Abstract:
Low values for urea were found in samples of ruminal fluid of sheep fed concentrate rations if urea determination was carried out by the urease method. The present paper describes a both simple and sensitive colorimetric method of analysis using diacetyldioxime. The method is suitable for determining urea in coloured solutions such as ruminal fluid or silage extracts.
