It was found out that with increasing of altitude, the amounds of calcium, phosphorus, potassium, magnesium, iron and copper in the milk from studied Karakachan sheep decreased and that of zinc was elevated. The influence of the moth of the study was the lowest upon calcium, potassium, sodium and manganese levels, more expressed in phosphorus and copper levels and the highest - on magnesium, iron and zinc concentrations. During the studied period, the average content of calcium in sheep milk varied between 0.136-0.144%, of sodium- between 0.04-0.045%, of magnesium- between 12.2-12.7 mg/100 g, of copper- from 0.07 to 0.076 mg/100 g, of zinc - from 0.5 to 0.618 mg/100 g, of iron - between 0.132-0.204 mg/100 g and that of manganese - between 0.015-0.016 mg/100 g.
