Abstract

Many multiparous dairy cows experience subclinical hypocal­cemia (SCH) in the immediate postpartum period as they adapt to the demands of lactation. Furthermore, differing dynamics of SCH in the days following parturition are associated with varied health and production outcomes, with cows experienc­ing transient SCH producing more milk and facing fewer nega­tive health events than cows with delayed or persistent SCH. Our objectives were to describe differences in mediators of Ca homeostasis between cows experiencing different dynamics of SCH.
