The influence of various ranges of dry cooling /average 22,1 mW/cm² - BCD and 60,2 aW/cm² - CD/ on the heat management have been studied in 15 rabbits. They were exposed to various ranges of temperature and air movement. The skin temperature at shorn and not shorn sites and heat flow were measured. The effect of cooling and air movement on skin temperature, thermal gradient and external thermoinsulation were calculated using statistical methods. It has been found that cooling, especially CD, clearly reduced the skin temperature, whereas the influence of air movement on skin temperature has been susceptible of various interpretations. Thermal gradients /skin temperature - air temperature/ increased as the cooling rlsed but their increase was higher at lower values of cooling /BCD/ than at higher values /CD/. The same relationship could be found in case of heat flow. The external insulation was dependet on cooling and at higher cooling values /CD/ it was lower than at lower values of cooling /BCD/. It proves that lower critical temperature for rabbits was exceeded when the experimental factor /CD/ appeared.

The exchange of heat energy between the body and the environment in homothermal animals depends among others on the temperature gradient. The increase in the body and skin temperature caused by the decrease in the ambient temperature is to reduce the thermal gradient which protects animals against stress of heat and cold. In the present study the authors examined the rate of changes of thermal gradient between the skin and the environment and changes in skin temperature, the rate of heat flow and insulating power of hair cover in rabbits according to the changes of environmental temperature. The measurements were made at various sites of the skin: thermostabile and thermolabile, not shorn and shorn. Considerable dopendence of skin temperature on the environmental temperature, especially at the thermostabile sites, shorn has been observed although the drop in skin temperature did not catch up with the drop in air temperature. The values of those gradient influenced the value of heat flow from the body to the environment.
