The difference in cumulative yield between the normocalcemic and severe SCH groups was statistically significant ( p = 0.030), indicating that SCH negatively affects cumulative milk production, particularly in more severe cases. Multiparous cows produced significantly more milk (3,454.42 ± 114.84 kg) than second-parity (3,296.42 ± 128.19 kg) and first-parity cows (2,637.15 ± 121.14 kg), with a highly significant difference ( p < 0.001).
