| Abstract: | The energetic utilization of raw and steamed sugar beets, raw carrots and fresh conserved or dried sugar beet pulp was measured at 8 adult pigs each with the application of the respiration experiment method. The experiment was laid out according to the difference method with 4 periods of basic rations per animal. The digestibility of the energy of the 5 feedstuffs (sequence as above) was measured as 85, 87, 83, 67 and 69% and energy retention as 10.1, 9.8, 9.1, 8.2 and 8.1 MJ/kg DM. In comparison to earlier measurings (Schiemann et al., 1966) digestibility was by 4%, relatively, lower. Under consideration of the difference in the digestibility of energy, there is very good agreement in energy retention. |
