title: [System analysis of the multi-oscillatory functional order in the circadian and ultradian frequency range and its monitoring value for load effects, exemplified by a varying light-dark regimen in the intensive rearing of sheep].
abstract: As part of the experiments to influence the annual rhythmicity of sexual reproduction, various artificial light-dark regimens were tested for their systemic effects. From the polygraphic registration of several functions, such as food ingestion, rumination, movement, cardiac and respiratory rhythm were obtained biorhythmometric system-analytic parameters of the multi-oscillatory functional order. Under well-balanced light-dark conditions (LD 13.5:10.5), a high intra- and interparametric degree of functional coupling of 80% is obtained, while under extreme conditions (LD 22:2) this value amounts to 39%, which is equivalent to a disorganized time structure and disturbed neuro-vegetative multi-oscillatory functional order. The significance of these or analogously contrived studies on environmental problems under human social conditions is pointed out.
