Summary The studies were carried out on 48 8‐week‐old Swiss male mice. The animals were divided into those selected for body weight gain (experimental) and an unselected (control) group. Twelve selected and unselected mice received a high protein diet (40%) during 14 days while the remaining 12 selected and 12 controls received a low protein feed (10%). In the lysosomal fraction of the liver and kidney, the activities of alanyl aminopeptidase, leucyl‐aminopeptidase, cathepsin D, L, acid phosphatase, lysosomal esterase, lysosomal lipase, beta‐galactosidase, beta‐glucosidase, beta‐glucuronidase, N‐acetyl‐beta‐glucosaminidase were measured. The results obtained suggest that the different dietary protein levels (10 and 40%) and selection changed the activity of lysosomal enzymes studied in the liver and kidney of experimental mice.
