[Heat dissipation through the floor in piglet housing].
Trials were performed in 1980 and 1981 to test a new methodical procedure of measuring heat flow with Alfameter and to evaluate the dissipation of heat via the floor in piglet finishing houses with three large pig herds. It was demonstrated during the period of the study that slatted floors dissipated much more heat from the house, as compared with solid floors. The comparison of the density of heat flow over steel slats and plastic slats showed that the plastic slats wasted less heat: in the winter season the difference was 65 to 125 W/m2 and in summer 20 to 75 W/m2. In the houses with steel slats the comparison of heated and unheated lying place showed that the heat flow emitted from the lying place reduced the dissipation of heat via the slats.
