The Use of Orally-fed Liquid Formulas in Metabolic Studies

Abstract

Oral formulas as a sole source of nutriment proved to be valuable in a variety of metabolic studies. Patients had no difficulty in taking liquid feedings for periods up to 16 weeks. Dogs, in one experiment lasting 10 weeks, maintained weight or gained. As compared to mixed natural foods, formulas have the advantages of constant and defined composition, economy, and ease of preparation. A few basic formulas can meet the needs of various metabolic studies. The three most useful in our experience are described.
