Abstract: The aim of our study was to determine the effect of single nickel administration as well as co–administration with zinc on distribution of potassium and magnesium in the muscle tissue (musculus longissimus dorsi, musculus biceps femoris) of rabbits. In the experiment 25 female rabbits of broiler line Californian were involved. Animals were divided to three groups: K (n=5) – control; P1 (n=5) – received 17.5 g NiCl2.100 kg-1 of feed mixture, P2 (n=5) – received 35 g NiCl2.100 kg-1 of feed mixture (FM), P3 (n = 5) – received 17.5 g NiCl2.100 kg-1 and 30 g ZnCl2.100 kg-1 of feed mixture and P4 (n = 5) – received 35 g NiCl2.100 kg-1 and 30 g ZnCl2.100 kg-1 of feed mixture. Animals were fed ad libitum using KKV1 feeding mixture with or without nickel and zinc addition for 90 days. For analysis of the content of these trace elements in 50 samples of animals an atomic absorption spectrophotometry method was used. The significant higher value (p<0.05) of potassium in musculus longissimus dorsi in group P2 was detected (17141.70±3702.40 µg.g-1) in comparison with group P3 (9594.39±2205.10 µg.g-1). The significant higher value (p<0.05) of potassium in musculus biceps femoris in group P3 (24489.78±3977.98 µg.g-1) in comparison with group P4 (14986.14±3530.84 µg.g-1) and group K (13100.24±2597.61 µg.g-1) was measured. The average concentration of magnesium in musculus longissimus dorsi was significantly higher (P<0.05) in P2 (1434.10±172.49 µg.g-1) group than those in group P1 (802.50±209.98 µg.g-1). Other differences remained insignificant (P>0.05).
