Various technique were tried and those adopted for use under local conditions are described in detail. Regression equations were calculated which compare crude protein and fiber content of samples collected from fistulas with those of forage eaten. Figures present the composition of saliva before and after feeding and an equation correlates yield of saliva to the dry matter of forage eaten. Possible reasons for the differences between the herbage fed and the forage collected are discussed.  aCattle  aForage  aSheep  aTropical pastures  aRuminante  aFistulacao  aFistulation  aPlanta Forrageira Tropical1 aTORELL, D.
