Conteúdo: 	Abstract: The "empty rumen technique"  was  developed  to  determine  the  botanical  and chemical  composition  of  the  diet  ingested  by  domestic  ruminants  feeding  in  dense thornbush vegetation where oesophageal fistulation proved impractical. The rumen of a  fistulated  animal  is  emptied,  washed  and  filled  with  a  sterile  isotonic  salt  solution, the rumen content is retained. The animal is then allowed to feed for a defined time period, the rumen is emptied again and refilled with the original contents, The rumen material  obtained  can  be  used  to  determine  botanical  and  chemical  composition  of the   ingested   material,   particle   size   and   dry   matter   intake.   Rumination   and fermentation are negligible for approx. 3 hours due to the prior treatment. Correction factors  for  absorption  and  outflow  of  soluble  components  were  established  in  stall feeding   experiments  under   controlled   conditions.  Simultaneous   preference  and feeding  behaviour  observations  with  Small  East  African  Goats  on  a  semi-arid thornbush savannah yielded no significant differences between "empty rumen" and control  animals  for  all  observed  parameters.  No  short  and/or  long  term  effects (growth rate, vitality, health status) on the animals were observed, when the intervals between experiments were longer than two weeks.
