Relationship between Copper and Zinc Content in the Soil and Plants and their Consequent Content in Blood and Excrements of Cattle and Sheep under Various Forms of Breeding

The aim of the study was to explain the relationship between copper and zinc content in the soil and plants and their consequent content in blood and excrements of cattle and sheep while various forms of breeding. Apart from the Cu and Zn concentration in the soil samples we were investigating also the concentrations of the elements Ca, Mg, P, Na, K, Mn and Mo. In excrements and feeding rations the concentration of copper and zinc were investigated. Beef cows and heifers (143) without the market milk production, dairy cows and heifers (182) with the market milk production and sheep (191) were included in the project. Altogether 325 blood (excrement) samples were collected and examined. The relations between haematological indicators and copper and zinc metabolism appear more often in animals (cows, heifers, sheep) with nonconventional way of farming and it is impacted by many the impact of an antagonistic influence of elements than in dairy animals. The results also show the necessity of the controlling of the supplementation with the mineral elements accumulation in the soil samples, plants and organism
