INFLUENCE OF BIOLOGICALLY ACTIVE SUBSTANCES ON THE MINERAL COMPOSITION OF RENAL TISSUE OF BULLS ON DIET WITH HIGHER CADMIUM CONCENTRATION
Abstract
Rising of man-caused impact on environment requires continuous monitoring of heavy metals in organs and tissues of animals, as a factor of quality of produced animal products. The mineral composition of renal tissue of bulls on adjusted diet with metionate of Fe, Cu, Zn, Mn, Co was under the research. Conducted studies showed that concentration of cadmium in the kidneys of bulls of agricultural company «Bovshivska» was higher on 35,9 mcg / kg (36,2 %; P <0.001). Adding to the diet the metalloorganic premix decreased cadmium level by 33,2 – 41,1 % (P <0,01 - 0,001), use of vitamin injections and methionine had no effect on the value of the indicator. The content of iron, copper, cobalt was higher in renal tissue of animals of agricultural company «Bovshivska».
