Description
Summary:Nowadays, one of the environmental problems is the pollution of the environment with heavy metals, the release of which leads to accumulation in the body of animals. The aim of the research was to study the content of heavy metals in the body of cows of different breeds in a separated agricultural enterprise. Researches were held in LLC "EIF Solyanskoe" of Krasnoyarsk region. The objects of research were the blood, urine and milk of cows Red-Motley breed and Black-Motley breed at the age of the second lactation. The result of research determined that concentration of Cu, Zn and Pb in milk and blood serum of Red-Motley cows was more than in Black-Motley cows; on the contrary, in urine the concentration of the studied metals was higher in Black-Motley cows. In general, the content of heavy metals in milk, blood serum and urine of cows of both breeds did not exceed the maximum permissible concentrations, with the exception of Pb in milk, the existence of which was slightly higher than the hygienic norm by 0.02-0.03 mg/kg.
