Podstawą rozważań było wykorzystanie energii cieplnej wytwarzanej przez tuczniki utrzymywane w temperaturach otoczenia zgodnych z zaleceniami CIGR i SFBIU do uzyskania odpowiednich warunków siedliskowych. Wykonane obliczenia wskazują na możliwość uzyskania optymalnych efektów produkcyjnych bez konieczności dogrzewania pomieszczeń.

Thе considerations were based on the amount of thermal energy emitted into the environment by porkers in technologically conditioned growth temperatures, advised by CIGR and SFBIU, as well as on features characterising the metabolism of porkers, such as oxygen consumption, amount of produced CO; and vapour. The data showed that it is possible to maintain the temperature of 20°С in the hog house, with the outside temperature drop to 3°C. Therefore, this is the boundary outdoor temperature for the proper development of thermal balance for piglets weighing up to-20 kg. For porkers, the optimum thermal conditions of 13°С can be obtained with the outside temperature decrease down to -20°C. The calculation carried out point to the possibility of obtaining optimal production effects in porkeries with no need of heating them, even during unfavourable external conditions.
