The objective of this study was to evaluate the dynamics of the body condition score, acute phase proteins (serum amyloid A and haptoglobin) and their relationships in dairy cows of the Slovak Pied Cattle from 3 weeks before parturition to 9 weeks after parturition. Significant differences were found in the means of serum amyloid A ( P  &lt; 0.01). Haptoglobin concentrations increased from 172.0 ± 0.05 µg/ml to 173.0 ± 0.13 µg/ ml at week 3 and week 1 before the parturition, respectively. The highest value of haptoglobin was recorded in cows 3 week  post partum . Cows during the early postparturient period had significantly higher serum amyloid A concentrations compared to cows in the prepartal period ( P  &lt; 0.01). Significantly higher body condition score values were observed in dry cows (from 4.42 ± 0.20 to 4.25 ± 0.15 points) than in cows after parturition (from 3.90 ± 0.12 to 3.25 ± 0.08 points) ( P  &lt; 0.001). In the assessment of correlations between the selected acute phase proteins significant positive correlation was found (r = 0.213,  P  &lt; 0.05). Moreover, negative correlations were found between the body condition score and acute phase proteins. Our results show a strong relationship between the decrease of the body condition score and the increase of acute phase proteins in dairy cows around parturition which indicates the process of a certain form of non-specific inflammation at loss of body fat.
