Correlation between the Concentration of Polycyclic Carcinogens in Foodstuffs ofAnimal Origin and in the Feed of Agricultural Animals

摘要

To increase the production of dietary protein of animal origin various methods ofprotein and vitamin supplementation in stock raising are under development. Great significance is attributed to protein-vitamin concentrates, obtained microbiologically from different types of raw material, including non-food products (1-4). Meanwhile in some types of feeds carcinogenic polycyclic hydrocarbons may be found. They may be present not only in products of microbiological synthesis and processed non-food raw material, but also in some forms of byproducts of the food industry, used in livestock raising even in the main feed ration.
