Abstract: Heating piglets in nursery and farrowing may be improved to save energy, without affecting the animals' welfare. The objective of this research was to compare the electrical energy use and thermal environment promoted by three heating technologies for piglets in nursery. The heating technologies studied were: TR - suspended electrical resistors, TP - heated floor and TA convection heating. Electrical energy consumption (kWh), maximum power demand requirements (kW), specific consumption (kWh/kg of produced live body weight), efficiency of heating system (degrees C/m(3) air) and dry-bulb temperature (degrees C) and Temperature-humidity Index (THI) were evaluated. The heated floor system was better under the aspect of electrical energy use. The electrical resistance heating system was the best regarding to the animals' thermal comfort needs.
