Holstein Cow Genomic Longevity Study with Lifetime Health and Production Data

A longitudinal controlled cohort study tracked 36 Holstein-Friesian cows for over 10 years under uniform conditions. The dataset includes lifetime phenotypes such as milk yield, composition, reproductive performance, survival time, and detailed veterinary diagnoses, collected by Morteza Hosseini Ghaffari and published in 2026. It compares cows stratified by genomic functional longevity breeding values while being matched for milk production potential.

Use Cases

• Model herd retention and culling patterns based on genomic functional longevity breeding values.
• Analyze disease burden progression across lactations using detailed veterinary diagnoses.
• Compare reproductive efficiency metrics like calving interval between genetically stratified groups.
• Investigate correlations between somatic cell count, udder health, and genomic merit.

Strengths

• Longitudinal data spanning over 10 years of uniform management.
• Stratified cohort of 36 cows with a large difference in genomic functional longevity breeding values (Hedges' g = 24.7).
• Includes detailed lifetime phenotypes: milk production, composition, reproductive performance, survival, and veterinary diagnoses.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Dataset is small in scale (478.0 KB), indicating limited scope.
