ABSTRACT:

Heavy metals have high biological activity, tend to accumulate in separate links of the biological cycle and to enter the organism of animals in trophic chains, accumulating and negatively affecting their vital activity. The aim of the research was to study the effect of various doses of the adsorbent oftetacinum calcium on the morphological and biochemical values of the blood of the Hereford bull calves fed on rations with a higher content of heavy metals.Methods of research.Scientific and economic experiment was conducted on the Hereford bulls, for which four groups of 10 heads each were formed using the pair-analogue method. In the course of the studies, the bulls of 1 (control) group got the basal diet (BD), and the ration of animals of 2, 3 and 4 (trial) groups were supplemented withtetacinum calcium at the rate of 0.5; 1.0 and 1.5 g / 100 kg of live weight. The results were processed statistically by the Student’s methodology using the software package "Microsoft Excel".Results of the research. In the conditions of excessive content of heavy metals in feeds, feeder bulls of the3experimental groupwhich received the preparation of tetacinumcalciumat the rate of 1.0 g / 100 kg of live weight werecharacterized by the best level of intermediate metabolism. In the blood of the bulls of the 3 test group, the highest content of erythrocytes and hemoglobin was found, which exceeded the control by these parameters by 0.45 × 1012 / l and 0.98 g / l, respectively. The highest concentration of cadmium - 0.129 mg / kg, lead - 1.68 mg / kg and zinc - 30.75 mg / kg, was observed at the age of 18 months in the serum of young animals of group 1, and the lowest in animals of group 3, yielding to them in saturation of these toxicants, respectively, by 26.8, 30.6 and 48.8%. Although the concentration of zinc, lead and cadmium in the blood of the youngsters of the 3 test group exceeded the maximum concentration limits, their level was approaching the lowest point of this level. Key words: feeder bulls, heavy metals, adsorbent, detoxification, morphological and biochemical values of blood.
