The research carried out by authors aimed at inventing the sensitive non-invasive method for ethical investigation into the influence of chemical substances and physical factors on the growth of organisms in the prenatal phase. The knowledge of effects of chemical substances on the course of embryogenesis provides the possibility of testing new medicines and assessing the teratogenous influence of chemical substances already present in the natural environment on alive organisms. The results of the research are presented in the form of the series of two papers under the same title. The first paper, denoted as the part I, concerns the invented noninvasive method dedicated for measurements of low-amplitude vibrations induced by the work of cardiac muscles. The current paper (part II) is dedicated to vibration analysis of measured ballistocardiograps carried out by means of the classical LSCE modal analysis method. Due to the rapid increase in the cardiac muscle mass, the parameters of the biomechanical model of developing avian embryo are nonlinear. Nevertheless in a single measurement session the changes in the object parameters are negligible, which enables application of the classical modal analysis methods.
