Abstract

The aim of this study was to determine the evolution serum levels of Ca, K, and Na in dairy cows with retained placenta (RP) and dystocia. Fourty-five cows between 3-10 years old were used in the study. Jugular blood samples were collected via hiparined vacutainer tubes. The samples were centrifuged and the serum samples were stored at -20°C until analyse. Calcium (Ca), Sodium (Na), and Potassium (K) were determined in all samples using a Roch® COBAS Integra 400. In this study, Na serum levels were significantly higher (p<0,05) in 48 post-partum hours' cows with 139,91±7,1 mmol/l compared with dry period with 131,09 ±11,09mmol/l. However, mean serum calcium levels were 79,50±10,47 and 79,25±8,39 mg/l in cows with retained placenta in dry period and 48 hours' post-partum, respectively. The mean serum sodium levels in cows with retained placenta in dry period and 48 hours postpartum were134,00±10,99 and 137,88±5.64 mmol/1 respectively. Whereas, in case of cows without retained placenta, the sodium values for the same period were130,46±11,15 and 140,35±7,37 mmol/1, respectively. In this study, the serum Ca, Na and K concentrations of the cows with RP did not change significantly from other cows without. Furthermore, it was detected that these variables had no significant effect on serum Ca, K and Na concentrations when type of parturition and sex of calves were evaluated in the RP and control group.
