• Simmental cows
• Blood Serum
• Calcium
• Phosphorus
• Magnesium

The results of inorganic blood parameters are presented in the periparturient period and during lactation of Simmental dairy cows. Serum calcium and inorganic phosphorus in blood of dairy cows in puerperium were significantly lower (p<0.05) compared to the values in the blood of dairy cows in advanced pregnancy and during peak of lactation, probably indicating the increased use of these macro-elements by the Simmental cows' mammary gland at the early stages of lactation. When the cows were in the periparturient period serum magnesium levels were significantly lower (p<0.05) compared to the values of dairy cows during their maximal lactation probably indicating the increased use of magnesium by the Simmental dairy cow during the periparturient period.
