Abstract:
The energetic utilization of 12 technically dried roughages (6 legumes, 5 grasses, 1 straw) with a wide variation of the chemical composition (crude fibre content 190-395, crude protein content 61-266 g/kg DM) was tested with 8 adult pigs each by means of the respiration test technique. The experiments were laid out according to the difference method with 3-4 basal ration period per animal. The digestibility of the energy of the feedstuffs (except straw) ranged from 40-60%, the partial utilization of the metabolizable energy from 63 to 74%.
