Very intensive modern breeding systems, comparing to earlier technologies in poultry, suppose much higher nutritional requirements. For instance, if copper level is higher than requirements, in well balanced diet it has stimulative effect on performances of poultry, but it accumulates in tissues and affects the health of human consumers. To investigate the pattern of its accumulation in muscles and other organs, and experiment with 150 one-day old Hybro chickens was carried out. At the end of the trial it shows that 100 and 200 ppm of copper had a stimulative effect, and its concentration in the tissues was within normal physiological limits (28.6 and 30.75 ppm). Higher level of copper in the diet (400 ppm) increased its content in the liver to 113.2 ppm. Cumulative effect of copper in kidneys and muscles was quite low and did not show any correlation with its content in the feed.
