Abstract


The investigation monitored some haematological and biochemical parameters that characterise iron metabolism in cows during the last month of pregnancy and in their calves during the first three days of life. Haemoglobin and hematocrit were 11.8% and 8.5%, respectively, lower and sideremy was 34.5% higher in the pregnant cows that were cared for improperly, with low protein diets, compared to the cows that received proper diets. The newborn calves from the cows maintained and fed properly had 5.6% and 7.9% values for haemoglobin and, respectively, hematocrit than the calves that resulted from improperly nourished cows. In both categories of calves sideremy had lower values, close to the lower physiological limit, which requires the preventive supplemental with iron of the newborn calves. At birth calves weight was positive correlated with their haemoglobin value and those of their mothers too.

Key words: haemoglobin, hematocrit, sideremy, pregnant cows, new born calves
