The aim of this study was to evaluate the effect of different source of magnesium in prepartum diets on productive performance, blood metabolites, insulin resistance and health disorders in transition cows. Sixty cows from 21 days prepartum were randomly assigned to 4 experimental treatments. Treatments were control treatment (Mg at NRC recommendation), magnesium sulfate treatment, magnesium carbonate treatment and magnesium oxide treatment (Mg was 0.60% of ration DM). Experimental diets increased DM and NDF digestibility (P<0.05). However, Calf and placenta weight, body weight changes and BCS were not affected by treatments. The incidence of retained placenta and hypomagnesemia decreased in experimental treatments (P<0.05). Magnesium oxide and carbonate treatments tended to increase milk yield (P=0.08). Milk fat increased in the control diet (P<0.05). Experimental diets decreased plasma NEFA and cholesterol and improved plasma Mg and Ca (P<0.05). Control treatment had the lowest rate of glucose CR (%) and RQUICKI (P<0.05).
