Mineral Concentrations of Magnesium and Calcium in Relation to Diestrus and Proestrus in Ongole Crossbred Cows

Abstract

This research aims to e7amine the mineral concentrations of magnesium and calcium in relation to diestrus and proestrus cycles  in  Ongole  crossbred  cows.  Serum  was  taken  from 6 Ongole crossbred cows for the detection of its calcium (Ca) and Magnesium (Mg) during which the 3 cows were in diestrus cycle and the 3 other were in proestrucs cycle. The results revealed that the concentration of Mg in the diesterus cycle tended to be higher (2.47±0.39 mg/dL) than that in the proestrus cycle (2.40±0.27 mg/dL) although the Mg concentration during these two cycles did not differ significantly (P>0.01). Ca concentration in diestrus cycle (2.26±0.13 mmol/L) was higher than that in proestrus (2.11±0.07 mmol/L) although both of diestrus and proestruc cycles did not significantly differ (P>0.01). As a conclusion, the concentration of Ca and  Mg  during  the  diestrus  cycle  tended  to  be  higher compared to that during the proestrus cycle in the blood of Ongole crossbred cows.
