Eggshell Quality and Gene Expression in Hens with Bile Acid Supplementation

A study by Liang Chen investigated the effect of dietary bile acid supplementation on eggshell quality in late-laying hens. The dataset likely contains results from 72 hens across three groups, measuring production performance, eggshell ultrastructure, and shell gland gene expression. Findings suggest bile acid supplementation improved eggshell calcium content and structural integrity by upregulating biomineralization genes.

Use Cases

• Analyze the correlation between gene expression levels (e.g., CALB1, CA2, OC-116) and eggshell thickness/mammillary density.
• Compare production performance metrics (e.g., laying rate, feed efficiency) across peak-lay, late-lay, and supplemented late-lay hen groups.
• Investigate the relationship between calcium concentration in shell gland fluid and overall eggshell quality.
• Model the impact of nutritional interventions on biomineralization pathways for functional food applications.

Strengths

• Dataset is derived from a controlled study with 72 laying hens assigned to three distinct treatment groups.
• Includes multiple measurement types: production performance, eggshell ultrastructure (mammillary density, thickness), and transcriptomic analysis of shell gland tissue.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 13.5 KB, indicating limited scope.
