The aim of this study was to determine the content of copper, zinc and iron in cow's milk and detect possible significant deviation of these elements from literature data and causes for this. Milk samples were randomly taken fro 15 cows Holstein-Friesian by hand milking. All cows were captive breeding under the same conditions of feed and breed. Atomic spectrophotometry was used for the determination of copper, zinc and iron contents. The results of this investigation have shown that mean values of copper (x=263.33 microgram/L), zinc (x=4445.80 microgram/L) and iron (x=1153.33 microgram/L) content are in agreement with literature data. Only zinc shows the increase because of the larger intake of this element. So we can say that this milk is good for human nutrition, disregarding the mentioned values of copper, zinc and iron.
