The experiments were carried out in white, non-breeding, male rats of different ages (15 days, 1 month, 1.5 months, 2 Months, 3 months and 4 months). Rats in the control group were fed a diet consisting of protein, fat, carbon dioxide. Experimental rats were also fed additional protein (egg white) to these feeds. Rats fed with protein-rich nutrients increased the synthesis of enzymes (amylase, lipase) that we have learned in the gland tissue, and the secretory activity of the glands accelerated its formation in postnatal ontogenesis, as well as their absorption into the blood, which in turn ensures an improvement in the recirculation of these enzymes in the body, and the glands
