The components of one castrated Boar's urine, which was fed with formula feed, formula feed combined with comfrey and combined with ladino clover, were examined; three kinds of urines were daily gathered. Ethyl acetate extracts of each sample were fractionated into acidic, phenolic and neutral parts. In ether soluble acidic part of three kinds of extracts, benzoic, phenylacetic, β-phenyl-propionic and cinnamic acids were identified, of which the main component was found to be benzoic acid. In phenolic part, phenol, p-cresol and p-ethylphenol were also identified in all cases. In the cases of feeds combined with grasses p-cresol was found to be the main component.
