Relationships between hematological parameters and Cl and Na homeostasis in dairy herds and abortion

Abstract

Abortion is among reproductive parameters affecting the profitability of dairy herds. Abortion incidence is influenced and/or controlled by different infectious, environmental, and managerial factors and so forth. The effect of environmental and nutritional conditions on minerals, as well as interactions between minerals and physiological conditions, are leading parameters to consider during gestation. This study attempts to assess links between these factors and abortion by determining and measuring homeostasis-electrolyte factors, such as Na and Cl, and hematological parameters, such as complete blood count, in dairy herds with abortion. A total of 40 Holstein dairy herds were chosen and split into two 20-member control and aborted groups. Abortions were reported by ranchers, and blood samples were taken considering the history and current status of herds and clinical examinations. Blood samples were taken twice, once with EDTA to study hematological characteristics and once with no anticoagulant to measure hemostasis-electrolyte factors (Na, Cl) from the serum of herds with abortion. The relationships between these parameters and variations observed in dairy herds with abortion were compared with those in the control group. There was no significant difference in concentrations of sodium and chlorine between the two groups (p> 0.05).
