Serum Mineral Concentrations in Pasture-Grazed Dairy Cows After Calcium Bolus Treatment

New Zealand data from a 2024 spring calving season trial on 129 dairy cows from two commercial farms. The dataset compares serum calcium, magnesium, and phosphorus concentrations over 72 hours in cows treated with a new calcium-plus-vitamin-D bolus, a commercial calcium-only bolus, or no treatment. The research was authored by Emma Cuttance and shared under a CC-BY-4.0 license.

Use Cases

• Compare the efficacy of different oral calcium bolus formulations based on serum mineral time-series data.
• Model the time-course of serum calcium, magnesium, and phosphorus levels after calving based on treatment group.
• Analyze associations between treatment type and serum mineral concentrations, adjusting for farm, cow age, and sampling time.

Strengths

• Data originates from a prospective, randomized, controlled trial with 129 cows, providing a structured experimental basis.
• Includes repeated measures of serum total calcium, magnesium, and phosphorus from 0 to 72 hours post-enrolment.
• Statistical analysis used mixed linear regression models adjusted for farm, cow age, and sampling time.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to 129 cows from two farms in New Zealand during a single season, potentially limiting generalizability.
