Blood Metabolites during Pregnancy and Postpartum in Dairy Cows

This study was performed in the University of Khartoum teaching dairy farm during the period extended from January to April 2020. It was designed to investigate blood glucose total protein (TP) calcium (Ca) phosphorus (P) magnesium (Mg) iron (Fe) and triiodothyronine (T3) during late pregnancy and postpartum period (PPP). Thirty apparently healthy multiparous cross-bred dairy cows (Friesian × Kenana) were included in this study and the offered diet consists of roughages and concentrates. The cows were allocated to three groups according to their physiological status.The results of this study indicated that there was a significant difference (p<0.01) in concentration of plasma glucose TP Fe and T3 during late pregnancy postpartum period (PPP) and non-pregnant cows. In conclusion blood glucose serum Fe and TT3 were found high during late pregnancy while TP was found low compared to PPP.
