Abstract
Investigations of the performance of growing pigs in the live weight range of 30 to 60 kg kept individually and in groups with ad libitum and rationed feeding were carried out in two air-conditioned rooms. The air temperature in the individual experiments was 20 degrees C, 10 degrees C and 5 degrees C, the relative atmospheric moisture in all experiments was between 70 and 80%. A diminished growth of 24 g per day per degrees C below 20 degrees could be ascertained for pigs kept individually. The diminishing of the growth can be compensated by an increase of the feed intake of 1.3 g per kg live weight, day and degrees C resp. the intake of metabolisable energy of 4 kcal per kg live weight, day and degrees C until the capacity of feed consumption is reached.
