In the article, results of researches on an establishment of an optimum level of polyphenolic carbon complex from Antarctic black yeast Nadsoniella nigra are resulted. Experimental studies conducted in terms of problem research laboratory of feed additives National University of Life and Environmental Sciences of Ukraine. Independent experiment was conducted with laying quails. We conducted a randomized block experiment with 4 treatments, each with 4 replicates of 12 laying birds (42 to 252 d of age). It was experimentally established that feeding quails polyphenolcarbonate complex from Antarctic black yeast Nadsoniella nigra, the basis of which is melanin, in the compound feed at 0.5 mg / kg increase in egg production by 3.1% to the initial and 2.0% to the average laying quails. Feeding the complex at the level of 0.5 mg / kg contributed to a probable intensity of egg production, namely by 1.8% and increased feed conversion by 1.7%. The use of polyphenolic carbon complex from the Antarctic black yeast Nadsoniella nigra in the feeding of laying quails did not affect their safety and reduce the probable egg productivity
