title: [Thermal homeostasis of the rabbit in thermoneutral zone (mathematic modeling)].
abstract: The thermal homeostasis of rabbits in thermoneutral zone were studied in the paper. Both in the experiment and in the model were shown that the temperature in the shell of the animal was changed without changing the core (nuclear) temperature when the temperature of the environment was changed and the heat production and delivery were remained unchanging. In the model was obtained this phenomenon was due to changing the shell and the core values, and was connected with blood flow variations in the shell. The latter mechanism was assessed as a principal one for active and quick regulation of the organism temperature and support of constant core temperature without significant and energy consumed is changing the heat production and delivery in thermoneutral zone of the mammalians. So, the thermoneutral zone is supported by the mechanism described, and the value of the thermoneutral zone is due to the shell size.
