Metabolic profile refers to the analysis of blood biochemical parameters used to assess and prevent metabolic and nutritional disorders in dairy farms. This study aims to evaluate the effect of magnesium on energy balance and metabolic profile parameters in fresh postpartum dairy cows. The study included 30 cows diagnosed with postpartum hypomagnesemia and 10 control group cows. Measurements of the parameters urea, creatinine, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transferase (GGT), total protein, cholesterol, albumin, calcium, phosphorus, beta-hydroxybutyric acid (BHBA), and non-esterified fatty acids (NEFA) were performed on biochemical analyzer. In the hypomagnesemia group, NEFA, total protein, AST and cholesterol levels were higher compared to the control group, while glucose levels were lower. Correlation analysis revealed a negative moderate correlation between magnesium and NEFA, BHBA and AST, positive moderate correlation with glucose and urea. Significant changes were detected in NEFA and glucose parameters, which reflect energy status, and in AST and cholesterol parameters, which provide information about liver function. It was concluded that metabolic adaptation in dairy cows affected by hypomagnesemia may be weakened, and energy balance and liver function may be affected.
