Abstract: The objectives of this study were to determine whether liquid feeding or TMR feeding of glucogenic and mineral supplements can improve metabolic status and plasma metabolits in Holstein fresh cows. Multiparous cows (n = 24), second lactating cows (n = 24) and first lactating cows (n = 24) were used in a completely randomized block desighn, immediately after parturition with 3 weeks experimental period treatments were: Control Treatment (CONT) without any aditive on water or TMR (CONT), Derenching treatment (DRCH) include: 40 L water contained: 2 kg of calcium propionate, propylene glycol, potassium chloride, magnesium sulfate, sodium phosphate, sodium chloride, sodium bicarbonate, choline chloride and methionine, feeding treatment (FEED) contained 2 kg of drenching diet contents that were mixed with TMR, compound diet (DRFD), 20 L water contained 1 kg of drenching treatment plus 1 kg of these materials that mixed to TMR. Treatments had significant effects on Ca, Mg and P concentrations of plasma (p<0.05) and these metabolites had more concentrations in DRCH treatment than others. DRCH treatment had positive effects on negative energy balance and plasma NEFA and β-HBA concentrations. Plasma glucose had increased significantly by treatment. Therefore, addition of these glucogenic precursers and minerals on water of fresh cows resulted in optimize animalmetabolic status in postpartum period.
