The effect of hydrochloride-free, casein-simulated amino acid mixture on growth and food intake in young rats was studied. Weight gain of rats fed a hydrochloride-free amino acid diet ad libitum was greater than that of rats fed an amino acid diet containing basic amino acids in hydro-chloride form due to an increase in food intake. A hydrochloride-free amino acid diet was, however, still considerably inferior to a casein diet in supporting growth. Addition of sodium bicarbonate to the amino acid diet containing amino acid hydrochloride had no effect on ratt growth.
