The work examines calcaemia and phosphataemia in cows during the antepartal and postpartal periods and their connection with the incidence of abomasal displacement. The experiment covered 30 cows in advanced stages of gravidity. Blood samples were taken two weeks before expected parturition and two weeks after calving. Following parturition, left displacement of the abomasum was established in seven of the 30 cows covered by experiment. The remaining 23 cows in the experiment were clinically healthy, they were placed in a group and represented control animals. The average value of calcaemia for the control group of cows during the antepartal period was 2.72+/-0.25 mmol/l, and the phosphataemia 2.04+/-0.25 mmol/l. In the same cows postpartum, average calcaemia values were 2.46+/-0.22 mmol/l, and phosphataemia 1.85+/-0.29 mmol/l. The average antepartal value for calcaemia in the experimental group of cows was 2.51+/-0.25 mmol/l, and for phosphataemia 1.73+/-0.22 mmol/l. The average values for this group of cows postpartally was 2.13+/-0.31 mmol/l for calcaemia and 1.43+/-0.24 mmol/l for phosphataemia. The differences between the concentration values for calcium and phosphorus obtained postpartally between the experimental and control group were statistically significant.
