This study evaluated the relationship between serum magnesium concentration, peri‑ and postpartum disorders, and reproductive performance in dairy cows. Blood samples were collected from 198 Holstein cows 4 weeks prepartum, after calving, and 1, 2, 4, 6, and 8 weeks postpartum to measure serum magnesium and/or progesterone concentrations. To determine the relationship between serum magnesium concentration and peri‑ or postpartum disorders, cows were divided into two groups based on their mean serum magnesium concentration 4 weeks prepartum and just after calving: a Low-Mg group (1.45–2.65 mg/dL, n = 110) and a High-Mg group (2.70–5.40 mg/dL, n = 88). Analysis of these groups showed that the incidences of dystocia, retained placenta, endometritis, and lameness were lower (P
