Vitamins and trace minerals are necessary elements for normal functioning of the organism, and these substances must be in sufficient quantities in chicken feed. The assumption was that the body of chickens accumulate a sufficient amount of vitamins and trace elements and their exclusion from diet at the end of fattening period, 12, 8 and 4 days, had no negative impact on the ash and trace element content in the drumstick meat. The experiment was set up with 1400 chicken, divided into 7 groups. Vitamin and mineral supplements are excluded from chicken diet from 30 to 42 days of fattening period. Ash, iron, zinc and copper content were analyzed in drumstick meat. The results show that exclusion of these supplements did not have negative effects to the research parameters.Vitamini i mikroelementi zbog svoje važnosti za normalno funkcionisanje organizma pilića hranom se moraju unositi u dovoljnim koncentracijama. U istraživanjima se pošlo od pretpostavke da se u organizmu pilića akumuliraju dovoljne količine vitamina i mikroelemenata i da njihovo isključivanje pri kraju tovnog perioda, 12, 8 i 4 dana, nema negativnog uticaja na sadržaj pepela i mikroelemenata u bataku pilića. Eksperiment je postavljen na 1400 pilića, podjeljenih u 7 grupa. Vitaminsko-mineralni dodaci isključivani su iz koncentrata od 30-42. dana tova. Analiziran je sadržaj pepela, gvožđa, cinka i bakra u bataku pilića. Rezultati istraživanja pokazuju da isključenje vitaminsko-mineralnih dodataka nije imalo negativnog efekta na sadržaj ovih materija u bataku pilića
