The determination of uric acid in animal feeding stuffs using high-performance liquid chromatography

Abstract

A method is given for the extraction of uric acid from animal feeding stuffs that contain dried poultry waste. The extract obtained is analysed by high-performance liquid chromatography using a strong anion-exchange bonded silica column and an ultraviolet method of detection. Results of a series of recovery checks together with those for the analysis of actual samples are given. The application of the method to ammonium urate additions is investigated.
