Abstract

We studied the content of Cadmium, Lead, Strontium and Nickel in the biological systems: environment – feed – animal – livestock products in agroecological conditions of Zacarpathian region. It is noted that the content of Cadmium and Strontium in soil samples taken from commercial land PAL «Lastochka», Uzhgorod district, Zacarpathian region did not exceed the maximum allowable concentrations, whereas the levels of Lead and Nickel were higher. The content of investigated elements in water used for watering cows in farm was 0.02–1.02 mg/l and did not exceed the maximum allowable concentrations which is up to veterinary and sanitary requirements. It is known from the literary sources that there is interdependency between the heavy metals level in soil and their accumulation in farming cultures. The obtained results of the study of heavy metals in feed (hay, straw, wheat, mixed fodder) harvested on the farm did not exceed the maximum allowable concentrations of studied elements in feed rations for animals. It is known that heavy metals in fodder transform in animal organism and have influence on the intensity of metabolic processes, physiological and biochemical condition and animal productivity. Concentrations of the elements in cows’ whole blood and hair were within physiological values. Absolute content of Cadmium, Lead, Strontium and Nickel in the milk of studied cows were under 0.014; 0.02; 0.15 and 0.2 mg/kg, respectively and did not exceed the maximum allowable concentrations.

The analysis of coefficient of correlation between the heavy metals content in biological systems: environment – feed – animal – livestock products revealed the strong correlation between the heavy metals content in soil and water, in straw and mixed fodder, in blood, hair and milk, and the poorly expressed correlation between their content in catena: water – straw – blood – milk.
