Description
The study was performed on 40 clinically healthy cows during late pregnancy and early lactation period (peripartum period) which were examined for total blood counts and biochemical blood parameters. At the late pregnancy period the mean difference between the values of erythrocytic count, total leukocytic count, proportion of eosinophils, serum calcium, phosphorus, creatin-kinase, gamma -glutamyltransferase, urea, copper and zinc values were significantly (p < 0.05) decreased. The mean difference of the proportion of unsegmented neutrophils, sodium, aspartate-aminotransferase and bilirubin values were significantly (p < 0.05) increased. During early lactation the mean of difference between haemoglobin content, haematocrit value, erythocytic count, the proportion of unsegmented neutrophils, serum sodium, potassium, creatin-kinase and bilirubin values were significantly (p < 0.05) decreased. Magnesium,-glutamyltransferase, total protein, urea, copper and zinc values were significantally (p < 0.05) increased. It was concluded that these changes in blood parameters are considered to be physiological changes which place the animal more or less under physiological metabolic stress and can lead to the production of claw horn with poor quality.
