Summary. The article presents the results of studies that reflect the informativity of various biological markers (feather, hair) to assess the elemental status of model animals. The experimental part of work was carried out on the «Hisex Brown» model of chickens and Wistar rats.

It has been established that an increase in the content of chemical elements (sodium, phosphorus, chromium, iodine, nickel, arsenic, and vanadium) in hair of experimental rats is accompanied by a significant decrease in their exchange concentration in the body.

Evaluation of informativity of feather as a biosubstrate characterizing the elemental status of 10-18 week bird revealed a close correlation between the mineral composition of feather and body in  ten elements, including calcium (r=-0.748), phosphorus (r=-0.564), cadmium (r=-0.639), lead (r=-0.6); strontium (r=-0.664),chromium (r=-0.692), iodine (r=-0.731), manganese (r=-0.765), nickel (r=-0.727) and selenium (r=-0.890).

Thus, size of the pool of elements in the organism of animals is possible to estimate using the study of the composition of the «model» biosubstrates (wool, feather) and taking into account the specific metabolic factors in the organism.

Key words: chickens, rats, trace elements, biosubstrates, feather, wool, blood.
