[Effect of the meat of farm animals fed new nitrogen-containing food additives on the morphologic features of the internal organs in the rat].

A study was made of the internal organs of rats fed the meat of agricultural animals whose diet included non-protein nitrogen-containing compounds--urea, isobutylidene diurea and a polymer, carbamide with polyacrylamide. Morphological studies have demonstrated that inclusion into the diet of experimental rats of the meat of young bulls given isobutylidene diurea and urea leads to structural alterations in the internal organs of rats, the most pronounced alterations being detected in experiments with the use of the meat of young bulls given isobutylidene diurea. The feeding of experimental rats with the meat of animals grown with the use of the polymer did not affect the morphofunctional status of their organs.
