Badania rozkładu temperatur na skórze i powierzchni ciała oraz przepływu strumienia ciepła u krów mlecznych

17 thermostabile and 9 thermolabile sites were used to measure the skin and body surface temperatures and the heat flux flow of 12 dairy cows. Obtained data supplied Burton's indicator of blood circulation, external and internal thermal insulation. Results indicate that in the range of the trunk /thermostabile sites/ the anterior body parts of examined cows were warmer than their posterior parts; the thermal situation was contrariwise as regards limbs /thermolabile sites/, where the fore legs were warmer than the hind legs. The remaining biothermal indexes corresponded to the temperature levels of the skin and body surface: the warmer parts were characterized by higher values of heat flow and Burton's circulation indicator only by lower levels of thermal external and internal insulation than the cooler parts. Differences between the warmer and cooler body parts of animals were statistically essential in relation to each of the discussed factors.
