Abstract

Results of the researches on contend of micro- and macroelements in blood and hair of calves in several husbandries of Belarus are presented in the article. In blood of calves at complex «Veseysky pokrov» and complex «Narochanskie zori» a low content of phosphorus, potassium, selenium and iron was determined, at «Veseysky pokrov» - copper. Selenium content in calves is 2-3 times lower than the minimal physiological level. Haur research of calves showed the low copper, manganese, selenium and zinc levels. Analysis data show high variability on this value in comples « Veseysky pokrov » (74,8±7,5) and complex « Narochanskie zori » (30,4±0,3).
