Using a method of telemetrical electrocardiography 40 young domesticated moose were studied in conditions approximating the natural environment at the experimental moose farm in the Pechora-Ilych Nature Reserve. An environmental physiological estimation of the ontogeny of the behavioural and emotional reactions of moose calves was done. The cardiac rhythm stabilization at value characteristic for adult animals occurred at the age of approximately 3 months. Young moose motions such as walking or pasture increased heart rate by 30-50%. Emotional positive and negative reactions are attended by cardiac chronotropic effect. The most pronounced heart rate increment (up to 250 beats per minute) was found at nursing.
