[Influence of various physical forms of the feed on the energy metabolism of ruminants. 3. Investigation of the energetic utilisation of rations with roughage treated with various mechanical methods].
In a total of 170 experiments with the complete metabolism of fullgrown sheep the energy utilisation of rations with roughage treated with different mechanical methods was investigated. The roughage feedstuffs dried green fodder of vetch/grass, lucerne and rye grass and straw were given to 4 parallel animals in 9 rations with differing quotas of concentrates (0 to 60%). The roughage underwent the following 5 methods of treatment: 1) chopping; 2) chopping and pelleting; 3) grinding; 4) grinding and pelleting; 5) grinding and pelleting with concentrates. The results show that the bases given in the GDR system of feedstuff evaluation concerning the energetic evaluation of feedstuffs are to be applied to mechanically treated roughage too. In order to avoid negative effects on the energy metabolism one has to take care that the use of mechanically treated roughage does not cause dysfunctions of the rumen.
