title: [Experimental study of the effect of a milk substitute on the secretory activity of the stomach in young rats].
abstract: Experiments were made on rats kept on artificial feeding. The animals were divided into two groups. The first group received a milk substitute from the 15th to the 21st day of life. The milk substitute was a liquid diet similar to the composition of rat's milk as regards the main indicators, containing 10% of protein represented by a mixture of casecyte and cow's milk serum proteins. The second group received the substitute once on the 21st day of life. Artificial feeding was shown to lead to a decrease in the pH of gastric chyme and to a rise of the total acidity calculated per mg protein of the chyme as compared to the respective indicators in animals on breast feeding (the third group). As compared to the third group animals, the concentration of pepsin in the gastric chyme increased 5- and 3.5-fold in the first and second group animals, respectively.
