[Loss of heat through the skin in piglets in pigsties with and without windows].
In 1980 and 1981 tests were performed to verify the new methodical procedure of measuring heat flow by means of Alfameter and to evaluate the liberation of heat from the skin of piglets kept in two-storeyed cages in the finishing houses of the TEROZ TACHOV type. One of these houses was windowless, the other had windows. The temperature, humidity and flow rates of the air inside the houses were measured at the same time. The comparison of the two types of houses showed that under the given conditions the houses with windows implied a higher rate of cooling and a higher density of heat flow over the skin of the weanlings. In the windowed as well as windowless houses, the pigs in the upper row of cages showed a higher rate of heat liberation from the skin, as compared with the lower row. The piglets kept in the windowed house had lower gains and lower mortality rates.
