ABSTRACT
The objectives of this study were to examine whether drenching or mixed with total mixed ration (TMR) of glucogenic and mineral supplements can prevent metabolic disorders of 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 design, immediately after parturition and for 3 weeks experimental period. The treatments used were: 1) the control treatment that without any addition on water or TMR (CONT), 2) drenching treatment (DRCH) that include: 40 liter water contained 2 kg of the glucogenic and mineral supplements drenched to cows in two equal meals, 3) feeding treatment (FEED) contained two kg of the glucogenic and mineral supplements mixed with TMR, 4) compound diet (DRFD ), 20 liter water contained 1 kg of glucogenic and mineral supplements drenched to cows plus 1 kg of these materials mixed in the TMR. DRCH treatment had positive effects on negative energy balance and plasma NEFA and BHBA concentrations. Plasma glucose had increased significantly by treatments (P
