The paper presents the analytical procedure of organic acids quantification in compound feed by ion chromatography method. Organic acids: acetic, propionic, formic, malic, fumaric, and citric were extracted from a feed sample with water for 30 min. The measurement was done by conductometric detection. The limit of quantification of the assayed acids in the feeds was as follows: acetic 0.50 g/kg, propionic 0.63 g/kg, formic 0.45 g/kg, malic 0.45 g/kg, fumaric 0.50 g/kg, and citric 0.45 g/kg. The coefficient of variation ranged from 0.40% to 1.68% and its mean value was 0.82%. Mean Horrat ratio amounted to 0.35, thus confirming very good precision of the method. The recovery rate of the acids added to the compound feed ranged from 97.2% to 102.5%, with the average of 99.4%.
