Objective: The objective was to compare Ca serum concentration and frequency of severe [Ca < 2.0 mmol/L] and moderate [Ca < 2.125 mmol/L] subclinical hypocalcemia (SCH) in cows supplemented according to the Dietary Cation Anion Differences (DCAD) principles or with synthetic zeolite.Materials and methods:The trials were performed in two large commercial farms in US and blood samples were tak ...

IntroductionMost cows undergo some level of hypocalcemia in the immediate postpartum period, with 40 to 70% of multiparous cows developing subclinical hypocalcemia (SCH; Reinhardt et al., 2011; Caixeta et al., 2015; Neves et al., 2017).Supplementing zeolite A in prepartum rations improves Ca status during the peripartum period (Thilsing et al., 2006; Pallesen et al., 2008).In European studies, fee ...

Introduction• Most cows are unable to elude some level of hypocalcemia in the immediate postpartum period, with 40 to 70% of multiparous cows developing subclinical hypocalcemia (SCH; Reinhardt et al., 2011; Caixeta et al., 2015; Neves et al., 2017).• Supplementing anions in prepartum rations is a common strategy to improve blood Ca concentrations however, SCH is often not eliminated (Le ...
