A New Salt Mixture for Use in Experimental Diets

Abstract
A new salt mixture has been described in which the proportion of calcium to other constituents has been greatly increased. This preparation, made by mixing dry salts, may be used at the level of 2% in many diets of purified foods which usually require 4% Osborne and Mendel salts. In experiments designed to compare the two salt mixtures during a selected period of active growth, from 60 to 200 gm. body weight, at a rate in excess of 5 gm. a day, adequate calcification of the femora has resulted with an average daily intake of approximately 50 mg. calcium and 35 mg. phosphorus.
