[Hygienic significance of the use of feed antibiotics in animal husbandry].

Introduction of kormogrisein-10 and fradizin-10 into feeds of farm animals did not lead to accumulation in the animals' meat of grisin and tilozin residues or to an adverse effect of such meat on the body of experimental rats. In the course of oral administration of the preparations to the animals the authors determined the period of detectability of antibiotic residues in muscles and organs and the minimal toxic doses of the preparations.
