[Comparative study of the protective effects of 3 carboxylic acids on urea and ammonia toxicity in sheep].

Three carboxylic acids (acetic, propionic and citric) were compared as to their protective effect in controlling the toxic and lethal action of urea in sheep. It was derived from the metabolic and clinical studies that citric acid was the most effective of all the acids studied and can be used in the preventive treatment of sheep against the toxic lethal action of urea and ammonia. The mechanism of the action of citric acid is also discussed in relation with other findings.
