Conteúdo:

1. The relative merits of trichloroacetic acids, sodium tungstate with H2SO4 and alcohol
have been compared as pricipitants in the estimation of N.P.N. in rumen ingesta.
2. A description is given of the methods finally adopted for the estimation of N.P.N., and
NH3.
3. The heterogeneous nature of the rumen contents is described and illustrated by analy-
ses.
4. The difficultiues involved in the interpretation of the results obtained by in vivo experi-
ments are discussed.
5. Owing to these difficulties, the results of in vivo experiments of this type cannot be
regarded as supplying evidence either for or against the theory that urea is converted to protein in the rumen.
