Abstract

ABSTRACT
The serum concentration of macroelements such as sodium and potassium as well as red blood cell
associated traits like total red blood cell count, haemoglobin content, volume of packed red cells and erythrocyte
indices were determined in crossbred heifers. The screening of macrominerals and RBC traits were undertaken in
st heifers before and after conception at regular intervals as well as during the 1 month of lactation. The serum
concentration of sodium increased while potassium fluctuated as pregnancy advanced. The total RBC count
th reached the lowest value by 9 month of gestation. This reduction was compensated by the increase in MCV. The
haemoglobin content and VPRC exhibited a declining trend throughout the period of gestation.
