Background: Subclinical hypocalcemia (SCH) is a metabolic disorder in dairy cows occurring during early lactation due to increased calcium demand. It is associated with health complications, reduced feed intake, and economic losses. However, its direct impact on milk production remains controversial.
Aim: This study aimed to determine the effect of SCH on cumulative milk production, peak milk production, and time to peak production during the first third of lactation in intensively managed Holstein cows in Lima, Peru.
Methods: A total of 483 Holstein cows from three intensive dairy farms were monitored from calving until 100 days in lactation. Cows were classified into normocalcemic (≥8 mg/dL), mild SCH (≥6.8 and
