieve these goals two separate experiments were carried out on Japanese Quails at the end of their egg laying season (32-week of age and about 33% rate of laying).
