Abstract
As part of the investigations proceeding in this laboratory on the physiology and nutrition of sheep, the cyst(e)ine (cystine plus cysteine, calculated as cystine) and methionine contents of two large samples of mixed rumen bacteria were determined. The samples Were obtained from slaughterhouse rumens selected to represent sheep from ‘dry' and ‘green' feed conditions respectively, the absence of green material in the rumen being taken to indicate ‘dry'-fed and its presence to indicate ‘green'-fed animals.
