| Abstract: | Changes in blood plasma calcium, inorganic phosphorus, magnesium, zinc, iron, copper, sodium and potassium concentrations over a 3-year period were investigated in primitive goats. Blood plasma mineral concentrations were determined by atomic absorption and a colorimetric method. Changes in Zn and Ca concentrations are season dependent, potassium levels show only a long-term change tendency, and magnesium and inorganic phosphorus had constant levels throughout the investigation period. Iron, copper and sodium showed both long-term change tendencies and more or less marked season related changes. |
