| Abstract: | 1. Both living and model animals were used to evaluate the significance of a sleeping plate as a thermal protection for the farmed raccoon dog (Nyctereutes procyonoides, Gray, 1834), its use by the animals and its cleanliness while used. 2. A dry sleeping plate effectively prevented heat loss from the model animal while a wet plate was less effective. The degree of heat transfer was highest when the plate was ice-covered. Heat loss in windy conditions was significantly higher than in calm conditions. 3. The use of a sleeping plate did not depend on ambient air temperature; in spite of the cold weather (about -25 degrees C) only one in four animals preferred to lie on plate. Animals which did not prefer to use sleeping plates most eagerly messed them up. |
